Argh, the problem is that the issue appears on `plt.show()`, not before: ```python import matplotlib matplotlib.rcParams['text.usetex'] = True import matplotlib.pyplot as plt plt.title(r'\TeX\ ') plt.show() # ==> Exception ``` But...

If you refer to [CubicalComplex.cofaces_of_persistence_pairs documentation](https://gudhi.inria.fr/python/latest/cubical_complex_ref.html#gudhi.CubicalComplex.cofaces_of_persistence_pairs), it says: > The top-dimensional cells/cofaces of the positive and negative cells, together with the corresponding homological dimension, in two lists of numpy arrays...

For alpha complex, if points dimension is 3 and points are not on the same plane, the algorithm is using behind the scene is not the same as it will...

I reproduced the issue on a OSx virtual machine. I know it also requires opengl. I did `brew install glfw` but it doesn't help. [EDIT] I found a fix in...

`cmake -DPython_ADDITIONAL_VERSIONS=3 -CMAKE_BUILD_TYPE=Release ..` will fix the CGAL warning (should be better documented on our side - cf. #87 ). From what I see in your logs, Qt5 is well...

I installed libQGLViewer [this way](http://libqglviewer.com/installUnix.html): ```bash cd install/libQGLViewer-2.7.2/QGLViewer/ qmake -spec macx-g++ PREFIX=/usr/local make sudo make install ``` CMake did not manage to find QGLViewer that has been installed in `/usr/local/lib/QGLViewer.framework/`....

And now I am facing [this bug](https://bugreports.qt.io/browse/QTBUG-80990) that can be easily workarounded, but that I have to fix.

Compiling GudhUI (a Qt/C++ user interface for gudhi) is different from the Python module (the gudhi python module). It seems you confuse both. What I see from the cmake logs,...
