我最开始创建的是共享库,但我认为创建一个共享库和其余静态库会更有效率。当所有库都是共享的时候,编译和链接都没问题,但是当转为静态库后,我在链接时遇到了“未定义引用”的问题。
编辑: 我在一个 Android.mk
中构建所有库。
Android.mk:
MY_LOCAL_PATH := $(call my-dir)
MY_LOCAL_CFLAGS := -DDEBUG
TARGET_PLATFORM := 'android-4'
LOCAL_PATH := $(MY_LOCAL_PATH)/../../Base
include $(CLEAR_VARS)
LOCAL_MODULE := Base
LOCAL_SRC_FILES := <Base src files>
include $(BUILD_STATIC_LIBRARY)
MY_LOCAL_STATIC_LIBRARIES := Base
MY_LOCAL_C_INCLUDES := $(MY_LOCAL_PATH)/../../Base
LOCAL_PATH := $(MY_LOCAL_PATH)/../../Framework
include $(CLEAR_VARS)
LOCAL_MODULE := Framework
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)
LOCAL_SRC_FILES := <Framework src files>
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
include $(BUILD_STATIC_LIBRARY)
MY_LOCAL_STATIC_LIBRARIES += Framework
MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/../../Framework
LOCAL_PATH := $(MY_LOCAL_PATH)/Graphics
include $(CLEAR_VARS)
LOCAL_MODULE := Graphics
LOCAL_SRC_FILES := <Graphics src files>
LOCAL_EXPORT_LDLIBS := -lGLESv1_CM
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)
include $(BUILD_STATIC_LIBRARY)
MY_LOCAL_STATIC_LIBRARIES += Graphics
MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/Graphics
LOCAL_PATH := $(MY_LOCAL_PATH)/Platform
include $(CLEAR_VARS)
LOCAL_MODULE := Platform
LOCAL_SRC_FILES := <Platform src files>
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)
include $(BUILD_STATIC_LIBRARY)
MY_LOCAL_STATIC_LIBRARIES += Platform
MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/Platform
LOCAL_PATH := $(MY_LOCAL_PATH)
include $(CLEAR_VARS)
LOCAL_MODULE := Final
LOCAL_SRC_FILES := <Final src files>
LOCAL_STATIC_LIBRARIES := $(MY_LOCAL_STATIC_LIBRARIES)
LOCAL_LDLIBS := -llog
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)
include $(BUILD_SHARED_LIBRARY)
ndk-build V=1 -B
的最后一行:

编辑2: TextureRenderer在Graphics中,并已包含。
有人知道为什么它可能不起作用以及如何修复吗?
