I tried to get the new glibc 2.16 working... make didn't fail, but at make check:
tests/dlfcn: Error 2
Didn't find any useful information about it.
I also installed it several times:
gives quite big libraries (libc smaller than libc-2.16, why that?)
../glibc/configure BUILD_CC='gcc' CC='gcc' --prefix=...
gives even bigger libraries, anyone know why?
Is there any special way (configuring) fedora (using F17) gets a small and fast library shipped by default?
../glibc/configure BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32' --prefix=...
-> make fails
I assume GCC needs a new libgcc to be able to not fail in this case, but trying to build gcc 4.7.1 with multilibs I get errors with incompatible libc!
Can x32 programs use more memory than 32-bit ones? I guess not due to limited pointer size.
