Building CalculiX with PaStiX on FreeBSD without CUDA

21

Thanks for sharing your findings!
I was able to build CalculiX with PaStiX (without CUDA) on macOS with minor modifications.
In case someone ends up here with the same intentions:

  • Use Kabbone’s version of PaStiX4CalculiX: GitHub - Kabbone/PaStiX4CalculiX
  • Install scotch, hwloc, openblas, lapack using hombrew
  • Make sure you have a python2 installation somewhere (I got mine using pyenv)
#!/bin/bash
if ! [[ -d build ]]; then
    mkdir build
fi
cd build

INSTALLPATH="./"
SCOTCHDIR="/opt/homebrew/Cellar/scotch/7.0.7"
HWLOCDIR="/opt/homebrew/Cellar/hwloc/2.12.0"
BLASDIR="/opt/homebrew/Cellar/openblas/0.3.29"
LAPACKDIR="/opt/homebrew/Cellar/lapack/3.12.1"

cmake \
	-DCMAKE_INSTALL_PREFIX=${INSTALLPATH} \
	-DCMAKE_BUILD_TYPE=Release \
	-DPASTIX_WITH_PARSEC=OFF \
	-DSCOTCH_DIR=${SCOTCHDIR} \
	-DHWLOC_DIR=${HWLOCDIR} \
	-DLAPACK_DIR=${LAPACKDIR} \
	-DBLAS_DIR=${BLASDIR} \
	-DPASTIX_ORDERING_SCOTCH=ON \
	-DCMAKE_C_COMPILER=gcc-14 \
	-DCMAKE_CXX_COMPILER=g++-14 \
	-DCMAKE_Fortran_COMPILER=gfortran-14 \
	-DCMAKE_C_FLAGS="-framework accelerate -fopenmp -Wno-error=implicit-function-declaration" \
	-DPASTIX_INT64=OFF \
	-DPYTHON_EXECUTABLE=python2.7 \
    ..

make -j4
make install

I additionally had to change the version number to 3.5 in some cmake files, since I was using a more recent cmake version:

cmake_minimum_required (VERSION 3.5)

(cmake will complain and show you the affected files)

And finally, here is my CalculiX Makefile:
