While the details previously mailed to me have alas now been lost, I believe there is an upstream libc fix for s390 which is not yet in the Debian package. In short, libpthread must be compiled with a certain pic option (-fPIC or -fpic, not sure which) to prevent the following relocation problem when compiling lam, for example:
cc -shared -Wl,-soname=liblam.so.4 -o debian/tmp/usr/lib/liblam.so.4.0 tmp/*/*.o -lpthread -lutil -ldl /usr/lib/libpthread_nonshared.a(pthread_atfork.os)(.text+0x24): In function `__pthread_atfork': /build/buildd/glibc-2.3.2.ds1/build-tree/glibc-2.3.2/linuxthreads/pthread_atfork.c:39: relocation truncated to fit: R_390_GOT12 __dso_handle collect2: ld returned 1 exit status
Hopefully Gerhard can give more information if needed.
Please let me know if this is a quick fix for Sarge, or whether I should attempt a workaround in lam.
Could you teach us more information about it and the fix? Glibc is not changed more than one year. If this problem has not been existed such a long time (over one year), I think it's related with the recent various toolchain updates. Note that it's similar problem with the recent binutils problem on mips (that problem is decided to not fix in the sarge).
Camm, Gerhard, did you know the following issues? (1) what the problem is (2) what the appropriate fix is (3) it's glibc specific problem. If it's difficult issue, I think it's nice to apply workaround patch to lam.
The problem is that libpthread_nonshared.a is compiled with -fpic but should be compiled with -fPIC as libc_nonshared.a already is. This would solve the lam problem.
Regards, Gerhard
