Certain feature tests fail with link errors: triton:~/tip/tools/perf/config/feature-checks> make test-libbabeltrace.bin gcc -MD -o test-libbabeltrace.bin test-libbabeltrace.c # -lbabeltrace provided by /tmp/cc6dRSqd.o: In function `main': test-libbabeltrace.c:(.text+0xf): undefined reference to `bt_ctf_stream_class_get_packet_context_type' although they should already fail with a build error due to lack of a proper prototype for the function. Due to this I first tried to find which library was missing - while it was the whole feature that was missing from the .h file already. To solve this, propagate -Wall -Werror to all testcases and remove them from testcase Makefile rules that used them explicitly. A missing feature now outputs: triton:~/tip/tools/perf/config/feature-checks> make test-libbabeltrace.bin gcc -MD -Wall -Werror -o test-libbabeltrace.bin test-libbabeltrace.c # -lbabeltrace provided by test-libbabeltrace.c: In function ‘main’: test-libbabeltrace.c:6:2: error: implicit declaration of function ‘bt_ctf_stream_class_get_packet_context_type’ [-Werror=implicit-function-declaration] Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: David Ahern <david.ahern@oracle.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20150228091627.GF31887@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
