Dear David,

libsmumps_seq is the sequential Mumps library. May be you installed the 
parallel one (libsmumps). Please check.

Dear Getfem users, 

beside the interface problem, i noticed that there is another issue. When i 
compile the test case, for instance, i get the following error 

ld: library not found for -lsmumps_seq 

And since i am on Mac, i didn't find how to obtain the missing library (as 
recommended on the Getfem download page, i used brew to download mumps but 
that's it). Is there anyone who had a similar problem on Mac? 

Thank you in advance,
