scale build error => error: name followed by "::" must be a class or namespace name

[gokhan]

Hello,

I am trying to build SCALE 6.2 and getting the following error during make. I was able to compile it a few weeks ago. MPI version: 4.0.0 and 4.0.2 both result in the same error:

Thanks for your help in this,

Hello Gokhan,

What's different compared to a few weeks ago when you compiled successfully? Is this your first parallel build? 

Best,
