[Trilinos-Users] Trouble building Trilinos with CLAPACK

[Christian Staudt]

Thank you, Mike, Kermit, Brent and Doug, for the hints. 

First, I rebuilt CLAPACK using cmake instead of the makefile supplied. With that, the Trilinos build completes without errors.

Now that the LLVM GCC does not seem to have caused the problem, would you still advise against using it?

(I am now trying to figure out how to build an application in Eclipse (with CDT) against Trilinos.)
