![]() When I did a compile of perf using a relative path for the output directory, the build failed when it tried to compile libtraceevent. This is because it continues to use the same relative path when the new working directory is in a different path. SUBDIR ../lib/traceevent/ /bin/sh: line 0: cd: ../../../nobackup/perf/: No such file or directory Makefile:74: *** output directory "../../../nobackup/perf/" does not exist. Stop. make: *** [../../../nobackup/perf///libtraceevent.a] Error 2 Make the path used an absolute path when building perf with O=. Boris: Teach Makefile to check whether the supplied O= directory exists and bail out if not. Reportedly, kernel dudes are idiots and need to be guarded so as not to shoot themselves in the foot when playing in the sandbox.
