Greetings,
I have been struggling to get the Trilinos solver package built using
Cmake, but have been unsuccessful so far. I have been working this for
several days and need help. I’m attaching a recent request to the
Trilinos mailing list. Would you have any guidance for me? Thank you..
Sincerely,
Roy Hogan
Hi Roy,
from you logs, I see that
mpiexec is found
mpifort is found
it is not clear if mpicc is not found or not recognized.
On my system
$ mpicc --version
gcc (GCC) 4.5.3
My suggestion:
-) check that openmpi is correctly installed
$ cygcheck -c openmpi libopenmpi-devel
Cygwin Package Information
Package Version Status
libopenmpi-devel 1.7.1-2 OK
openmpi 1.7.1-2 OK
-) check that mpicc is working, see attached test case.
$ mpicc hello_c.c -o hello_c
$ mpirun -n 4 ./hello_c.exe
Hello, world, I am 1 of 4
Hello, world, I am 2 of 4
Hello, world, I am 3 of 4
Hello, world, I am 0 of 4
Regards
Marco
