Update the Makefile to support cross-compiling for Android. The original ideea for this was send by Bernhard Rosenkraenzer in https://lkml.org/lkml/2012/8/23/316, but this is a rewrite. Changes: () support bionic in addition to glibc () remove rt and pthread libraries that do not exist in Android () use $(CFLAGS) when detecting initial compiler flags. This is needed when setting CFLAGS as an argument of make (e.g. for setting --sysroot). () include perf's local directory when building for Android to be able to find relative paths if using --sysroot (e.g.: ../../include/linux/perf_event.h) Signed-off-by: Bernhard Rosenkraenzer Signed-off-by: Irina Tirdea --- tools/perf/Makefile | 25 +++++++++++++++++++------ tools/perf/config/feature-tests.mak | 9 +++++++++ 2 files changed, 28 insertions(+), 6 deletions(-) diff --git a/tools/perf/Makefile b/tools/perf/Makefile index 0e468b5..1a23118 100644 --- a/tools/perf/Makefile +++ b/tools/perf/Makefile @@ -155,15 +155,15 @@ SPARSE_FLAGS = -D__BIG_ENDIAN__ -D__powerpc__ -include config/feature-tests.mak -ifeq ($(call try-cc,$(SOURCE_HELLO),-Werror -fstack-protector-all),y) +ifeq ($(call try-cc,$(SOURCE_HELLO),$(CFLAGS) -Werror -fstack-protector-all),y) CFLAGS := $(CFLAGS) -fstack-protector-all endif -ifeq ($(call try-cc,$(SOURCE_HELLO),-Werror -Wstack-protector),y) +ifeq ($(call try-cc,$(SOURCE_HELLO),$(CFLAGS) -Werror -Wstack-protector),y) CFLAGS := $(CFLAGS) -Wstack-protector endif -ifeq ($(call try-cc,$(SOURCE_HELLO),-Werror -Wvolatile-register-var),y) +ifeq ($(call try-cc,$(SOURCE_HELLO),$(CFLAGS) -Werror -Wvolatile-register-var),y) CFLAGS := $(CFLAGS) -Wvolatile-register-var endif @@ -172,6 +172,13 @@ endif BASIC_CFLAGS = -Iutil/include -Iarch/$(ARCH)/include -I$(OUTPUT)util -I$(TRACE_EVENT_DIR) -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE BASIC_LDFLAGS = +ifeq ($(call try-cc,$(SOURCE_BIONIC),$(CFLAGS)),y) + BIONIC := 1 + EXTLIBS := $(filter-out -lrt,$(EXTLIBS)) + EXTLIBS := $(filter-out -lpthread,$(EXTLIBS)) + BASIC_CFLAGS += -I. +endif + # Guard against environment variables BUILTIN_OBJS = LIB_H = @@ -467,12 +474,18 @@ else FLAGS_LIBELF=$(ALL_CFLAGS) $(ALL_LDFLAGS) $(EXTLIBS) ifneq ($(call try-cc,$(SOURCE_LIBELF),$(FLAGS_LIBELF)),y) FLAGS_GLIBC=$(ALL_CFLAGS) $(ALL_LDFLAGS) - ifneq ($(call try-cc,$(SOURCE_GLIBC),$(FLAGS_GLIBC)),y) - msg := $(error No gnu/libc-version.h found, please install glibc-dev[el]/glibc-static); - else + ifeq ($(call try-cc,$(SOURCE_GLIBC),$(FLAGS_GLIBC)),y) + LIBC_SUPPORT := 1 + endif + ifeq ($(BIONIC),1) + LIBC_SUPPORT := 1 + endif + ifeq ($(LIBC_SUPPORT),1) NO_LIBELF := 1 NO_DWARF := 1 NO_DEMANGLE := 1 + else + msg := $(error No gnu/libc-version.h found, please install glibc-dev[el]/glibc-static); endif else FLAGS_DWARF=$(ALL_CFLAGS) -ldw -lelf $(ALL_LDFLAGS) $(EXTLIBS) diff --git a/tools/perf/config/feature-tests.mak b/tools/perf/config/feature-tests.mak index eaeb0fd..3ef5ec9 100644 --- a/tools/perf/config/feature-tests.mak +++ b/tools/perf/config/feature-tests.mak @@ -43,6 +43,15 @@ int main(void) } endef +define SOURCE_BIONIC +#include + +int main(void) +{ + return __ANDROID_API__; +} +endef + define SOURCE_ELF_MMAP #include int main(void) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
