| 07:52.30 | kos_tom | Jacmet, yeah, yet another remaining package converted to the *TARGETS infrastructure \o/ |
| 07:56.09 | Jacmet | kos_tom: indeed |
| 07:57.11 | Jacmet | I should build a bunch of external toolchains for the different options we have (largefile, char, locale, ..) - It takes ages to test all those combinations from scratch on my old laptop |
| 07:59.01 | Jacmet | kos_tom: I'm thinking of getting rid of PROGRAM_INVOCATION. It only adds trivial overhead to uclibc (I would guess <100 bytes) and we have quite some packages needing it |
| 07:59.02 | *** join/#uclibc sh4rm4 (~sh4rm@unaffiliated/sh4rm4) |
| 08:10.08 | kos_tom | Jacmet, if the overhead is only <100 bytes, then go for it. |
| 08:11.27 | Jacmet | kos_tom: it is. It's just a question about keeping track of 2 pointers based on argv[0] in the uclibc startup code |
| 08:11.56 | Jacmet | kos_tom: only problem is that we then wouldn't catch issues with people using external uclibc based toolchains without this option enabled |
| 08:12.15 | Jacmet | kos_tom: but ok, it didn't work before either |
| 08:13.49 | Jacmet | kos_tom: this is basically the added code: http://git.buildroot.net/uClibc/tree/libc/misc/internals/__uClibc_main.c#n410 |
| 08:14.57 | kos_tom | Jacmet, well, there are many, many, many custom uClibc configurations that we don't support. |
| 08:15.16 | kos_tom | Jacmet, in terms of external uClibc toolchains, I think we should only try to support those that are widely available. |
| 08:15.35 | kos_tom | Jacmet, for example, the one made available for Blackfin are well-known for this architecture, so it makes sense to worry about supporting them |
| 08:15.55 | kos_tom | Jacmet, but we can't support any random external toolchain with a custom uClibc configuration that one can be build with ct-ng |

| 12:08.39 | curfont | It wont run, I had the same problem with I was doing MIPS and it had the wrong endianess |
| 12:09.08 | Jacmet | curfont: armeb is very rare, so that's unlikely to be the problem |

| 12:12.58 | curfont | Nothing relevant, so for sure it is arm + Cortex A9? Maybe I need to do some other config? |
| 12:13.03 | curfont | I am using gcc 4.4 |
| 12:13.17 | kos_tom | curfont, did you link statically ? |
| 12:13.26 | curfont | yes: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, not stripped |
| 12:13.31 | curfont | Thats what file shows ^ |

| 12:14.00 | kos_tom | the error message reminds me of something, but I don't remember what. |
| 12:14.36 | curfont | kos_tom: I got the same error message when I tried running a mips app with the wrong endianess |
| 12:15.13 | Jacmet | curfont: what does file say for one of the "native" programs on your phone? |
| 12:15.33 | Jacmet | curfont: perhaps its using thumb2 |
| 12:17.07 | curfont | cat: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), stripped |

| 12:20.18 | Jacmet | curfont: no |
| 12:20.36 | Jacmet | curfont: google has its own libc |
| 12:20.58 | curfont | brilliant Jacmet, it worked |
| 12:21.05 | curfont | "stripping" |
| 12:21.19 | curfont | that shouldnt even cause this problem right? |
| 12:21.34 | curfont | seems android phones dont like unstripped executables |
| 12:26.03 | oktalogic | hm, stripping should only remove debug info and such no..? not affect the execetion otherwise..? |
| 12:27.32 | curfont | thats what I thought too |
| 12:27.46 | curfont | unless wget didn't get the file properly the first time |
| 12:27.48 | curfont | oh well |
| 12:32.26 | curfont | Is there some kind of script in the buildroot that will set the environment so make uses the correct gcc? |
| 12:35.05 | kos_tom | curfont, no we don't have anything like this at the moment |
| 12:38.19 | Jacmet | curfont: would that be anything else than export PATH=$PATH:$PWD/output/host/usr/bin ? |
| 12:38.33 | *** join/#uclibc Artemys (~quassel@stp25-2-82-234-232-91.fbx.proxad.net) |
| 12:38.48 | kos_tom | Jacmet, we could have a helper that sets an environment with CC=blabla-gcc LD=blabla-ld, etc. |
| 12:39.19 | curfont | Jacmet: usually, binaries are named arm-linux-gcc |
| 12:39.35 | curfont | Aha, I could make symlinks |
| 12:39.40 | curfont | and then set the path to them |
| 12:39.49 | Jacmet | kos_tom: true, we could. Wouldn't that cause more problems than it would fix for people who also wants to compile something with their system compiler now and then? |
| 12:39.59 | curfont | Hmm |
| 12:44.04 | kos_tom | Jacmet, we can document something like "Run commands this way: (source ~/buildroot/output/br-env.sh ; make)" |
| 12:44.25 | kos_tom | but it's a bit horrible |
| 12:45.05 | kos_tom | or make $(cat ~/buildroot/output/br-env.sh) |
| 12:45.39 | kos_tom | or simply, we could document what values should have the different variables |
| 12:46.17 | kos_tom | Jacmet, generally speaking, I'd like to improve our Buildroot documentation, add some tutorials, and stuff like that. I think we have reached a relatively good level of quality/stability (for the existing feature set), but we lack docs. |
| 12:46.36 | curfont | buildroot is awesome and simple if you just use gcc on its own |
| 12:46.43 | curfont | But makefiles, autoconf etc are a nightmare |
| 12:46.52 | Jacmet | kos_tom: yes. I don't really feel strongly about it. Here, I just tell people to add host/usr/bin to the end of the path and people know how to pass CROSS_COMPILE to make |
| 12:51.51 | curfont | has anyone built things like ncurses with uclibc |
| 12:52.21 | kos_tom | curfont, it's available as a package in BR, so yes. |
| 12:52.43 | curfont | ah, so there is a way to get it |
| 12:54.47 | curfont | kos_tom: http://buildroot.uclibc.org/buildroot.html#add_packages |
| 12:54.49 | curfont | is this how I add it? |
| 12:58.25 | kos_tom | curfont, no, ncurses is already available as a package, so someone has already done this work. Just run menuconfig and tick the option. |

| 15:52.02 | kos_tom | quotrem, well it depends. There are some tools that understand the difference between CC and HOSTCC |
| 15:52.08 | d33tah | when I compile it with a single applet, it complains "ether" is undeclared (i compiled it to support only ether-wake) |
| 15:52.10 | kos_tom | where CC = HOSTCC in native build, but CC != HOSTCC in cross-builds |
| 15:53.14 | quotrem | kos_tom: yeah but you have to do two builds right? "CC=host-gcc make xxx; CC=target-gcc make xxx" or equivalent, right? |
| 15:53.48 | d33tah | it's the latest busybox and i feel kinda lost |
| 15:54.32 | pedwo | quotrem, kos_tom: looking at it a bit more the host tool depends on a lib that is also built for the target so it will have to be seperate passes |
