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>
- undefined reference mkcramfs cramfs minorundefined reference mkcramfs cramfs undefined_reference_to_xxx preloader undefined reference ubuntu undefined_reference_to_xxx undefined reference undefined reference int add undefined reference cmake xxx imp_wsacleanup wsacleanup undefined reference undefined reference winmain 39 event_handler undefined reference typeinfo undefined reference collect2 returned
