文章标签： android.mk 包含boost

在Android NDK环境下构建项目时遇到了链接错误，问题可能源于未正确包含共享/静态库。尽管指定了-lsomeLib，但缺少LOCAL_SHARED_LIBRARIES中的库，如libutils、libmedia等。Android.mk文件包含了多个库的引用，但在链接阶段仍然出现未定义的引用错误，例如针对libmedia.so的引用。这表明链接器无法找到必要的库文件。

Android NDK下构建项目时遇到问题.很可能是由于没有包括正确的共享/静态库.我添加的是-lsomeLib,但是没有包含LOCAL_SHARED_LIBRARIES的那些似乎…

我的Android.mk包含以下内容

LOCAL_SHARED_LIBRARIES = libutils libmedia libz libbinder

> ndk-build在哪里实际寻找这些图书馆？

>如果我不包括-lutils -lmedia -lz -lbinder,我甚至无法连接到链接器错误.我有一种感觉,包括只有-LsomeDir和-lsomeLib不是正确的方法来添加它们.

这是完整的Android.mk.

LOCAL_PATH := /Users/kevin/Desktop/player2/videoplayer/videoplayer/jni

LIBPLAYER_PATH := $(LOCAL_PATH)/../../LibPlayer

include $(CLEAR_VARS)

$(warning Android make file: $(LOCAL_PATH)/Android.mk)

$(warning Android sysroot: $(SYSROOT))

$(warning Additional LD_LIBS: $(LOCAL_PATH)/lib)

ifeq ($(BUILD_ID),MID)

LOCAL_CFLAGS += -DENABLE_FREE_SCALE

endif

LOCAL_MODULE := libamplayerjni

LOCAL_SRC_FILES := com_farcore_playerservice_AmPlayer.c sys_conf.c

LOCAL_ARM_MODE := arm

LOCAL_C_INCLUDES := $(LIBPLAYER_PATH)/amplayer/player/include \

LOCAL_LDLIBS := -L/Users/kevin/Desktop/player2/videoplayer/videoplayer/jni/lib -L$(SYSROOT)/usr/lib -llog -lz -lm -ldl **-lmedia -lstagefright -lutils -lbinder -lgcc -landroid -lc -lstdc++ -lthread_db**

**LOCAL_STATIC_LIBRARIES := libamplayer libamcodec libavformat libavcodec libavutil libamadec**

LOCAL_SHARED_LIBRARIES += libutils libmedia libz libbinder

LOCAL_PRELINK_MODULE := false

include $(BUILD_SHARED_LIBRARY)

许多错误之一与这些库有关(即libmedia.so).
