Its not honouring O= and requires that we first build libperf in the source tree, please fix this in a followup patch:
[acme@quaco perf]$ make -C tools/perf/lib clean make: Entering directory '/home/acme/git/perf/tools/perf/lib' CLEAN libperf CLEAN tests make: Leaving directory '/home/acme/git/perf/tools/perf/lib' [acme@quaco perf]$ ls -la tools/perf/lib/tests/ total 16 drwxrwxr-x. 2 acme acme 4096 Jul 25 07:35 . drwxrwxr-x. 4 acme acme 4096 Jul 25 07:35 .. -rw-rw-r--. 1 acme acme 857 Jul 25 07:34 Makefile -rw-rw-r--. 1 acme acme 328 Jul 25 07:34 test-cpumap.c [acme@quaco perf]$ make O=/tmp/build/perf -C tools/perf/lib/ tests make: Entering directory '/home/acme/git/perf/tools/perf/lib' LINK test-cpumap-a gcc: error: ../libperf.a: No such file or directory make[1]: *** [Makefile:22: test-cpumap-a] Error 1 make: *** [Makefile:115: tests] Error 2 make: Leaving directory '/home/acme/git/perf/tools/perf/lib' [acme@quaco perf]$
libperf itself is honouring O=:
[acme@quaco perf]$ make O=/tmp/build/perf -C tools/perf/lib make: Entering directory '/home/acme/git/perf/tools/perf/lib' LINK /tmp/build/perf/libperf.so.0.0.1 GEN /tmp/build/perf/libperf.pc make: Leaving directory '/home/acme/git/perf/tools/perf/lib' [acme@quaco perf]$ make O=/tmp/build/perf -C tools/perf/lib tests make: Entering directory '/home/acme/git/perf/tools/perf/lib' LINK test-cpumap-a gcc: error: ../libperf.a: No such file or directory make[1]: *** [Makefile:22: test-cpumap-a] Error 1 make: *** [Makefile:115: tests] Error 2 make: Leaving directory '/home/acme/git/perf/tools/perf/lib' [acme@quaco perf]$
Its only when I stop using O= that it works:
[acme@quaco perf]$ make -C tools/perf/lib make: Entering directory '/home/acme/git/perf/tools/perf/lib' HOSTCC fixdep.o HOSTLD fixdep-in.o LINK fixdep CC core.o CC cpumap.o CC threadmap.o CC evsel.o CC evlist.o CC zalloc.o CC xyarray.o CC lib.o LD libperf-in.o AR libperf.a LINK libperf.so.0.0.1 GEN libperf.pc make: Leaving directory '/home/acme/git/perf/tools/perf/lib' [acme@quaco perf]$ make O=/tmp/build/perf -C tools/perf/lib tests make: Entering directory '/home/acme/git/perf/tools/perf/lib' LINK test-cpumap-a LINK test-cpumap-so running static: - running test-cpumap.c...OK running dynamic: - running test-cpumap.c...OK make: Leaving directory '/home/acme/git/perf/tools/perf/lib' [acme@quaco perf]$
It is already useful albeit this limitation, so I'm applying.
