Android NDK示例编译错误：string.h：没有这样的文件或目录

Question

我试图编译Android ndk示例android-ndk-r6b/samples/hello-jni，我没有运气。

编译错误我得到的是：

$:/media/rober/android/android-ndk-r6b/samples/hello-jni$ 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/ 

我有我缺少一个环境变量或某种配置的感觉它告诉ndk在哪里查找string.h和jni.h文件，即使它们位于相同的ndk目录结构中，但我不确定会发生什么。

所有种类的技巧都是非常欢迎的。

Answer 1

编辑：我更新到R7和一切正常，很奇怪。

Answer 2

尝试

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

或

sudo find/-name string.h 

如果第一个将无法正常工作
