Hi! I tried to build GCC 4.2 (core and g++) on my linux box (Ubuntu 7.04, amd64). Except a program-suffix and an install prefix, I used no configure options. Building failed with the following messages: > [...] > checking for x86_64-unknown-linux-gnu-gcc... /home/alexx/tmp/gcc-build/./gcc/xgcc -B/home/alexx/tmp/gcc-build/./gcc/ -B/home/alexx/local/gcc/x86_64-unknown-linux-gnu/bin/ -B/home/alexx/local/gcc/x86_64-unknown-linux-gnu/lib/ -isystem /home/alexx/local/gcc/x86_64-unknown-linux-gnu/include -isystem /home/alexx/local/gcc/x86_64-unknown-linux-gnu/sys-include -m32 > checking for C compiler default output file name... a.out > checking whether the C compiler works... configure: error: cannot run C compiled programs. > If you meant to cross compile, use `--host'. > See `config.log' for more details. > make[1]: *** [configure-target-libmudflap] Error 1 > make[1]: Leaving directory `/home/alexx/tmp/gcc-build' > make: *** [all] Error 2 Has anyone an idea why GCC is obviously unable to produce runnable C programs in my configuration?
