unknown switch and unknown suffic

Accelerated Computing HPC Compilers Legacy PGI Compilers

Dear all,

I have an issue with pgf90

I tried to compile but it seems like there is no switch definition available.

pgf90-Error-Unknown switch: -c
pgf90-Error-Unknown switch: -O3
pgf90-Error-file with unknown suffic ignored: cfg_module.F

As far as I know, -c and -O3 should be a very common switch and most likely to be define in .pgf90rc or pgftnrc

But I could not find them in any of those files.

And for suffix, .F, it is very strage to me that compiler returned it as unknown suffix.

Anyone have any idea on this, please help.

Hi deutschf,

Anyone have any idea on this, please help.

This error typically means that you’re trying to run the compilers without first installing them or your installation failed for some reason. Can you go back and try reinstalling them to see if any errors occur?

Best Regards,
Mat
