It's some combination of an ubuntu problem (not creating a a symlink for /usr/include/asm) and clang, not understanding you might want to compile for multiple architectures, so having the architecture independent stuff in another directory is better. With ubuntu you can get around the problem by installing gcc-multilib or symlinking usr/include/asm - Ali ----------------------------------------------------------- This is an automatically generated e-mail.
