From 271402a3e97e3b9a4ce1e322a5f66c493122e1ec Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 12 Feb 2019 16:19:45 -0300 Subject: perf build: Add missing FEATURE_CHECK_LDFLAGS-libcrypto When the libcrypto feature test was added we forgot to add its FEATURE_CHECK_LDFLAGS pointing to the library needed to link with the test-all.bin feature test fast path binary, so even when it was introduced we got this: $ cat /tmp/build/perf/feature/test-all.make.output /usr/bin/ld: /tmp/ccjKeJJU.o: in function `main_test_libcrypto': /home/acme/git/perf/tools/build/feature/test-libcrypto.c:10: undefined reference to `MD5_Init' /usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libcrypto.c:11: undefined reference to `MD5_Update' /usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libcrypto.c:12: undefined reference to `MD5_Final' /usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libcrypto.c:14: undefined reference to `SHA1' collect2: error: ld returned 1 exit status $ cat /tmp/build/perf/feature/test-libcrypto. test-libcrypto.bin test-libcrypto.d test-libcrypto.make.output $ cat /tmp/build/perf/feature/test-libcrypto.make.output $ Fix it, so that we keep the fast path, which, at this point, will fail with the unwind-ARCH feature tests, that will be fixed in a followup patch: $ make -C tools/perf O=/tmp/build/perf ... libcrypto: [ on ] $ cat /tmp/build/perf/feature/test-all.make.output $ ldd /tmp/build/perf/feature/test-all.bin | grep libcrypto libcrypto.so.1.1 => /lib64/libcrypto.so.1.1 (0x00007f9892805000) $ $ grep libcrypto /tmp/build/perf/FEATURE-DUMP feature-libcrypto=1 $ With the unwind-ARCH tests fixed, we now finally manage to get test-all.bin built and linked with the features it tests, among them the ones fixed in this patchkit: $ ldd /tmp/build/perf/feature/test-all.bin | egrep 'unwind|crypto' libcrypto.so.1.1 => /lib64/libcrypto.so.1.1 (0x00007f95cf2b8000) libunwind-x86_64.so.8 => /lib64/libunwind-x86_64.so.8 (0x00007f95cf294000) libunwind.so.8 => /lib64/libunwind.so.8 (0x00007f95cf278000) $ Cc: Adrian Hunter Cc: Andi Kleen Cc: Carl Love Cc: David Ahern Cc: Jiri Olsa Cc: John McCutchan Cc: Namhyung Kim Cc: Pawel Moll Cc: Peter Zijlstra Cc: Sonny Rao Cc: Stephane Eranian Cc: Sukadev Bhattiprolu Fixes: 8ee4646038e4 ("perf build: Add libcrypto feature detection") Link: https://lkml.kernel.org/n/tip-rexc248jorf5b4l3qjn888cz@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/Makefile.config | 2 ++ 1 file changed, 2 insertions(+) (limited to 'tools/perf/Makefile.config') diff --git a/tools/perf/Makefile.config b/tools/perf/Makefile.config index 4b735042cad7..0f11d5891301 100644 --- a/tools/perf/Makefile.config +++ b/tools/perf/Makefile.config @@ -114,6 +114,8 @@ FEATURE_CHECK_LDFLAGS-libunwind-aarch64 = -lunwind -lunwind-aarch64 FEATURE_CHECK_LDFLAGS-libunwind-x86 = -lunwind -llzma -lunwind-x86 FEATURE_CHECK_LDFLAGS-libunwind-x86_64 = -lunwind -llzma -lunwind-x86_64 +FEATURE_CHECK_LDFLAGS-libcrypto = -lcrypto + ifdef CSINCLUDES LIBOPENCSD_CFLAGS := -I$(CSINCLUDES) endif -- cgit v1.2.3-59-g8ed1b
