Question

我正在尝试一个包含从源码构建的NDK库的基本Android应用。构建时出现以下错误：

gradlew assembleArm
:myapp:compileArmDebugNdk
make.exe: *** No rule to make target
`C:\Projects\MyApp\myapp\build\ndk\arm\debug\obj/local/armeabi-v7a/objs-debug/process/C_\Projects\MyApp\myapp\src\main\jni', needed by `C:\Projects\MyApp\myapp\build\ndk\arm\debug\obj/local/armeabi-v7a/objs-debug/process/C_\Projects\MyApp\myapp\src\main\jni\process.o'.  Stop.
:myapp:compileArmDebugNdk FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':myapp:compileArmDebugNdk'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    C:\android-ndk-r9d\ndk-build.cmd NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=C:\Projects\MyApp\myapp\build\ndk\arm\debug\Android.mk APP_PLATFORM=android-18 NDK_OUT=C:\Projects\MyApp\myapp\build\ndk\arm\debug\obj NDK_LIBS_OUT=C:\Projects\MyApp\myapp\build\ndk\arm\debug\lib NDK_DEBUG=1 APP_STL=stlport_static APP_ABI=armeabi-v7a

目标路径对我来说很奇怪。 gradle生成的makefile如下所示：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE := process
LOCAL_CFLAGS := -DANDROID_NDK
LOCAL_SRC_FILES := \
C:\Projects\MyApp\myapp\src\main\jni\process.cpp \

LOCAL_C_INCLUDES += C:\Projects\MyApp\myapp\src\main\jni
LOCAL_C_INCLUDES += C:\Projects\MyApp\myapp\src\arm\jni
LOCAL_C_INCLUDES += C:\Projects\MyApp\myapp\src\debug\jni
LOCAL_C_INCLUDES += C:\Projects\MyApp\myapp\src\armDebug\jni

include $(BUILD_SHARED_LIBRARY)

我正在使用

gradle plugin 0.9
适用于Windows x64的NDK r9d

我很感激任何帮助。我在gradle和GNU构建工具方面有一些经验，但我是Android和NDK的新手。

Answer 1

就像塞尔文说的那样，只要你添加另一个源文件就应该没问题了。即使是空洞的人也可以做到这一点。

我填写了一份错误报告，其中包含更多信息：https://code.google.com/p/android/issues/detail?id=66937

Answer 2

转到终端并写下

1：cd your_path_to \ src \ main \ jni

2：ndk-build

＆＃34;没有规则来制定目标＆＃34;使用Gradle在Windows上编译NDK源时
