Manual build process as of March 4th 2025

I went through the process of building this by hand and took some notes; figured I'd put them here in case anyone else needs them.

How to Build PyEMS From Source: RHEL 9.4 x86_64 as of March 4th, 2025

Start Process:

mkdir ~/openems
cd !$
git clone --depth=10 --recurse-submodules --shallow-submodules https://github.com/thliebig/openEMS-Project
cd openEMS-Project
mkdir build
sudo dnf install -y python3-devel
python3 -m venv my_ems_env
source !$/bin/activate
pip install --upgrade pip
pip install cython h5py numpy scipy pytest matplotlib

Get VTK:

I think VTK should go in ~/openems/openEMS-Project/VTK/ but I did it in ~/openems/openEMS-Project/build/VTK/

git clone --depth=10 --recurse-submodules --shallow-submodules https://github.com/Kitware/VTK
cd VTK
mkdir build
cd !$
cmake .. -DVTK_MODULE_ENABLE_VTK_GuiSupportQt=YES -DVTK_MODULE_ENABLE_VTK_ViewsQt=YES 
make -j32
sudo make install

Fix broken files:

Comment out two lines in three files:

1. QCXSCAD/CMakeLists.txt
2. openEMS/CMakeLists.txt
3. CSXCAD/CMakeLists.txt

  set(VERSION ${GITREV})
  #string(STRIP ${VERSION} VERSION)
  #message(STATUS "Found Git repository, ${PROJECT_NAME} version tag: ${VERSION}")
ENDIF()

Build /hyp2mat:

cd hyp2mat
sudo dnf install -y libtool bison flex gengetopt help2man groff paraview libharu-devel tinyxml-devel
sh ./bootstrap.sh
./configure
make
sudo make install

Run the Installer:

module load mpi/openmpi-x86_64
cd ~/openems/openEMS-Project/
./update_openEMS.sh ~/openems/openEMS-Project/build --with-hyp2mat --with-CTB --python

Build AppCSXCAD:

cd ~/openems/openEMS-Project/AppCSXCAD/
mkdir build
cd build
cmake .. -DCSXCAD_ROOT_DIR=~/openems/openEMS-Project/build -DQCSXCAD_ROOT_DIR=~/openems/openEMS-Project/build 
make -j8
sudo make install

Install Python Modules for CSXCAD:

pushd ~/openems/openEMS-Project/CSXCAD/python
python setup.py build_ext -I ~/openems/openEMS-Project/build/include -L ~/openems/openEMS-Project/build/lib -R ~/openems/openEMS-Project/build/lib --user
python setup.py install

Install Python Modules for OpenEMS:

pushd ~/openems/openEMS-Project/openEMS/python
python setup.py build_ext -I ~/openems/openEMS-Project/build/include -L ~/openems/openEMS-Project/build/lib -R ~/openems/openEMS-Project/build/lib --user
python setup.py install

Export build/bin to the path:

emacs ~/.bashrc
export PATH=$PATH:~/openems/openEMS-Project/build/bin

Install pyems:

cd ~/openems
git clone --depth=10 https://github.com/matthuszagh/pyems
cd pyems
python setup.py install

Run all tests:

source ~/.bashrc
cd ~/openems/pyems/
python tests/test_calc.py
python tests/test_coordinate.py
python tests/test_examples.py
python tests/test_structure.py

Run the horn example:

cd ~/openems/pyems/examples
python horn_antenna.py
