[Trilinos-Users] [EXTERNAL] NOX Undefined Reference linking issues with gcc 4.1.2

[Roger Pawlowski]

Hi Sean,

NOX is tested nightly on multiple machines against the gnu 4.1.2 
compilers.  All tests are compiling and passing.  The nightly test 
results can be found at the following webpage (I'm pretty sure the 
Trilinos cdash test results page is open to the public but someone on 
the framework team can correct me):

http://testing.sandia.gov/cdash/index.php?project=Trilinos&display=project

So, I'm not sure what the problem is.  You would have to send the actual 
output from the configure.  Do you have multiple versions of gcc on the 
same machine?  Maybe cmake is pulling in incompatible versions of the 
headers/libraries meant for the other gnu compiler version?

Roger
