From a09e5967ad6819379fd31894634d7aed29c18409 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 12 Nov 2025 21:57:08 -0300 Subject: [PATCH] perf build: Don't fail fast path feature detection when binutils-devel is not available This is one more remnant of the BUILD_NONDISTRO series to make building with binutils-devel opt-in due to license incompatibility. In this case just the references at link time were still in place, which make building the test-all.bin file fail, which wasn't detected before probably because the last test was done with binutils-devel available, doh. Now: $ rpm -q binutils-devel package binutils-devel is not installed $ file /tmp/build/perf-tools/feature/test-all.bin /tmp/build/perf-tools/feature/test-all.bin: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=4b5388a346b51f1b993f0b0dbd49f4570769b03c, for GNU/Linux 3.2.0, not stripped $ Fixes: 970ae86307718c34 ("perf build: The bfd features are opt-in, stop testing for them by default") Reviewed-by: Ian Rogers Cc: Adrian Hunter Cc: James Clark Cc: Jiri Olsa Cc: Namhyung Kim Signed-off-by: Arnaldo Carvalho de Melo --- tools/build/feature/Makefile | 4 ++-- tools/perf/Makefile.config | 5 ++--- 2 files changed, 4 insertions(+), 5 deletions(-) diff --git a/tools/build/feature/Makefile b/tools/build/feature/Makefile index 49b0add392b1..95646290cb89 100644 --- a/tools/build/feature/Makefile +++ b/tools/build/feature/Makefile @@ -107,7 +107,7 @@ all: $(FILES) __BUILD = $(CC) $(CFLAGS) -MD -Wall -Werror -o $@ $(patsubst %.bin,%.c,$(@F)) $(LDFLAGS) BUILD = $(__BUILD) > $(@:.bin=.make.output) 2>&1 BUILD_BFD = $(BUILD) -DPACKAGE='"perf"' -lbfd -ldl - BUILD_ALL = $(BUILD) -fstack-protector-all -O2 -D_FORTIFY_SOURCE=2 -ldw -lelf -lnuma -lelf -lslang $(FLAGS_PERL_EMBED) $(FLAGS_PYTHON_EMBED) -DPACKAGE='"perf"' -lbfd -ldl -lz -llzma -lzstd + BUILD_ALL = $(BUILD) -fstack-protector-all -O2 -D_FORTIFY_SOURCE=2 -ldw -lelf -lnuma -lelf -lslang $(FLAGS_PERL_EMBED) $(FLAGS_PYTHON_EMBED) -ldl -lz -llzma -lzstd __BUILDXX = $(CXX) $(CXXFLAGS) -MD -Wall -Werror -o $@ $(patsubst %.bin,%.cpp,$(@F)) $(LDFLAGS) BUILDXX = $(__BUILDXX) > $(@:.bin=.make.output) 2>&1 @@ -115,7 +115,7 @@ __BUILDXX = $(CXX) $(CXXFLAGS) -MD -Wall -Werror -o $@ $(patsubst %.bin,%.cpp,$( ############################### $(OUTPUT)test-all.bin: - $(BUILD_ALL) || $(BUILD_ALL) -lopcodes -liberty + $(BUILD_ALL) $(OUTPUT)test-hello.bin: $(BUILD) diff --git a/tools/perf/Makefile.config b/tools/perf/Makefile.config index 5700516aa84a..2dd5f5a60568 100644 --- a/tools/perf/Makefile.config +++ b/tools/perf/Makefile.config @@ -354,9 +354,6 @@ FEATURE_CHECK_LDFLAGS-libpython := $(PYTHON_EMBED_LDOPTS) FEATURE_CHECK_LDFLAGS-libaio = -lrt -FEATURE_CHECK_LDFLAGS-disassembler-four-args = -lbfd -lopcodes -ldl -FEATURE_CHECK_LDFLAGS-disassembler-init-styled = -lbfd -lopcodes -ldl - CORE_CFLAGS += -fno-omit-frame-pointer CORE_CFLAGS += -Wall CORE_CFLAGS += -Wextra @@ -930,6 +927,8 @@ ifdef BUILD_NONDISTRO ifeq ($(feature-libbfd), 1) EXTLIBS += -lbfd -lopcodes + FEATURE_CHECK_LDFLAGS-disassembler-four-args = -lbfd -lopcodes -ldl + FEATURE_CHECK_LDFLAGS-disassembler-init-styled = -lbfd -lopcodes -ldl else # we are on a system that requires -liberty and (maybe) -lz # to link against -lbfd; test each case individually here -- 2.47.3
