Question

我正在尝试编译Android ndk示例android-ndk-r6b / samples / hello-jni，我没有运气。

我得到的编译错误是：

 $:/media/rober/android/android-ndk-r6b/samples/hello-jni$ ndk-build
    Gdbserver      : [arm-linux-androideabi-4.4.3] libs/armeabi/gdbserver
    Gdbsetup       : libs/armeabi/gdb.setup
    Compile thumb  : hello-jni &lt= hello-jni.c
    /media/rober/android/android-ndk-r6b/samples/hello-jni/jni/hello-jni.c:17:20: error: string.h: No such file or directory
    /media/rober/android/android-ndk-r6b/samples/hello-jni/jni/hello-jni.c:18:17: error: jni.h: No such file or directory
    /media/rober/android/android-ndk-r6b/samples/hello-jni/jni/hello-jni.c:27: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'Java_com_example_hellojni_HelloJni_stringFromJNI'
    make: *** [/media/rober/android/android-ndk-r6b/samples/hello-jni/obj/local/armeabi/objs-debug/hello-jni/hello-jni.o] Error 1

        /media/rober/android/android-sdk-linux_86/tools:
        /media/rober/android/android-ndk-r6b/

我觉得我错过了一个环境变量或某种配置，告诉ndk在哪里查找string.h和jni.h文件，即使它们在同一个ndk目录结构中，但我不确定会发生什么。

非常欢迎各种提示：）

Answer 1

编辑：我更新到r7，一切正常，很奇怪。

Answer 2

尝试

find /media/rober/android/ -name string.h

或

sudo find / -name string.h

如果第一个不起作用

Android NDK示例编译错误：string.h：没有这样的文件或目录
