Revision 167815 changes HW_NCPU to HW_AVAILCPU, which causes build failure on FreeBSD with the following message: /home/lantw44/gnome/source/webkit-trunk/Source/WTF/wtf/NumberOfCores.cpp:56:13: error: use of undeclared identifier 'HW_AVAILCPU' HW_AVAILCPU ^ /home/lantw44/gnome/source/webkit-trunk/Source/WTF/wtf/NumberOfCores.cpp:58:43: error: invalid application of 'sizeof' to an incomplete type 'int []' int sysctlResult = sysctl(name, sizeof(name) / sizeof(int), &result, &length, 0, 0); ^~~~~~ 2 errors generated. I run `grep -r HW_AVAILCPU /usr/include` on FreeBSD, NetBSD, OpenBSD, and there is no HW_AVAILCPU.

Created attachment 230810 [details] Patch It looks like it should be done using sysconf() as well, like we do in Linux: http://www.freebsd.org/cgi/man.cgi?query=sysconf&sektion=3&n=1 http://www.openbsd.org/cgi-bin/man.cgi?query=sysconf&sektion=3&format=html http://netbsd.gw.com/cgi-bin/man-cgi?sysconf++NetBSD-current Can someone try this patch?
