| # 08:17:26 | bhundven | kos_tom: I didn't know uClibc built statically. I was just looking at ctng to see if it built it that way. |
| # 08:18:23 | kos_tom | bhundven: I believe that being to link statically is one of the main difference between uClibc and glibc, next to support for non-MMU platforms |
| # 08:18:43 | bhundven | that's pretty cool |
| # 08:20:06 | bhundven | in the last few months, I just started getting into the arm7-m stuff |
| # 08:21:08 | bhundven | so many people told me that mcu programming was a pita, but some of these vendors make it really easy. |
| # 08:22:07 | bhundven | and it's interesting to see linux ports for efm32 and the freescale mcus |
| # 08:23:15 | bhundven | nothing complete yet, but still interesting |

| # 20:56:47 | smartin_ | y_morin: ping? |
| # 20:58:58 | y_morin | smartin_: pong! |
| # 21:01:10 | smartin_ | is the CT_BUILD_SUFFIX fully supported? grepping the sources does not show that many matchs |
| # 21:01:45 | smartin_ | though tweaking the CT_BUILD tuples seems working fine... |
| # 21:02:36 | smartin_ | has some hard time building a cross-compiler mac for linux... |
| # 21:03:36 | y_morin | smartin_: There is no match on CT_BUILD_SUFFIX because the variable is made-up. See scripts/crosstool-NG.sh.in, line 406. |
| # 21:03:54 | y_morin | smartin_: however, I only used it a few times a long time ago, so it is possible it is broken. |
| # 21:04:32 | y_morin | smartin_: toying with the tuples is rarely a good idea, unless you know what you're doing. |
| # 21:05:25 | smartin_ | well, how does ct-ng guess the host tuple then? |
| # 21:06:18 | smartin_ | because using a gcc form macport, the result does not match any existing binary :-/ |
| # 21:06:20 | y_morin | smartin_: in cross-compilation, host is guessed by scripts/config.guess; in canadian, you have to provide host. |
| # 21:06:40 | y_morin | smartin_: The target is always derived from the config options, plus sanitising through scripts/config.sub |
| # 21:06:58 | y_morin | smartin_: and the build is always guessed by scripts/config.guess. |
| # 21:07:30 | smartin_ | arf... |
| # 21:07:52 | qsuscst | quits : Ping timeout: 256 seconds |
| # 21:08:04 | y_morin | smartin_: then a bit of munging so that we never have build == host or build == target or host == target (but only internally), so that gcc/binutils never assume they can run tests. |
| # 21:08:23 | y_morin | glibc, too. |
| # 21:08:24 | smartin_ | so, why is it allowed to set CT_BUILD* vars through menuconfig if it has no effect? |
| # 21:09:07 | y_morin | smartin_: becasue you may already have a compiler that is not 'gcc' but can be 'test-gcc' or 'gcc-4.7' or 'test-gcc-4.7' |
| # 21:09:17 | y_morin | and is not the default compiler on your system |
| # 21:09:45 | y_morin | smartin_: eg. gcc is /usr/bin/gcc but you may want to use /opt/test/bin/gcc-4.7 |
| # 21:10:08 | y_morin | smartin_: in that case: PREFIX=/opt/tests/bin/ and SUFFIX=-4.7 |
| # 21:10:28 | y_morin | smartin_: (in the cross-compilation case, I mean) |
| # 21:11:04 | smartin_ | in my case, it's x86_64-apple-darwin12-gcc-mp-4.5 in /opt/local/bin (which is in the PATH) |
| # 21:11:07 | y_morin | smartin_: For canadian, host can be eg. powerpc-unknown-linux-gnu, but your compiler can be named ppc-gcc-4.7 and then you have to provide prefix and suffix. |
| # 21:11:32 | y_morin | smartin_: Then: PREFIX=x86_64-apple-darwin12- and SUFFIX=-mp-4.5 |
| # 21:11:35 | qsusOFFcs | joins #crosstool-ng |
| # 21:11:56 | y_morin | smartin_: This is the native compiler you're speaking about, right? |
| # 21:12:00 | smartin_ | and it's failing running: 'x86_64-build_apple-darwin12-gcc' '-O2' '-g' '-pipe' ... |
| # 21:12:08 | smartin_ | y_morin: yes |
| # 21:12:29 | y_morin | smartin_: Then maybe SUFFIX is broken. Lemme see... |
| # 21:12:30 | smartin_ | i'm build a cross (no fancy) compiler |
| # 21:14:02 | y_morin | smartin_: can you pastebin your build.log, please? |
| # 21:15:58 | smartin_ | with what log level? |
| # 21:16:11 | smartin_ | is ALL enough? |
| # 21:16:24 | y_morin | smartin_: no, the *full* build.log |
| # 21:18:28 | y_morin | smartin_: or put it on a webserver where I can get it from |
| # 21:19:10 | smartin_ | http://code.bulix.org/mpwlzo-83577 |
| # 21:20:28 | y_morin | smartin_: First, static linking is impossible on Darwin/MacOS-X |
| # 21:21:14 | y_morin | smartin_: So you will want to disable bot: CC_STATIC_LIBSTDCXX and STATIC_TOOLCHAIN |
| # 21:21:39 | y_morin | smartin_: and GDB_CROSS_STATIC too |
| # 21:21:50 | Thomas1 | quits : Quit: Thomas1 |
| # 21:22:16 | smartin_ | arf yeah i will, just copy/paste remains from the linux configs |
| # 21:24:56 | y_morin | smartin_: and the suffix missing is expected: ct-ng constructs symlinks for internal use, in .build/TUPLE/buildtools/bin <- check that x86_64-build_apple-darwin12-gcc indeed points to your real x86_64-apple-darwin12-gcc-mp-4.5 |
| # 21:25:58 | smartin_ | well, it's better (now failing fetching some sources, but i can handle that). many thx |
| # 21:29:04 | y_morin | smartin_: cheers! |
