did you convert from a non-multilib system ? what does `ls / /usr` show ? does this work: echo 'main(){}' | gcc -x c - -m32 -o a.out
Hi What do you mean about the non-multilib conversion? It is 64 bit system with a x86 crossdev compiler.

your glibc or gcc is broken. i don't know how it got broken, but it is. you should grab a binpkg (either from another machine or from tinderbox) to recover. a correct setup with current amd64 multilib setups: - /lib and /usr/lib are symlinks to lib64 - /lib32 and /usr/lib32 contain 32bit libs/objs - /lib64 and /usr/lib64 contain 64bit libs/objs - `file /usr/lib32/crti.o` should show 32bit - `file /usr/lib64/crti.o` should show 64bit - `gcc -print-multi-os-directory` should show ../lib64 - `gcc -print-multi-os-directory` should show ../lib32 - `echo 'main(){}' | gcc -x c - -m32 -o a.out -v` should produce a 32bit a.out and should mention /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../lib32/crti.o - `echo 'main(){}' | gcc -x c - -o a.out` should produce a 64bit a.out and should mention /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../lib64/crti.o
Ok follow all your request. The only problem seems so be the fact that I can't produce a 32bit a.out. However I try to substitute gcc from tinderbox. But How Can I broke gcc or glibc ? I can't build new package without problem! mplinu / # ls -ald lib /usr/lib lrwxrwxrwx 1 root root 5 Feb 9 19:41 lib -> lib64 lrwxrwxrwx 1 root root 5 Sep 26 2009 /usr/lib -> lib64 mplinu / # ls -ald lib32 /usr/lib32/ drwxr-xr-x 3 root root 4096 Jun 6 09:28 lib32 drwxr-xr-x 42 root root 49152 Mar 21 17:11 /usr/lib32/ mplinu / # file /usr/lib32/crti.o /usr/lib32/crti.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped mplinu / # file /usr/lib64/crti.o /usr/lib64/crti.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped mplinu / # gcc -print-multi-os-directory ../lib64 mplinu / # gcc -print-multi-os-directory ../lib64 mplinu / # echo 'main(){}' | gcc -x c - -m32 -o a.out -v` should > ^C mplinu / # echo 'main(){}' | gcc -x c - -m32 -o a.out -v Using built-in specs.

I've substitued glibc too; with the same version glibc-2.13-r4 . However I faced the same problem while building glibc !
I dear, I've found the DOGMA! Some weeks agou I moved the /usr/lib64 in another FS: mv /usr/lib64 /mnt/fsmisc/ And then I linked is under /usr cd /usr ln -s /mnt/fsmisc/lib64 At that point I correct all links that point from /usr/lib64 to /lib64 .... Everything work properly...not everything. Howevere the problem was that when I build new package the link between /usr/lib and /lib were created with relative path without check. For example ls -al /usr/lib/libcrypt.so point to ../../lib64/libcrypt.so.1 but if the real fs FS is /mnt/fsmisc the lib is not reachable. So I think about the fact that no check are done in link creation in build process. Is it correct?
using symlinks for /usr or any dir under /usr (especially lib*) has never been supported, and is known to not work because many tools (like gcc) use relative paths across those points which completely break when using symlinks. there isn't really any ebuild we can add these checks because any package that calls `gcc` can fail.
That is not completely true because I have build a lot of packages without problem. However If you think that a link check is not useful thats will be.
as you found here, building any package with the non-native multilib will fail. there are other examples we've found over the years unrelated to gcc or multilib where using symlinks will also fail. that you merged some packages w/out a problem isn't terribly relevant -- you got lucky. since symlinks completely break relative paths, they are not allowed. there is no single ebuild we can sanely check for this setup.
