GAMS Solaris 64 bit problem

This means you are missing Fortran run time support. A client of mine had the same problem when I sold him a GAMS system for Solaris 64-bit SPARC. In this case you try to run the CONOPT solver, which is written in Fortran. It is dynamically linked and therefore needs some run time libraries. If you don't have a Fortran compiler installed on your system you may get this error. Software suppliers are allowed to provide these files. The GAMS web site actually does provide a download for the 32-bit runtime here. Unfortunately for 64 bit no such download is provided. You can contact GAMS support to request the 64 bit Fortran run time libraries.
