Hello, after having switched from --disable--multilib to enable it (we actually need it), on one machine I get checking whether the gcc -m32 linker (/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld -m elf_x86_64 -m elf_i386) supports shared libraries... yes checking whether -lc should be explicitly linked in... no checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES. make[3]: *** [configure-stage1-zlib] Error 1 make[3]: Leaving directory `/home/csoliver/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2_build' I find a discussion on a similar problem at http://www.listware.net/201012/gcc-gcc/71297-libquadmath-configure-error-link-tests-are-not-allowed-after-gccnoexecutables.html which ends in apparently saying that there is a gcc-bug which was not fixed for 4.5.2, then proposing a work-around, but where this work-around doesn't appear in that e-mail :=((( The above error concerns zlib (why is this? zlib is not mentioned as a prerequisite?), so it might be different. The configuration data is (as I said, with --disable-multilib is worked on that machine (though without java), while enable-multilib works on other machines --prefix=/home/csoliver/OKplatform/ExternalSources/Installations/Gcc/4.5.2 --enable-languages=c,c++,fortran,java --enable-threads=posix --enable-shared --enable-multilib > gcc --version gcc (SUSE Linux) 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036] > uname -a Linux cs-oksvr 2.6.25.20-0.1-default #1 SMP 2008-12-12 20:30:38 +0100 x86_64 x86_64 x86_64 GNU/Linux Hope somebody can help here (Tobias Burnus, as mentioned in the above thread?); it's quite a thorny issue to install 4.5.2.
