I also built the kernel/perf for crownbay and ran into the problem of bug #963, but got around that by pointing to a local clone of linux-yocto-2.6.37. Again, there was no problem with compile_perf and host infection. As I pointed out after the initial look, there does look like a problem with the perf Makefile hard-coding /usr/include/slang and /usr/include/elfutils, but there's no dependency in the perf recipe on libnewt/slang or elfutils - it skips those and builds without them if not found, and so far that's been the case and so those hard-coded paths haven't come into play. But it looks like with the recent addition of libnewt, perf sometimes does find the libnewt/slang pulled in by the unrelated chkconfig recipe, and at that point tries to use it, exposing the hard-coded /usr/include/slang. But since we now have libnewt available in the metadata, perf really should take advantage of it, so the hard-coded path should be fixed regardless, which I'll do. So I'll try adding the libnewt dependency for per, which should legitimately trigger the problem - I need to be able to trigger it somehow anyway in order to verify the fix. I'll also try getting perf to use elfutils, which is also available and should be getting used though it hasn't been so far, and is why the other hard-coded patch for elfutils hasn't come into play either. But note also that the slang recipe that libnewt depends on seems to have unrelated host contamination issues of its own, independent of perf. 13403 6 tom.zanussi 2011-04-25 11:14:48 +0000 Fixed by commit: ee2ff2ab53c4b26462fa2445b34c3ce09684a82c 13799 7 sgw 2011-05-13 10:53:42 +0000 Bernard: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=aa37762223fba8836f7a1ce09498fe7ac8851bdb 14931 8 sgw 2011-07-22 11:32:11 +0000 build works without host infection
