Errors while installing the library

[ioannaMitropoulou]

Hello, I follow the instructions in the README for the installation, but I get an extensive error when I try to use pip install -e . I paste the error here:

I noticed that the pybind11 is missing from the cmake paths and the ext folder. Does it have to be added manually?

Thanks, Ioanna

haven't worked on this in a while. will have a look. are you interested in specific functionality or just exploring?

[ioannaMitropoulou]

Firstly I am interested in the geodesic distances. Then I also want to use this project as a template to expose some more libigl functions which are not available in python yet and would be very useful to me.

I should also mention I am running the installation on Windows 10.

[tomvanmele]

the installation instructions are outdated. we have tried to release this package via conda-forge but the process was a bit slow and i gave up :). however that means you have to install using conda-build. it is not more or less complicated. just different. testing the procedure now on mac and windows and will update the instructions as soon as it works.

if you plan to wrap more of igl's functionality, perhaps you can just contribute to this repo?

the plan for compas_libigl is to remove all the cgal related stuff as this is now handled by compas_cgal and focus on the signature igl things, like the conformal maps and parametrisations...

[tomvanmele]

okay this was a bit more complicated than expected. i updated the repo and the instructions. tested the procedure on windows. everything should be fine with a good old pip install...

let me know if you have problems!

[ioannaMitropoulou]

Thanks now it works well! I installed the Python and build the Cmake for Visual Studio, and all looks good so far. Regarding the igl functions I want to wrap, I was interested in shape deformations, mesh cutting, and remeshing along isolines. I will fork this repository, and if I have something that could be useful for others, I will let you know.
