Compiled gcc version 4.3.0 20070602 with tzdata 2007b-1 and libc6 2.3.6.ds1-13 everything went well enough and "make -i check" was not too bad ...
Decided to upgrade. Everything compiled fine until the _last_ library (of course), otherwise it would have worked fine. wget http://ftp.debian.org/debian/pool/main/t/tzdata/tzdata_2007f-6_all.deb wget http://ftp.debian.org/debian/pool/main/g/glibc/libc6_2.6~20070518-2_i386.deb dpkg -i tzdata_2007f-6_all.deb dpkg -i libc6_2.6~20070518-2_i386.deb Notes in /etc/init.d/glibc.sh # The GNU libc requires 2.6 kernel (except on m68k) because we drop to support linuxthreads # HPPA boxes require latest fixes (2.6.9 ) in the kernel to function properly. # The GNU libc is now built with --with-kernel= >= 2.4.1 on m68k Notes in /usr/share/doc/libc6/README All Linux kernel versions prior to 2.6.16 are known to have some bugs that may cause some of the tests related to pthreads in "make check" to fail. If you see such problems, please try the test suite on the most recent Linux kernel version that you can use, before pursuing those bugs further. # Echo Yes, this is a "legal" command # /lib/libc-2.6.so GNU C Library stable release version 2.6, by Roland McGrath et al.

In the follow-up message http://gcc.gnu.org/ml/gcc/2007-04/msg00884.html Martin ends up with the same problem as I have but on a different platform and not as a result of having made an upgrade and breaking things. It ended up that no solution was given and there were no more follow-ups. I don't know that the config.logs should be that different but I do know my fix made no use of the info - perhaps it will help someone else.

File: /usr/share/doc/libc6/ChangeLog.nptl - Last updated 2007-05-14 - says: What always will work is to use the API glibc provides. Compile and run the following little program to get the version information: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #include <stdio.h> #include <gnu/libc-version.h> int main (void) { puts (gnu_get_libc_version ()); return 0; } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The file: gcc-4_3-trunk/libgomp/libgomp.h says "#include <pthread.h>". Change that to: /* #include <pthread.h> */ #include <nptl/pthread.h> And the build completes a minutes later - no errors. Just add the above function to the configure to check the libc6 version and set a define to select between "pthread.h" and "nptl/pthread.h" and it would work. We need both defines since it works fine on libc6 2.3.6.ds1-13 on i686-pc-linux-gnu without my fix but breaks with libc6_2.6~20070518-2 unless it is applied. We might as well apply this fix to configure in the weeks to come since as soon as someone upgrades their libc they will break libgomp this way. -- Summary: Upgrading GNU/Linux to libc6_2.6~20070518-2 breaks libgomp make - FIX given Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgomp AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: rob1weld at aol dot com GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32193
