{Android-编译FreeImage For Android}

最近要在一个Android项目里使用FreeImage库，所以移植到Android中 最麻烦的也是最核心的就是这个MakeFile，R5编译有问题，正好R6诞生了 编译的过程中出现了无法找到‘swab’方法的错误，有人提交了一个path解决了这个问题  http://www.crystax.net/trac/attachment/ticket/32/swab.patch 编译过程中遇到 lstdc++ 无法找到的情况，所以LIBRARIES就写死了：LIBRARIES =  -L $(SYSROOT)/usr/lib/ -lstdc++   include Makefile.srcs NDK_ROOT=/home/dino/android-ndk-r6 SYSROOT=$(NDK_ROOT)/platforms/android-8/arch-arm/ CC="$(NDK_ROOT)/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc" CXX="$(NDK_ROOT)/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-g++" # Converts cr/lf to just lf DOS2UNIX = dos2unix LIBRARIES =  -L $(SYSROOT)/usr/lib/ -lstdc++  MODULES = $(SRCS:.c=.o) MODULES := $(MODULES:.cpp=.o) CFLAGS ?= -O3 -fPIC -fexceptions -fvisibility=hidden -DNO_LCMS --sysroot=$(SYSROOT) CFLAGS += $(INCLUDE) CFLAGS += -nostdlib --sysroot=$(SYSROOT) -fno-short-enums  CFLAGS += -I"$(NDK_ROOT)/platforms/$(NDK_PLATFORM)/arch-arm/usr/include" -I"$(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/include/" -I"$(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/libs/armeabi/include" CFLAGS += -DANDROID CFLAGS += -march=armv7-a -mfloat-abi=softfp -mfpu=neon CXXFLAGS ?= -O3 -fPIC -fexceptions -fvisibility=hidden -Wno-ctor-dtor-privacy --sysroot=$(SYSROOT) CXXFLAGS += $(INCLUDE) CXXFLAGS += -nostdlib --sysroot=$(SYSROOT) -fno-short-enums  CXXFLAGS += -I"$(NDK_ROOT)/platforms/$(NDK_PLATFORM)/arch-arm/usr/include" -I"$(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/include/" -I"$(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/libs/armeabi/include" CXXFLAGS += -DANDROID CXXFLAGS += -march=armv7-a -mfloat-abi=softfp -mfpu=neon #ifeq ($(shell sh -c 'uname -m 2>/dev/null || echo not'),x86_64) # CFLAGS += -fPIC # CXXFLAGS += -fPIC #endif TARGET  = freeimage STATICLIB = lib$(TARGET).a SHAREDLIB = lib$(TARGET)-$(VER_MAJOR).$(VER_MINOR).so LIBNAME = lib$(TARGET).so VERLIBNAME = $(LIBNAME).$(VER_MAJOR) HEADER = Source/FreeImage.h default: all all: dist dist: FreeImage cp *.a Dist cp *.so Dist cp Source/FreeImage.h Dist dos2unix: @$(DOS2UNIX) $(SRCS) $(INCLS) FreeImage: $(STATICLIB) $(SHAREDLIB) .c.o: $(CC) $(CFLAGS) -c $< -o $@ .cpp.o: $(CXX) $(CXXFLAGS) -c $< -o $@ $(STATICLIB): $(MODULES) $(AR) r $@ $(MODULES) $(SHAREDLIB): $(MODULES) $(CC) -s -shared -Wl,-soname,$(VERLIBNAME) $(LDFLAGS) -o $@ $(MODULES) $(LIBRARIES) install: install -d $(INCDIR) $(INSTALLDIR) install -m 644 -o root -g root $(HEADER) $(INCDIR) install -m 644 -o root -g root $(STATICLIB) $(INSTALLDIR) install -m 755 -o root -g root $(SHAREDLIB) $(INSTALLDIR) ln -sf $(SHAREDLIB) $(INSTALLDIR)/$(VERLIBNAME) ln -sf $(VERLIBNAME) $(INSTALLDIR)/$(LIBNAME) ldconfig clean: rm -f core Dist/*.* u2dtmp* $(MODULES) $(STATICLIB) $(SHAREDLIB) $(LIBNAME)
