Even with the new build system I still had to go through and eliminate the -g3 in petscvariables

but you missed copy/pasting the actual compile command. So incomplete info here..

I added -v in the local folder's makefile to produce verbose output.

Hm - we've seen these errors with -g3 but not with -g. Are you sure there is no '-g3' somewhere on the compile command?
With latest petsc-dev/buildsystem one should not see -g3 [set by configure]
Also - why is there 'cicc' in a petsc build?

Hi all,
Has anyone run into any problems with NVCC 4.1 or .42 on PETSc with arch=sm_20? I have having real issues with it. I keep getting this:

4.0 works fine, no issues. 4.0 version uses the older nvopencc, in 4.1 and 4.2 they use something called cicc, for target architecture sm_2x. Of course it does no mention cicc in the updated nvcc documentation at all.
Tried 4.2 with GCC 4.3 and 4.4 without any difference in behavior.
