gcc and executable file from Mac to Linux
 

good afternoon, this is probably not the right forum, but maybe someone already encountered the same problem; I wrote a NS solver in C on my mac, and used gcc-4.0 to compile it and it compiles nirmally and generates my working executable also. When I try to generate the same exe on a Linux machine, even if it compiles without any problem, once I execute the executable output, it does not do any of the calculations. Here is my makefile in case it can help. i hope someone can help me

thanks
