Subject: mmap installation failure

Hi, all~

I am struggling to mmap a file using ruby. But some errors occurred
while installing the knu-ruby-mmap and I don't know what's going on.
The error information are as follows:

compiling mmap.c

make: *** [mmap.o] Error 1

Has anyone try this before？
Or are there any other methods recommended to do "mmap"?

Thanks
