Problem with using Gurobi in Netbeans

[王志航]

Hello, I'm a stater to use Gurobi in windows. My development environment is Netbeans. I try to copy the code of mip1_c.c, and also the header file gurobi_c.h. But, after building the project, there are some error messages which are shown below. Can anybody tell me how can I fix it? Thanks

Are you using a 64-bit version of Gurobi and a 64-bit C-Compiler (e.g. this one)?

[王志航]

Yes

I use cygwin64 and netbeans IDE7.4. I think its the problem of path setting or including, but i have not had any idea to solve it.

These are linker errors, not compiler errors. So the include paths should not be the problem.

I never used Cygwin64. So I don't know whether this is compatible. I can only tell you that it works with the MinGW-Verison I posted above.
