The 32-bit compiler can't build 64-bit binaries. Doesn't matter that your cpu is 64-bit if you're running it in 32-bit mode. Apparently, the 32-bit compiler *can* somehow be made to build 64-bit binaries too, but the Fedora gcc isn't set up for it. > Any ideas how is this going to work with qemu? Very slowly? > What should I install? Any cross-compilers? I'd just install x86_64 Fedora. Not aware of anyone packaging a cross-compiler for x86_64 builds on i686. Most people just run x86_64 if they want to build both x86_64 and i686. -- Jarod Wilson jarod@xxxxxxxxxx -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
