The Fedora cross toolchains are only built to cross-compile kernels. It even says so right in the description: Description : Cross-build GNU C compiler. : : Only building kernels is currently supported. Support for : cross-building user space programs is not currently provided as : that would massively multiply the number of packages. I think you've hit an error in a usecase the toolchains don't even support. josh > I've reproduced this error in f28, f29.
