Hi,
I'm getting a configure error while trying to build charm++ (so that I
can eventually build namd). The error is given in the forwarded email
below I had originally sent to the charm++ developers (no response yet).
In addition to what I have already tried below, I also tried adding
--basedir=/path/to/mpich2 in the charm++ build line but that didn't help.
Thanks,
Sabuj Pattanayek

Hi,
I also tried making a link from mpiCC to mpicxx in the bin path for the
mpich2 compilers but that didn't seem to help either. The script still
returns the same error. Looking at the configure file it seems that a
"Hello world" program is compiled using the compiler in question. I was
able to compile this program using mpiCC (linked to mpicxx). Perhaps
mpicxx doesn't like some of the flags in the test_cxx() function in the
configure script?
Thanks,

Hi,
I am trying to build charm++-5.9 using the following command:
./build charm++ mpi-linux smp -O2
everything is fine until this in the build script:
checking machine name... mpi-linux-smp
set C++ compiler as: mpiCC -D_REENTRANT
checking "whether C++ compiler works"... "no"
Cannot compile C++ programs with mpiCC -D_REENTRANT
(check your charm++ version)
make[1]: *** [conv-autoconfig.h] Error 1
make[1]: Leaving directory `/sb/apps/charm++-5.9/src/mpi-linux-smp/tmp'
make: *** [headers] Error 2
the following compilers are in my path:
49 trigger:/sb/apps/charm++-5.9% which mpicc
/sb/apps/mpich2-1.0.3/Linux2/i686/bin/mpicc
50 trigger:/sb/apps/charm++-5.9% which mpicxx
/sb/apps/mpich2-1.0.3/Linux2/i686/bin/mpicxx
Why is it looking for "mpiCC" as the MPI C++ compiler? Shouldn't it have
found mpicxx instead? For example if I build net-linux it properly finds
g++ as the C++ compiler and begins to compile. Can I set some
environment variables (e.g. MPICH_CXX or MPICH_CC) so that the compilers
are properly found?
Thanks,
