Current "" cannot detect "sys/cpuset.h" even if it exists on FreeBSD 9.1:

checking sys/cpuset.h presence... yes
configure: WARNING: sys/cpuset.h: present but cannot be compiled
configure: WARNING: sys/cpuset.h:     check for missing prerequisite headers?
configure: WARNING: sys/cpuset.h: see the Autoconf documentation
configure: WARNING: sys/cpuset.h:     section "Present But Cannot Be Compiled"
configure: WARNING: sys/cpuset.h: proceeding with the compiler's result
configure: WARNING:     ## ----------------------------------------------- ##
configure: WARNING:     ## Report this to ##
configure: WARNING:     ## ----------------------------------------------- ##
checking for sys/cpuset.h... no

This is because sys/param.h should be included in the test.

What stops merging this patch?

I think probably people want to test the patch independently and make sure it works, but I don't have a BSD box handy for that :(

Question about a hunk:

+AC_CHECK_HEADERS([sys/cpuset.h], [], [],
+# include <sys/param.h>

What is going on here?

comment:5 Changed 5 years ago by kazu-yamamoto

Manpage of cpuset_getaffinity() says:

#include <sys/param.h>
#include <sys/cpuset.h>

This bug happens because the check program only includes sys/cpuset.h. The patch first checks whether or not sys/param.h exist. If exists, check whether or not sys/cpuset.h exist with sys/param.h included.
