CMake Pardiso
The project demonstrates how to integrate pardiso into your CMake project.
Request a license key here.
Option 1: Install the pardiso library with cmake. Provide your license
key to cmake and specify the location where the pardiso
library will be installed via the cmake variable PARDISO_LIBRARY_DIR.
The directory PARDISO_LIBRARY_DIR will be created if it does not
exist yet:
cmake .. -DPARDISO_LIC_KEY=3499655142F33F994CF1792699F41534A832A6931DE83F438B0DUMMY -DPARDISO_LIBRARY_DIR=$HOME/code/libraries/pardiso
On old linux systems (e.g., CentOS Linux release 7.7.1908) try adding the option
-DPARDISO_GCC720=ON to download a pardiso library that links against glibc, v2.27.
Option 2: The pardiso library was previously installed to the
directory PARDISO_LIBRARY_DIR (either manually or with Option 1).
A pardiso.lic file containing the license
will not be created, and you do not provide a key:
cmake .. -DPARDISO_LIBRARY_DIR=$HOME/code/libraries/pardiso
PARDISO_LIBRARY_DIR must be an absolute path.
Here is a full list of commands:
module load gcc/7 intel cmake
mkdir -p buid && cd build
cmake .. -DPARDISO_LIC_KEY=3499655142F33F994CF1792699F41534A832A6931DE83F438B0DUMMY -DPARDISO_LIBRARY_DIR="$HOME/code/libraries/pardiso"
