Uboot编译时出现个很奇怪的问题

编译前交叉编译器明明可用：

wangping@wangping:~/Desktop/linux/u-boot-1.2.0$ arm-linux-gcc -v
Using built-in specs.

Thread model: posix

wangping@wangping:~/Desktop/linux/u-boot-1.2.0$


编译时又提示arm-gcc-linux找不到：
make[1]: Leaving directory `/home/wangping/Desktop/linux/u-boot-1.2.0/tools'
make[1]: arm-linux-gcc: Command not found
make[1]: Entering directory `/home/wangping/Desktop/linux/u-boot-1.2.0/tools'
ln -s ../lib_generic/crc32.c crc32.c
gcc: crc32.c: No such file or directory
gcc: no input files

这里编译没有结束，我把它结束了。。编译十来分钟了还没结束

重新安装arm-gcc-linux
