From 72b81552a1239f91054ae0c8469e6d780f79a890 Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Thu, 1 Jun 2017 10:56:10 -0400 Subject: Add shim header for bits/syscall.h. On Linux-based configurations, bits/syscall.h is a generated file. To avoid build-ordering problems, the Linux sys/syscall.h only includes bits/syscall.h if _LIBC is not defined. After the _ISOMAC-testsuite changes, this means any test case that includes sys/syscall.h tries to pull in bits/syscall.h. This would be fine, because it'll definitely have been generated by the time we start compiling tests, except that the generated /misc/bits/syscall.h is not visible in the include path, because nothing needed it till now. So we either get the bits/syscall.h from the host system, or the build fails. The fix is simple: add a shim header for bits/syscall.h. I put it in sysdeps/unix/sysv/linux/include instead of the top-level include/ because bits/syscall.h doesn't exist at all on other configurations as far as I can tell. This is known to affect nptl/tst-cond2[45]. Thanks to John David Anglin for noticing the problem.
