Hi,
This is what i have tried so far...
I installed a software(e-cell, bioinformatics related) that uses gcc as the default compiler, on 15 node linux cluster. I want to change the compiler from gcc to mpiCC, to parallelize the software. The software has C++ core, and python bindings as front end. For this first i tried changing the python script which calls gcc to compile. But this gave out different kind of errors. So i went ahead forcing to use mpiCC compiler when configuring, rather than the default gcc. Different variations of commands i've used so far are,
$./configure CC=mpicc CXX=mpiCC
$./configure --with-CC=mpicc --with-CXX=mpiCC
for all these alternatives, configure does not give out any error, but when it comes to make, it fails.
$make CC=mpicc CXX=mpiCC
$make
For this i get errors like....
mpiCC -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../.. -I/usr/include -I/workx5/ecell3 -I../../libltdl -g -Wno-pmf-conversions -g -Wno-pmf-conversions -c libecs.cpp -DPIC -o .libs/libecs.o

The software is working fine with gcc, and as mpiCC is just a wrapper of gcc, it should not be a big problem to change the compiler. This is what i've done so far...and for the problem with pgCC part....
pgCC-Warning-Unknown switch: -Wno-pmf-conversions
Wno-pmf-conversions is realted to C++, and the description in man page is,
"Disable the diagnostic for converting a bound pointer to member function to a plain pointer"
is there is an mpi alternative for this? is there any other way of solving this problem?
Thanks,
Nithila.
