gvim7环境编译c代码的时候乱码

iuingeng

1. || /home/angus/Programing/hello.c: In function ????ain????
   
2. Programing/hello.c|15| warning: implicit declaration of function ????trerror????
   
3. Programing/hello.c|15| error: ????rrno????undeclared (first use in this function)
   
4. Programing/hello.c|15| error: (Each undeclared identifier is reported only once
   
5. Programing/hello.c|15| error: for each function it appears in.)

以上是编译信息，vim的其他地方均无乱码现象（可以输入中文，可以打开中文文件和显示中文目录）。只在编译信息这里出现乱码。
