[Trilinos-Users] [EXTERNAL] question about using ParMETIS with Trilinos

[Devine, Karen D]

Alicia:  Have you resolved this problem?  I know the link line needs to
list libmetis.a AFTER libparmetis.a.  It is not clear from your email what
order is used by TRIBITS.  Try running CMAKE with
-D CMAKE_VERBOSE_MAKEFILE:BOOL=ON
Then check the link line for the unit test with the failing build.  If
libmetis.a is before libparmetis.a, there is a bug in TRIBITS that needs
to be fixed; we can report it to the appropriate person.
