I've been having problems building a cross compiler for a s390x-suse-linux system running SLES8 from a i686-redhat-linux system running Redhat 7.1
I made ones for SLES7 and SLES8 on the s390 that work just fine. I'm assuming it's some 64bit/biarch issue. binutils builds just fine. I've tried getting the includes and libraries from both the CD and from a running s390x-suse-linux system. I'm applying all the s390x patches for gcc that come in the source rpm on the SLES8 CD. Most recently, I configured gcc with # ./configure --enable-threads=posix --prefix=/usr/local --enable-languages=c,c++,f77,objc --disable-libgcj --with-system-zlib --enable-shared --enable-__cxa_atexit --target=s390x-suse-linux i686-pc-linux-gnu which looks like what the rpm spec file wants. When I make it, I run into a couple issues. First, I get errors like this /usr/local/s390x-suse-linux/bin/ld: skipping incompatible /usr/local/s390x-suse-linux/lib64/libc.so.6 when searching for /usr/local/s390x-suse-linux/lib64/libc.so.6 /usr/local/s390x-suse-linux/bin/ld: cannot find /usr/local/s390x-suse-linux/lib64/libc.so.6 collect2: ld returned 1 exit status make[2]: *** [32/libgcc_s_32.so] Error 1 make[2]: Leaving directory `/usr/src/redhat/BUILD/gcc-3.2/gcc' make[1]: *** [stmp-multilib] Error 2 make[1]: Leaving directory `/usr/src/redhat/BUILD/gcc-3.2/gcc' make: *** [all-gcc] Error 2 this all depends on what I have in /usr/local/s390x-suse-linux/lib/libc.so If keep switching back and forth between GROUP ( /usr/local/s390x-suse-linux/lib/libc.so.6 /usr/local/s390x-suse-linux/li b/libc_nonshared.a ) and GROUP ( /usr/local/s390x-suse-linux/libi64/libc.so.6 /usr/local/s390x-suse-linux /libi64/libc_nonshared.a ) I can make it most of the way through compiling, although I'm sure this isn't the correct thing to do, and it's probably related to my other problem. Eventaully I get this error checking whether the C compiler (/usr/src/redhat/BUILD/gcc-3.2/gcc/xgcc -B/usr/src/redhat/BUILD/gcc-3.2/gcc/ -B/usr/local/s390x-suse-linux/bin/ -B/usr/local/s390x-suse-linux/lib/ -isystem /usr/local/s390x-suse-linux/include -g -O2 ) works... no configure: error: installation or configuration problem: C compiler cannot create executables. make: *** [configure-target-libiberty] Error 1 And I can't get any further. Any ideas. Is there something I need to do with the ld scripts to make a cross compiler for a biarch system? Thanks. -Ben Benjamin E. Marzinski [EMAIL PROTECTED]
