fatal error: bits/libc-header-start.h: No such file or directory

使用arm-linux-gnueabi-gcc test.c 编译时提示fatal error: bits/libc-header-start.h: No such file or directory。

解决方法：
执行arm-linux-gnueabi-gcc -v

Using built-in specs.

打开 --includedir=/usr/arm-linux-gnueabi/include 这个路径，查看是否有bits/libc-header-start.h文件
如果没有，则安装libc的库

sudo apt install libc6-dev-armel-cross
