It's becoming clearer my ignorance of how c++ (specific to getfem++ and in
general) is to be rendered to run. It seems I should run 'make laplacian'
in /tests. Then when excuting ./laplacian it begs for parameters. So then
I noticed what appears to be a perl file (laplacian.pl) that would generate
such parameter schemes, so I run 'perl -W laplacian.pl' and it seems that
the $ENV{srcdir} is undefined and so it spits errors.
Any help for a lowly c++ newb?
Thanks,
Andy
