Hello everybody,

I have a compilation problem using gcc. I'm using a 64 bit machine with ubuntu. I use the callable library for a fortran code. At the end of the compilation i'm getting the following output:

I got the same type of errors at the compilation of some of the fortran and c routines, but i manage to go around them through the mcmodel flag. The interface for the cplex function are performed through an fcallc.c routine, also i use the check.c routine.

My machine is running on Ubuntu 10.04 x86-64, and the version of gcc is 4.4.3.

I apollogise for my english.

Thanks in advance.

I am not a Fortran programmer/expert at all. A very wild guess from the error messages is that maybe the problem goes away if you use 32bit library of CPLEX.

I am not a FORTRAN expert either. Here are a few things I can think of:
1. Have you tried to use -fPIC flag?
2. The libraries you are using are meant for GCC 4.1. Maybe you can try to use GCC 4.1 and see if that reduce the number of errors.
