cramfs-1.1/mkcramfs.c:446: undefined reference to `minor'

在编译cramfs-1.1时报如下错误：

/usr/bin/ld: /tmp/ccMb5KDC.o: in function `print_node':
/root/cramfs-1.1/mkcramfs.c:446: undefined reference to `minor'
/usr/bin/ld: /root/cramfs-1.1/mkcramfs.c:446: undefined reference to `major'
collect2: error: ld returned 1 exit status
make: *** [<builtin>: mkcramfs] Error 1

解决办法：

在mkcramfs.c里包含如下头文件：

#include <sys/sysmacros.h>
