交叉编译环境的搭建

1. 下载交叉编译器

2. 安装交叉编译器

   sudo tar xvf cross-3.2.tar.bz2

   sudo mkdir /usr/local/arm

   sudo cp -R usr/local/arm/* /usr/local/arm

3. 配置环境变量

   sudo vim ~/.profile

   add the following in the end:

   export PATH=$PATH: /usr/local/arm

4. 使环境变量生效

   source ~/.profile

5. 检查路径设置

   echo $PATH

6. 测试

   ＃include

   int main(void)

   {

   printf("Hello, world!\n");

   return 0;

   }

   arm-linux-gcc -o hello hello.c
