The problem could be noticed by calling: make -C tools/perf feature-dump That would end up misdetecting the feature-compile-x32, that, building using 'gcc -mx32' needs stub headers not present in a fedora 23 devel machine and thus fail to compile, but ended up appearing as detected, i.e. present in tools/perf/FEATURE-DUMP as 'feature-compile-x32=1'. With this fix it correctly appears as 'feature-compile-x32=0' and if we uninstall the libc devel files for 32 bits (glibc-devel.i686), then the relevant variable is flipped from 'feature-compile-32=1' to 'feature-compile-32=0'. The same things happened for bionic and libbabeltrace, that were misdetected because the are no tested in test-all.c Reported-and-Tested-by: Arnaldo Carvalho de Melo Signed-off-by: Jiri Olsa Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-u0sjaddf1r9m8icpd98ry7fz@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/build/Makefile.feature | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/tools/build/Makefile.feature b/tools/build/Makefile.feature index 674c47d5f9d1..7bff2ea831cf 100644 --- a/tools/build/Makefile.feature +++ b/tools/build/Makefile.feature @@ -119,6 +119,14 @@ ifeq ($(feature-all), 1) # test-all.c passed - just set all the core feature flags to 1: # $(foreach feat,$(FEATURE_TESTS),$(call feature_set,$(feat))) + # + # test-all.c does not comprise these tests, so we need to + # for this case to get features proper values + # + $(call feature_check,compile-32) + $(call feature_check,compile-x32) + $(call feature_check,bionic) + $(call feature_check,libbabeltrace) else $(foreach feat,$(FEATURE_TESTS),$(call feature_check,$(feat))) endif -- 2.5.0
