G77 exe doesn't run

[GerritGroot]

Maybe this is not the right forum for it. But I installed cygwin to compile with g77, but once I run the executable it gives me an error that "cygwin1.dll" is missing. However, this file is perfectly installed, even if I place it in the same directory as my "main.exe" it says it's missing.

Any ideas of what I did wrong during the compilation with g77?

Thanks,

Gerrit

Make sure cygwin1.dll is in the same directory as g77.exe
This is for Force but the contents should look something similar to this

Yes, cygwin1.dll was in the same directory. It got there when I installed cygwin. However, I got some old versions of cygwin as well in other places that were included in the path, I'll delete those first.

Having multiple versions of cygwin1.dll can be a pain. I'm running 5 different versions: cygwin, ssh, gcc, g77 and g95. I gave up trying to just have one version.

What you can do is to have a setpath77.bat command which you only use in the command prompt where you wish to build g77. If you don't run setpath77 then it will revert to your old cygwin.

Say your g77 is installed in C:\f77\bin and the libraries (the .a files) are in C:\f77\lib. setpath77.bat will look something like this

path C:\F77\bin;%path%
set library_path=C:\F77\lib

You can use 2 cmd prompts: one with the old cygwin and one with the g77 you've built.

Cygwin is as bad as Java when it comes to versions.

Finally I uninstalled cygwin as I was going to use it only for g77, I deleted all cygwin1.dll's and all g77.exe's and installed force, which works perfectly with g77

Thanks agian for the tips
