Thanks for the quick reply. I had to comment the line with error.h in
your source in order to get a clean compile.
gcc -v
Using built-in specs.
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 3.4.4 [FreeBSD] 20050518
I've tried to load a big file (8gig) this is the output:
./test_mmap bigfile.iso
mmap error for input
Can you help me, what should I do next?
Thanks!
