[Pw_forum] Another day another compilation problem

[H.S.Domingos]

Dear all,

I have compiled the pwscf code on a linux i686 cluster and strangely I do 
not get the MPI version when I run pw.x.
I have been unable to work out the problem. I assume that it is about 
make.sys and the parallel environment. Can I please ask your help on this?
You seem to have a knack for getting it right the first time.

Thank you very much in advance.

The make.sys after doctoring is :
