Question

尝试使用Android的ADT Eclipse工具链构建静态NDK库。但是，每当我使用BUILD_STATIC_LIBRARY构建时，都不会产生输出：我收到消息

make: Nothing to be done for `all'."

有什么建议吗？

LOCAL_PATH          := $(call my-dir)
STL_PATH            := "C:/Android/ndk/sources/cxx-stl/gnu-libstdc++/4.6/include"
PLATFORM_INCLUDE    := "C:/Android/ndk/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi/include"
APP_STL             := gnustl_static

include $(CLEAR_VARS)

LOCAL_MODULE        := libCore
LOCAL_CPPFLAGS      += -std=c++11 -fexceptions -D_OS_ANDROID
LOCAL_LDLIBS        := -lGLESv2 -lEGL -lstdc++

LOCAL_C_INCLUDES    += $(LOCAL_PATH)/Headers
...

LOCAL_SRC_FILES     += Source/Engine/Game.cpp
...

include $(BUILD_STATIC_LIBRARY)

以下是来自Android NDK的两个libs示例项目的Android.mk文件的内容。

LOCAL_PATH:= $(call my-dir)

# first lib, which will be built statically
#
include $(CLEAR_VARS)

LOCAL_MODULE    := libtwolib-first
LOCAL_SRC_FILES := first.c

include $(BUILD_STATIC_LIBRARY)

# second lib, which will depend on and include the first one
#
include $(CLEAR_VARS)

LOCAL_MODULE    := libtwolib-second
LOCAL_SRC_FILES := second.c

LOCAL_STATIC_LIBRARIES := libtwolib-first

include $(BUILD_SHARED_LIBRARY)

您可以尝试将静态库构建为另一个共享库的一部分，如示例所示。

我刚刚对两个libs示例项目进行了ndk-build，我可以在 obj \ local \ armeabi 目录中看到.a文件和.so文件。

修改：默认情况下，ndk-build只会构建共享库和可执行文件，以及它们所依赖的模块。要强制构建，请在APP_MODULES中指定libCore，如下所示。

APP_MODULES := libCore

或在命令行中

ndk-build APP_MODULES=libCore

ADT工具链不为静态库生成输出
