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
