Fortran on QNX 6.2.x

We need to cross compile Fortran 77 from a Windows PC to
x86 QNX 6.2.x. Can anyone point me toward a QNX Fortran
cross compiler? Thanks.

QNX 6 doesn’t officially have a Fortran compiler.
But you should be able to build your own GNU Fortran compiler g77. Just download the QNX patched GCC source code from:
developers.qnx.com/Ports/Archive/

untar the source and take a look at the build-* scripts in root dir for configuration options. I believe you can just edit “build-nto” and change
–enable-languages=c++ to --enable-languages=c++,f77
