It was failing for me with:

File "/home/user/builds/python-ocp/src/OCP/pywrap/bindgen/", line 48, in read_symbols
sym = pd.read_csv(p,header=None,names=['name'],delim_whitespace=True,
TypeError: read_csv() got an unexpected keyword argument 'error_bad_lines'

in the Dumping symbols, then generating bindings... part of the building process just days after (eventually) successfully building it on other device. Same issue with the git version of this package.

A quick hack that fixed the issue for me was modifying PKGBUILD to include:

find ./ -type f -name "*.py" -exec sed -i 's/error_bad_lines=False/on_bad_lines = "skip"/g' {} +

In this part of the build:

build() {
cd OCP
local site_packages=$(python -c "import site; print(site.getsitepackages()[0])")
ln -s "${site_packages}"/clang15 clang
export PYTHONPATH="$(pwd):${PYTHONPATH}"

find ./ -type f -name "*.py" -exec sed -i 's/error_bad_lines=False/on_bad_lines = "skip"/g' {} +

msg2 "Dumping symbols, then generating bindings..."
PATH="/usr/lib/llvm15/bin/:${PATH}" LD_LIBRARY_PATH="/usr/lib/llvm15/lib:${LD_LIBRARY_PATH}" cmake -B new -S .

I did not delve deeper into how / why it works, I just applied the first fix given by looking up the error ( ). I hope someone finds it helpful, or confirms if it is a wider issue or just limited to my setup.

Hi greyltc, it works now! Thanks for fixing the issue ;)

Should be fixed now tapia. Turns out the official package upgrade of clang/llvm and friends from version 15->16 on 2023-08-29 broke the build. Took me almost forever to figure this out and implement a fix :(

Hi, this is not compiling for me. Is it working for anyone?

The vtk dep here is stuck at 9.1 for now. You'll have to downgrade/ignore vtk upgrades for this package to work. Once opencascade gets upgraded to 7.7 I'll be able to update this package to unlock it from vtk 9.1.

Looks like the recent vtk update in the main repos may have broken the dependency checks for this package. python-ocp-git seems unaffected.

It's not building anymore:

.cache/yay/python-ocp/src/OCP/OCP/BRepPrimAPI_pre.cpp:64:47: erreur: la valeur void n'a pas été ignorée comme elle aurait dû l'être
   64 |         Standard_Address OneAxis() override { PYBIND11_OVERLOAD_PURE(Standard_Address,BRepPrimAPI_MakeOneAxis,OneAxis,) };

please add the missing dependency or orphan the package and i'll do it. thanks!
