Hi Panu, hi everybody.

Yes, i know, I used "case" just to better express my idea,
but i didn't knew about %define within conditionals.

Didn't knew about %include , this did the trick.

For the record, here's how i did:


Contents of
%if "%{compiler_name}"  == "intel"
%{!?compiler_version:   %global compiler_version %intel_compiler_version}


%if "%{compiler_name}"  == "pgi"
%{!?compiler_version:   %global compiler_version %pgi_compiler_version}



%{!?compiler_name:      %global compiler_name gnu}
%{!?compiler_version:   %global compiler_version %gnu_compiler_version}

The problem must have been me, ;)
and as i fixed it with %include, i'm not going further with lua.

Thank you very much for your help!
