| # 20:57:25 | fauno | o/ |
| # 20:59:17 | fauno | y_morin: sorry to bother you every day... :) |
| # 20:59:30 | fauno | i got the final glibc |
| # 20:59:37 | y_morin | fauno: hello! Good! :-) |
| # 21:00:10 | fauno | i removed the --libdir --libexecdir flags and the double sysroot was gone |
| # 21:01:17 | fauno | but while building the final gcc i discovered it was just looking for libs at /usr/$target/lib and glibc has libs on this dir and /usr/$target/usr/lib (most on this one) |
| # 21:01:53 | y_morin | fauno: you mean, relative to the sysroot? Or absolute paths? |
| # 21:02:13 | fauno | absolute |
| # 21:02:22 | y_morin | BAAADDD!!!! |
| # 21:02:27 | y_morin | Just a sec... |
| # 21:04:01 | fauno | sysroot is /usr/$target |
| # 21:04:15 | y_morin | fauno: I have no toolchain here (I trashe all with a bad "rm -rf") so I'm bulding one to look at the structure |
| # 21:04:42 | y_morin | fauno: Ha... |
| # 21:04:56 | y_morin | fauno: and what --prefix do you give gcc ? |
| # 21:05:23 | fauno | /usr |
| # 21:06:36 | y_morin | fauno: OK, not really related to your issue, I guess, but I would *highly* suggest that you do *not* install in /usr! |
| # 21:06:56 | fauno | anything? |
| # 21:06:57 | y_morin | fauno: not until you've debgged your build scripts, at least. |
| # 21:07:38 | fauno | i'm using a package manager on a chroot so i'll notice if it wants to overwrite something |
| # 21:08:15 | y_morin | fauno: yes, a chroot is the minimum! ;-) |
| # 21:08:22 | y_morin | fauno there are three rules: |
| # 21:08:32 | y_morin | 1) don't build as root |
| # 21:08:43 | y_morin | 2) glibc's prefix is /usr |
| # 21:09:05 | y_morin | 3) gcc's sysroot is a subdir of gcc's prefix |
| # 21:09:56 | y_morin | The first will tell you if the install tries to install files where it should not, because you'll not have appropriate rights to do so |
| # 21:10:12 | fauno | i think i have all of the covered |
| # 21:10:12 | y_morin | The second will already saw, it's glibc's black-magic |
| # 21:10:24 | fauno | makepkg uses fakeroot |
| # 21:10:45 | fauno | and gcc is prefix=/usr sysroot=/usr/$target |
| # 21:11:07 | fauno | is that ok? |
| # 21:11:27 | y_morin | fauno: just a sec, the toolchain is almost built, here... |
| # 21:11:34 | fauno | that was quick |
| # 21:11:44 | y_morin | fauno: yes, it looks sane to me |
| # 21:12:20 | y_morin | fauno: hyper-threaded hexa-core + 6GiB RAM + 4x HDD is RAID5... *That* is a fast machine, indeed ! :-) |
| # 21:12:37 | y_morin | but still, too slow for me... :-] |
| # 21:12:37 | fauno | ok the error is that target-ld fails just after libgcc ends |
| # 21:13:03 | fauno | it tries to use /lib/libc.so.6 |
| # 21:13:10 | y_morin | fauno: are you doing reall cross compilation, or just something like i386 -> x86_64 ? |
| # 21:13:20 | fauno | i686 -> mips64el |
| # 21:13:31 | y_morin | Ah, true cross-compile, then |
| # 21:14:23 | y_morin | fauno: caould you try, just to check, with gcc's (and binutil's) prefix set to a depper directory, such as ${HOME}/test |
| # 21:14:35 | y_morin | deeper |
| # 21:17:25 | fauno | so rebuild binutils and gcc with prefix=!/usr |
| # 21:17:50 | y_morin | fauno: that would rule-out that gcc has black-magic if --prefix is /usr (I doubt it, though) |
| # 21:18:26 | fauno | sysroot? |
| # 21:19:16 | y_morin | fauno: sysroot must be below the new prefix, eg: prefix=/home/toto/test and sysroot=/home/toto/test/$target |
| # 21:19:28 | y_morin | fauno: hold on! |
| # 21:19:49 | fauno | jumps and rolls |
| # 21:20:13 | y_morin | In crosstool-NG, we use a sysroot like : ${prefix}/${target}/sysroot |
| # 21:20:27 | fauno | aha... |
| # 21:21:05 | y_morin | Notice that the sysroot is not exactly the same as yours. Yours is the place used before sysroot support existed. And there are corner cases to that... :-( |
| # 21:21:34 | fauno | but i'm using prefix and sysroot |
| # 21:22:39 | fauno | btw since glibc installed libs on $sysroot/lib and $sysroot/usr/lib and gcc was only looking at first one |
| # 21:22:56 | y_morin | fauno: not too sure about this... :-/ I know it works here when prefix is not /usr and sysroot is ${prefix}/${target}/sysroot |
| # 21:23:16 | fauno | i symlinked them (from usr/lib/* to lib/*) |
| # 21:23:19 | y_morin | fauno: yes, I think that was the behavior before sysroot support was added |
| # 21:23:44 | fauno | so sysroot=/usr/$target isn't an actual sysroot? |
| # 21:23:47 | y_morin | fauno: just a sec... |
| # 21:24:28 | fauno | i can show you my glibc contents |
| # 21:24:51 | y_morin | fauno: http://crosstool-ng.org/hg/crosstool-ng/file/188d58cfe7cf/scripts/crosstool-NG.sh.in#l268 <- look at the 'else' branch of the 'if' |
| # 21:25:20 | y_morin | fauno: and although it is called 'sysroot', it does not behave as such. |
| # 21:27:07 | fauno | i have to go i'll be back in a few minutes |
| # 21:27:13 | y_morin | fauno: see ya! |
