Re: pkg-config is not installed on the system

 

I have done this (again?). I have also checked .profile where I already had the line suggested by Ilmar. However, there are still several demos not working. And I still have the same error, e.g. for stokes/stabilized/python/demo.py (while stokes/taylor-hood/python/ demo.py works):

Make sure your PKG_CONFIG_PATH contains the path to where your FEniCS
pkgconfig files go. Running 'source dolfin.conf' in the DOLFIN folder
ought to set this for you.
