aced:~/sy/crunch-3.6 # gcc -Wall -lm -pthread -std=c99 -m64 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 crunch.c -o crunch -lm
In file included from /usr/include/errno.h:36,
                 from crunch.c:250:
/usr/include/bits/errno.h:25:26: error: linux/errno.h: No such file or directory


查看下面文件是有的
aced:~/sy/crunch-3.6 # ls -l /usr/include/errno.h
-rw-r--r-- 1 root root 2452 2015-01-21 21:49 /usr/include/errno.h


/usr/include/bits/errno.h文件第25行

aced:~/sy/crunch-3.6 # head -30 /usr/include/bits/errno.h

自己搞定了!
把/usr/include/bits/errno.h第25行# include <linux/errno.h>
改成# include <errno.h>
就OK了
