You have posted the almost exactly the same thing 4-5 times now, and I
have already replied with the solution. I'm not sure why my words are
not conveying the basic knowledge required for you to continue on with
your project (please go re-read my posts on the web archives), but I'll
try one last time:
1. your software requires the g++ compiler
2. your mpiCC is *not* using g++ (it is using pgCC)
3. hence, your software cannot be compiled with mpiCC
4. to fix this, you need to change mpiCC to use g++
5. note that it's not 100% clear that you're using LAM/MPI (you did not
answer my questions about this). *IF* you are using LAM/MPI:
- I strongly recommend talking to your system administrator about
performing the rest of these steps for you
- LAM needs to be recompiled with g++ instead of pgCC
- for example, in the LAM source tree:
./configure CC=gcc CXX=g++ FC=g77 ...rest of your options...
- this will automatically make mpiCC use g++ instead of pgCC
- then you can compile your software with mpiCC (because it will now
use g++, which your software requires)
If you have questions about specific steps above, please feel free to
ask. Good luck.
