我正在尝试在我的 swing 项目中包含一个C++库。
当我使用 stdio.h 编译 jnilib/so 时，它可以正常工作：
gcc -shared -o libhello.jnilib hello.c -fPIC -I/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/include -I/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/include/darwin
我正在尝试导入并需要使用 gnu-libstdc++/4.9如何链接我的 Java 项目？
当我尝试构建 jni 文件时：
It will throw this:
test.c:5:10: fatal error: 'string' file not found
#include <string>

现在，当我链接到此内容时：
-I /Users/tnuwin/Documents/ndk/android-ndk-r12b/sources/cxx-stl/gnu-libstdc++/4.9/libs/x86_64/include
它会抛出此错误：

添加-I /Users/timnuwin/Documents/ndk/android-ndk-r12b/platforms/android-17/arch-x86/usr/include后，现在它会抛出：

该cmd能够创建我的jnilib文件。 :D3天后呵呵
