abb_inth.c: check all interrupt causes, not just one The original code used if - else if - else if etc constructs, thus the first detected interrupt was the only one handled. However, Iota ITSTATREG is a clear-on-read register, thus if we only handle the first detected interrupt and skip checking the others, then the other interrupts will be lost, if more than one interrupt happened to occur in one ABB interrupt handling cycle - a form of rare race condition. Change the code to check all interrupts that were read in this cycle.

50 a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	1 Preparing the development and build environment
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	2 ===============================================
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	3
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	4 In order to compile our FreeCalypso Tourmaline firmware, you will need a
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	5 Unix/Linux system. Even though we are using a compiler which we got in the
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	6 form of Windows .exe binaries and thus have to use Wine (see below), everything
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	7 that we have built on top of it is Unix-based. The Mother currently uses
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	8 Slackware Linux release 14.2 (32-bit) and previously used Slackware 13.37,
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	9 also 32-bit.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	10
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	11 You will need to install the following 3 pieces of software on whatever
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	12 machine you will use to run the FC Tourmaline build process:
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	13
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	14 1. Wine: self-explanatory. The Mother uses the following Slackware package:
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	15
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	16 https://www.freecalypso.org/members/falcon/slackware/wine-1.5.23-i486-1sg.txz

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	18 I originally used it with Slackware 13.37 and I am still able to use it
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	19 with 14.2 without any issues.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	20
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	21 2. FreeCalypso Wine environment:

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	25 Extract the content of the above tarball into your ~/.wine/drive_c
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	26 directory - that's all there is to it!
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	27
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	28 3. nowhine wrapper around Wine:
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	29
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	30 ftp://ftp.freecalypso.org/pub/GSM/TI_src/wine/nowhine.c
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	31
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	32 The purpose of this wrapper is to suppress the following obnoxious whine
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	33 which wine emits on my system:
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	34
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	35 preloader: Warning: failed to reserve range 00010000-00110000
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	36
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	37 Wine will also emits a bunch of other whines if you have to run it
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	38 in an environment without an X11 display (e.g., on a machine that you
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	39 ssh into), and our nowhine wrapper suppresses those as well.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	40
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	41 If wine does not emit those preloader whines on your system and you
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	42 never find yourself in a situation of having to run without an X11
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	43 display and thus you find our nowhine wrapper to be unnecessary,
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	44 you can skip the wrapper and create a nowhine symlink pointing directly
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	45 to wine.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	46
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	47 Compiling the local helper utilities
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	48 ====================================
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	49
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	50 (cd helpers; make)
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	51
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	52 Do the above. Most of the build helper scripts used in the FC Tourmaline build
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	53 system are written in Bourne shell, but a few were easier to implement in C.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	54 You need to compile these C helper utilities before you can run an actual FC
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	55 Tourmaline firmware build, but these utilities are totally ad hoc and specific
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	56 to the needs of our fw build system, hence they are not meant to be installed
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	57 globally on your system - instead they stay within the fc-tourmaline tree. You
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	58 just need to run make in the helpers directory once before any actual firmware
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	59 builds.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	60
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	61 Actually building the firmware
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	62 ==============================
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	63
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	64 In order to build our FreeCalypso Tourmaline firmware for a particular target
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	65 in a particular configuration, run a command like this from the top level of
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	66 the fc-tourmaline tree:
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	67
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	68 ./configure.sh luna2 bigcolor-gprs
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	69
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	70 The first required argument to the configure.sh script selects the hardware
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	71 target, the second required argument selects the functional configuration, and
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	72 any further arguments beyond these two (optional) allow changing various
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	73 configurable settings that go beyond basic functional selection and aren't
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	74 strictly fixed by the hardware target.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	75
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	76 As of this writing, the following hardware targets are supported:

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	90 The second required argument selects the basic functional configuration; these
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	91 functional config stanzas appear in the configs directory. The following
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	92 functional configurations are currently available:
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	93
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	94 bigcolor-gprs & bigcolor-vo

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	96 These are UI-enabled configurations with the big (176x220 pixel) color
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	97 version of the UI. These functional configs can be built only for
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	98 luna1 and luna2 targets.

