MEDCoupling installation Error

Install & build
1

Hi

I am trying to install medcoupling package on Ubuntu 20.04 LTS. The compilation was not successful. The following error message appeared,

configure: error: in `/home/yikun/App/medcoupling/MEDCOUPLING-9.8.0-MPI-UB20.04-SRC/BUILD/medfile':
configure: error: MPI CC compiler requested, but couldn't use it.
See `config.log' for more details

Compilation of MEDCOUPLING ................... ERROR : the following mandatory product(s) is(are) not installed: boost medfile doxygen

Compilation: KO (41/44)

I have strictly followed the readme instruction on the installation,
source,

source ./salomeTools/complete_sat.sh

prepare the installation

./sat prepare MEDCOUPLING-9.8.0-MPI

and then compile the code

./sat -t compile MEDCOUPLING-9.8.0-MPI

If checking the MPI version, I got the following by “mpirun --version”

mpirun (Open MPI) 4.0.3

My questions are:

  1. where can I find the config.log file.
  2. Is MPI a very necessary functionality to medcoupling? Should I switch it off, and how do I configure such?

Thank you for your helps in advance.

Eventually I will use this package with code_satune for more complex modelling work.

Hi,
from your message, one can read that several products compilation failed (boost, doxygen, etc.)
You can either share your LOGS folder which can give some additional information about what’s missing on your node.
If you’re looking for the sequential version, you can try to compile it as follows:

export CURRENT_DIRECTORY=$PWD
#  retrieve SAT
git clone https://git.salome-platform.org/gitpub/tools/sat.git SAT
git clone https://git.salome-platform.org/gitpub/tools/sat_salome.git SAT_SALOME
cd SAT
./sat init --add_project ../SAT_SALOME/salome.pyconf
cd $CURRENT_DIRECTORY
SAT/sat prepare MEDCOUPLING-9.8.0
# compile  MEDCOUPLING
SAT/sat compile MEDCOUPLING-9.8.0
# generate runtime environment setup script
SAT/sat environ MEDCOUPLING-9.8.0
# generate an archive which contains MEDCOUPLING binaries only
SAT/sat package MEDCOUPLING-9.8.0 -b

If compilation fails, you can then share MEDCOUPLING-9.8.0-UB20*/LOGS for further analysis. This directory contains the compilation log files.
HTH.
NB: Note that openmpi is embedded in the MPI version. system OpenMPI is not used.

Hi Thanks for your fast reply! Sorry about my late responses.

I found the root cause of the issue. This may be useful to other people.

It was the cmake. I was running the installation on the mounted folder which leads various errors of installation of the cmake. I have moved the whole thing to the local linux folder, the cmake can be installed then.
