[Coin-discuss] ClpCholesky

[Andreas Waechter]

Hi Paul,

I think the problem is that the makefiles are not set up to compile the 
WSMP interface code (nor the UFL code).  If you need it, I can fix that.

Instead of clogging the mailing list, we should probably communicate via 
the Clp Trac system.  Please submit a ticket there, and let me know which 
version of Clp you are using (trunk?).  Once you submitted the ticket, 
please send me a message.

Cheers

Andreas