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	102 Small B&W UI configuration - 96x64 pixel black&white UI version. This
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	103 functional config can be built for c139, luna1 and luna2 targets. When
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	104 running on Luna, the logical 96x64 pixel B&W LCD is centered in the

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	110 This one is a special intermediate configuration is that the UI layers
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	111 are built in the smallbw config, but the underlying R2D framebuffer
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	112 driver is 176x220 pixel B&W, rather than 96x64 pixel B&W. This config
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	113 can only be built for Luna targets; it originates from TI's own
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	114 configuration of running their !LSCREEN (smallbw) UI on D-Sample boards
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	115 with R2D driver in the BW_D_Sample config.

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	125 See the Voice-pseudo-modem article. This functional config is
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	126 applicable to c11x, c139, c155, j100 and pirelli targets.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	127
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	128 Each configuration is built in its own directory; the name of this build
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	129 directory takes the form of build-$TARGET-$CONFIG$SUFFIX, i.e., for the example
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	130 configure.sh line above, the resulting build directory will be named
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	131 build-luna2-bigcolor-gprs. The $SUFFIX part is empty by default, but can be set
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	132 on the command line in order to distinguish non-standard builds that had some
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	133 tunable settings changed to values other than the default. For example, if you
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	134 are building modem firmware for an FCDEV3B V1 board where you need to disable
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	135 sleep, you should run the configure script as follows:
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	136
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	137 ./configure.sh fcdev3b stdmodem DISABLE_SLEEP=1 SUFFIX=-nosleep
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	138
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	139 The build directory would then become build-fcdev3b-stdmodem-nosleep, and the
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	140 specified suffix will also be included in the firmware version ID string that
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	141 gets compiled into the image.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	142
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	143 To actually compile the firmware, cd into the created build directory and run
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	144 make there. Unfortunately the use of TI's proprietary compiler via Wine makes
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	145 the build quite slow, but there is a trick to speed it up: if you run some
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	146 other Wine program that stays open and does not exit on its own (e.g., wine cmd)
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	147 in another window and leave it open while you run your FC Tourmaline fw build,
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	148 the build will proceed much faster - the presence of another Wine process using
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	149 the wineserver environment will keep Wine from shutting this environment down
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	150 and restarting it for every individual cl470 run, i.e., for each individual C
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	151 source file.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	152
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	153 When the build is done, the flashable firmware image will be in fwimage.bin.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	154 This image is to be flashed with fc-loadtool at a target-dependent base address.

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	156 flashing command script for fc-loadtool that erases the correct range of flash
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	157 sectors and then programs fwimage.bin at the right address.

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	159 When building firmware for the FCDEV3B or for the Pirelli, one can build either
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	160 a flashable image or a RAM-loadable one - or both. Because this part of the
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	161 build system is common with other targets for which only flash images can be
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	162 produced, the Makefile always builds the flashable image by default -
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	163 fwimage.bin is always meant for flash and never for RAM. To build a RAM-
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	164 loadable image when the target allows it, run 'make ram' - the image will be in
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	165 ramimage.srec, which you can then load and run on the target with FreeCalypso
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	166 host tool fc-xram.

a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	168 Cached libraries
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	169 ================
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	170
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	171 In the build architecture of all TCS211-based firmwares including Tourmaline,
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	172 each fw component is first compiled into a linkable library (*.lib file with
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	173 TI's TMS470 toolchain), and then these libraries are linked together into the
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	174 final code image. Early in FreeCalypso project history many of these component
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	175 libraries were blobs, meaning that we had to use prebuilt libraries for which
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	176 we had no corresponding source. Our fw has now been almost fully deblobbed,
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	177 meaning that we have transitioned from blobs to recompilation from source for
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	178 almost all of our fw components. But this deblobbing has had an unfortunate
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	179 downside: because our Wine-based compiler is very slow, every time we deblobbed
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	180 a component library, build times would get longer and longer.
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	181
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	182 FC Tourmaline introduces a partial solution to this problem in the form of
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	183 cached libs. Some component libraries are completely independent of
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	184 configuration particulars, i.e., they remain exactly the same no matter which
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	185 Calypso target you are building firmware for, and are likewise unaffected by
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	186 our various supported functional configs. Prebuilt versions of these config-
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	187 independent libs have been checked into the cache directory of our source tree,
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	188 and Tourmaline fw builds use these cached libs by default. These cached libs
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	189 are NOT blobs in that we do have the corresponding source for them, and the
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	190 versions that are checked in have been built by us, not by any evil source-
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	191 withholding third parties. You can disable the use of cached libs and force
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	192 full recompilation from source by adding a USE_CACHE=0 argument to your
a62e5bf88434 first round of documentation Mychaela Falconia <falcon@freecalypso.org> parents: diff changeset	193 configure.sh line.
