NDK环境搭建-windows篇        http://www.jianshu.com/p/708e6bf68ae9    2. Mistake in documentation/error message?        https://github.com/android-ndk/ndk/issues/264    3. 编译一个模块时出现undefined reference to `__android_log_print‘         http://bbs.csdn.net/topics/360020076二、error：    1. 错误1：        1. 错误现象：            D:\zengjf\SourceCode\Android\android_app\Test>ndk-build            C:/Users/zengjf/AppData/Local/Android/Sdk/ndk-bundle/build//../build/core/build-binary.mk:687: Android NDK: Module zengjf depends on undefined modules: android_runtime nativehelper cutils utils log            C:/Users/zengjf/AppData/Local/Android/Sdk/ndk-bundle/build//../build/core/build-binary.mk:701: *** Android NDK: Aborting (set APP_ALLOW_MISSING_DEPS=true to allow missing dependencies)    .  Stop.            D:\zengjf\SourceCode\Android\android_app\Test>        2. 解决方法            1. C:\Users\zengjf\AppData\Local\Android\Sdk\ndk-bundle\build\core\build-binary.mk            2. 修改内容：                ...                ifdef undefined_libs                    $(call __ndk_warning,Module $(LOCAL_MODULE) depends on undefined modules: $(undefined_libs))                    # https://github.com/android-ndk/ndk/issues/208                    # ndk-build didn‘t used to fail the build for a missing dependency. This                    # seems to have always been the behavior, so there‘s a good chance that                    # there are builds out there that depend on this behavior (as of right now,                    # anything using libc++ on ARM has this problem because of libunwind).                    #                    # By default we will abort in this situation because this is so completely                    # broken. A user may define APP_ALLOW_MISSING_DEPS to "true" in their                    # Application.mk or on the command line to revert to the old, broken                    # behavior.                    APP_ALLOW_MISSING_DEPS=true    // add this line                     ifneq ($(APP_ALLOW_MISSING_DEPS),true)                        $(call __ndk_error,Aborting (set APP_ALLOW_MISSING_DEPS=true to allow missing dependencies))                    endif                endif                ...    2. 错误2：        1. 错误现象：            undefined references to `__android_log_print‘ follow        2. 解决方法：            Android.mk文件中加入LOCAL_LDLIBS += -llog即可
