Public bug reported: Binary package hint: linux-libc-dev
linux-libc-dev provides /usr/include/asm/atomic.h, which includes the CPU-appropriate asm-${ARCH}/atomic.h file. /usr/include/asm-x86_64/atomic.h includes <asm/alternative.h> (apparently just to get the definition of LOCK_PREFIX), which is missing. How to reproduce: Compile a file containing just #include <asm/atomic.h> using gcc -c filename.c. ** Affects: linux-source-2.6.17 (Ubuntu) Importance: Untriaged Status: Unconfirmed -- asm*/alternative.h missing on x86-64 https://launchpad.net/bugs/57521 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
