I got some error messages when compiling examples provided by CPLEX on Red Hat Enterprise Linux Server release 6.1 64bits

Forgot to mention that the version of g++ is

[m8dd8@XXX static_pic]$ g++ -dumpversion
4.4.5

I missed the last two line in the error message:

collect2: ld returned 1 exit status
make: *** [ilodiet] Error 1

Sorry about that.

Problem solved, I used the wrong system makefile, it should be debian instead of sles...
