Hi
I get a compiler error when compiling cosmomc

mpif90 -mkl -openmp -O3 -xHost -no-prec-div -fpp -DMPI -I../camb -DNOWMAP -c calclike.f90
mpif90 -mkl -openmp -O3 -xHost -no-prec-div -fpp -DMPI -I../camb -DNOWMAP -c EstCovmat.f90

ld: library not found for -lmpi
make: *** [cosmomc] Error 1

it seems that this is not a problem with cosmomc, since the mpif90 compiler does not seem to find -lmpi in general

bash-3.2$ mpif90 -lmpi
ld: library not found for -lmpi

so this is more an openMPI question than a cosmomc question...
I compiled the openmpi package with the following configure command

./configure FC=ifort MPIFC=mpif90 --prefix=/usr/local/openmpi 2>&1 | tee c.txt

and the installation works without any problems

I added the following paths to my .bashrc file

PATH=/usr/local/openmpi/bin:$PATH ; export PATH
LD_LIBRARY_PATH=/usr/local/openmpi/lib:$LD_LIBRARY_PATH ; export LD_LIBRARY_PATH
DYLD_LIBRARY_PATH=$LD_LIBRARY_PATH ; export DYLD_LIBRARY_PATH

I have no idea why it can't find -lmpi
any suggestions are highly appreciated

I am working on Mac OS 10.8.2

thanks

I switched from mpich to openmpi and the problem went away...
