I don't know if Compaq Fortran tool provides you that option (i.e. What you could try is to not use the incremental linking as suggested. The Fortran compiler would produce the same object file format for the Linker to recognise it. So assuming it is a Microsoft Linker, this is the error message People accused/criticised Microsoft abusing its dominant position in the x86-based desktop with Windows and Office but without the Linker tool from Microsoft, one can't create an executable regardless if the programming language is Fortran, C/C++, assembly or any other unless the language development tool provider write their own Linker. But I know Microsoft licensed out their Linker tool for other language compiler and development tools makers to use in the past (don't know about now). Sorry for being pedantic, but it looks like you have a Linker error and not a Compiler error. I know I could continue to use VirtualBox just for this Fortran compiler, but I prefer VMWare and I have a VMWare VM with other old software already set up for the purpose. I even tried converting the VirtualBox VM to VMWare via an ova file, but that produced the same errors. And the resulting programs run OK within the VMWare VM. I have the same installation of Fortran/Win XP in a VirtualBox VM and it runs without a problem. The same program on the host it says that the program cannot run on 64bit Windows. With a simple program not linking to a library, trying to run the compiled program from a command prompt within the VM says ' Program too big to fit in memory'. Yesterday, I wanted to update a program but I now find it does not compile correctly when linking to a library, reporting ' fatal error LNK1123: failure during conversion to COFF'.

The last time I did this was in January 2014. I used Compaq Visual Fortran 6.6c VMWare Player through to VMWare Workstation in a Windows XP VM for many years to produce programs that run at the command prompt.
