| # 20:53:01 | ayaka | what is the problem? |
| # 20:53:25 | diorcety | y_morin: i submit again the gcc/cc split :) |
| # 20:53:38 | y_morin | ayaka: What library are you talking about? |
| # 20:54:01 | y_morin | diorcety: OK, I'll look at it when I get it! :-) |

| # 20:55:25 | breiker | joins #crosstool-ng |
| # 20:55:31 | y_morin | ayaka: And what program are you trying to build? |
| # 20:56:08 | ayaka | y_morin, a program is wroten by me |
| # 20:56:10 | ayaka | http://paste.debian.net/68951/ |
| # 20:57:02 | ayaka | does will cross ld read the ld.so.conf in sysroot/etc ? |
| # 20:57:07 | ayaka | will cross ld read the ld.so.conf in sysroot/etc ? |
| # 20:58:25 | y_morin | ayaka: No, ld.so.conf is parsed at runtime, not at build time. |
| # 20:58:43 | y_morin | ayaka: How do you check for the libx264 presence (can you share your configure.ac)? |
| # 20:59:07 | ayaka | y_morin, http://paste.debian.net/68953/ |
| # 20:59:45 | ayaka | I think I find the problem, as I place libx264 in sysroot/usr/lib/arm-linux-gnueabihf |
| # 20:59:53 | ayaka | I want to use multiarch |
| # 21:00:30 | y_morin | ayaka: No, you should place it in sysroot/usr/lib |
| # 21:00:55 | y_morin | ayaka: multilib is experimental and most probably broken in no-so-subtle ways. |
| # 21:01:27 | y_morin | ayaka: Also, you should use pkgconfig to test for the library, since libx264 install a x264.pc file |
| # 21:01:53 | y_morin | ayaka: Shen you install your library, just run: make DESTDIR=/path/to/sysroot install |
| # 21:02:05 | y_morin | ayaka: But Installing in the sysroot is ugly! |
| # 21:02:27 | y_morin | ayaka: It means your toolchain gets poluted, and you won;t be able to re-use it. |
| # 21:02:45 | y_morin | ayaka: Best to use an automatic system builder, like, say, Buildroot. |
| # 21:03:07 | ayaka | y_morin, yes, but I don't know how to use buildroot |
| # 21:03:34 | y_morin | ayaka: It's very easy! |
| # 21:03:52 | ayaka | y_morin, I have place libx264 in sysroot/usr/lib, but it doesn't work, I don't get pc file for it |
| # 21:04:02 | y_morin | ayaka: And it helps tremendously in cross-compilation. Just hop to #buildroot for help |
| # 21:04:40 | y_morin | ayaka: What do you get with: ls -l /path/to/sysroot/libx264* |
| # 21:04:42 | ayaka | y_morin, thank you |
| # 21:05:21 | ayaka | then another problem, if I have build the toolchain using croostool-ng, but I mess sysroot |
| # 21:05:41 | ayaka | is there a way to reinstall crosstool-ng without build again |
| # 21:06:08 | y_morin | ayaka: No, it;s not possible. If you know _exactly_ what you put there, you can remove it, otherwise you;re screwed. |
| # 21:06:29 | ayaka | y_morin, I have put too much things in it |
| # 21:06:38 | y_morin | ayaka: But if you _realy_ want to tinker with the content of the sysroot, then I'd suggest you do: |
| # 21:06:47 | y_morin | 1) build a toolchain from scratch |
| # 21:07:02 | y_morin | 2) create a tarball of that toolchain |
| # 21:07:30 | y_morin | 3) When you need to start again from a clean toolchain, remove the tainted one, and extract the tarball |
| # 21:08:31 | ayaka | y_morin, about buildroot, it seems that it can do what crosstool-ng do. so what is crosstool-ng used for? |
| # 21:09:28 | y_morin | ayaka: corsstool-NG is only about building a toolchain; Buildroot is about building a complete system |
| # 21:09:54 | y_morin | ayaka: Buildroot is very limited in the versions it can build, while crosstool-NG is (tries to be) very versatile. |
| # 21:11:00 | ayaka | y_morin, yes buildroot seems that it can only build for uclibc, but my platform is eglic |
| # 21:13:42 | y_morin | ayaka: No, Buildroot can build with glibc. eglibc and uClibc (and musl, too). |
| # 21:13:54 | ayaka | y_morin, I see thank you |
| # 21:14:00 | y_morin | ayaka: And Buildroot recently gained the ability to build (e)glibc-based toolchains, too. |

| # 21:28:41 | ayaka | y_morin, thank you |
| # 21:29:16 | ayaka | but there is still a problem, buildroot doesn't support too as many packages as debian |
| # 21:29:27 | ayaka | y_morin, I have to use that way |
| # 21:29:41 | y_morin | ayaka: You mean you're trying to build for an existing system? |
| # 21:29:59 | ayaka | y_morin, yep |
| # 21:30:13 | sh4rm4 | joins #crosstool-ng |
| # 21:30:15 | y_morin | ayaka: So you should use the tools of that system. |
| # 21:30:46 | ayaka | y_morin, well, I don't know which tools I shall use |
| # 21:31:18 | y_morin | ayaka: Look at the Debian documentation. |
| # 21:31:29 | ayaka | y_morin, thank you |
| # 21:31:43 | y_morin | ayaka: And by the way, try to hit them on the head for doing their insane multiarch thingy at the same time! :-) |
| # 21:31:53 | y_morin | ayaka: Cheers! |
| # 21:32:48 | ayaka | y_morin, if I don't use sysroot, where shall I place the builded libraries? |
| # 21:34:02 | y_morin | ayaka: That's the whole point of using a buildsystem rather than manually compiling: it does all of this for you. |
| # 21:34:27 | y_morin | ayaka: You can install wherever you like, and then pass -L flags to tell were you installed them. |
| # 21:34:53 | ayaka | y_morin, if i use -L, I shall use -rpath as the same time |
| # 21:37:40 | ayaka | y_morin, " Also, you should use pkgconfig to test for the library, since libx264 install a x264.pc file" means that my way to check libraries is wrong? |
| # 21:55:00 | protomouse | quits : Quit: this is not a drill |
| # 22:07:05 | ayaka | , does sysroot is in search path of default crosstool |
| # 22:09:53 | y_morin | ayaka: Yes, the cross-compiler will search the sysroot. |
| # 22:10:32 | mingwandroid_ | joins #crosstool-ng |
| # 22:11:11 | ayaka | y_morin, the it is the problem of gnu autoconf |
| # 22:11:40 | ayaka | y_morin, as it is in search path, but it doesn't find libraries in sysroot/usr/lib |
| # 22:12:21 | ayaka | modify pc file is too difficults, there are two many |
| # 22:13:11 | y_morin | ayaka: Then you should really try to either use the tools for Debian, or use a buildsystem like Buildroot. |
| # 22:15:37 | ayaka | y_morin, but the debian way is using multiarch but it is not done yet |
| # 22:16:02 | ayaka | y_morin, well but I wonder why it will casue problem |
| # 22:17:26 | y_morin | ayaka: The Debian tools do support multiarch (mind you, multiarch != multilib). |
