Android ndk开发时查看编译器预定义宏

准备好c文件,命名为test.c，内容如下：

int main(void) {}

找到ndk安装目录下的arm-linux-androideabi-gcc.exe,并切换到此目录下，如我的路径为：

D:\Android\sdk\ndk-bundle\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-gcc.exe

执行命令：arm-linux-androideabi-gcc.exe -dM -E C:\Users\huweijian\Desktop\test.c
获得如下内容：
