Topic: Unknown weird compilation errors

I am trying to compile a program and am getting the following output in the build status window.

I understand the first couple, but then it all just goes into gobbledegook.

Any ideas what has gone wrong, what I need to do to fix it?

Re: Unknown weird compilation errors

Can you provide a bit more information?  What platform are you running on (Windows, macOS, Linux)?  What CPU are you using? 

What version of Simply Fortran are you currently running?

Did you recently upgrade Simply Fortran?

It would be helpful if you could share the source code with me at support@approximatrix.com, but I understand if that's not possible.
