You need http://eigen.tuxfamily.org/index.php?title=Main_Page.
On Debian/Ubuntu and derivates, that's as easy as
sudo apt install libeigen3-dev
from pygalmesh.

Sorry I should have said I'm on a windows machine
from pygalmesh.

I changed the setup.py line "os.environ.get("EIGEN_INCLUDE_DIR", "\Eigen3")" so I get past that now.
I'm now getting "src/generate.cpp(5): fatal error C1083: Cannot open include file: 'CGAL/Exact_predicates_inexact_constructions_kernel.h': No such file or directory"
As far as I know I have the latest CGAL installed

These kind of linking errors are nearly impossible to debug without machine access. You'll have to dig around yourself I'm afraid.

Hi,
I've got a little further down the process trying to install pygalmesh on a Windows machine.
I've done the following:
- install eigen and cgal using conda install -c conda-forge eigen cgal
- added an environment variable 'EIGEN_INCLUDE_DIR' pointing to 'C:\Anaconda3\envs\py37\Library\include\eigen3'
Then doing pip install pygalmesh I'm now stuck on a compile error, which is:
C:\Anaconda3\envs\py37\Library\include\CGAL/Mesh_criteria_3.h(116): error C2664: 'CGAL::Mesh_cell_criteria_3<Tr,CGAL::Mesh_3::Cell_criteria_visitor_with_features<Tr>>::Mesh_cell_criteria_3(const CGAL::Mesh_cell_criteria_3<Tr,CGAL::Mesh_3::Cell_criteria_visitor_with_features<Tr>> &)'ÿ: impossible de convertir l'argument 2 de 'Arg' en 'const double &'
with
[
Tr=pygalmesh::Tr
]
and
[
Arg=const pygalmesh::generate_with_sizing_field::<lambda_db8e64dde8d1efacb3178dd659100057>
]
C:\Anaconda3\envs\py37\Library\include\CGAL/Mesh_criteria_3.h(121): note: Raisonÿ: impossible de convertir de 'Arg' en 'const double'
with
[

]
@nschloe Would you be so kind and translate the meaning of that error message for me?
Thank you

Looks like an outdated CGAL version.

Thanks for your quick reply. Indeed, the CGAL version on conda-forge right now is 4.14 (and they're not quite ready to move to CGAL5, see conda-forge/cgal-feedstock#54). So using conda-forge will likely not work until it provides the latest CGAL version... :(

@flothesof CGAL seems to be updated on conda-forge now. Any interest in writing a recipe for pygalmesh? Would certainly help a number of people.

Thanks for the suggestion. I've just tried the following on my Mac (not Windows) and it installed pygalmesh successfully:
conda install -c conda-forge eigen cgal
export EIGEN_INCLUDE_DIR=/Users/kappamaki/opt/miniconda3/envs/py37/include/eigen3
git clone https://github.com/nschloe/pygalmesh.git
cd pygalmesh
pip intall -e .
When I run pytest after that, I get:
============================================================================= short test summary info =============================================================================
FAILED test/test_inr.py::test_inr - RuntimeError: Caught an unknown exception!
FAILED test/test_remesh_surface.py::test_inr - meshio._exceptions.ReadError
FAILED test/test_volume_from_surface.py::test_volume_from_surface - File "<string>", line None
========================================================================== 3 failed, 26 passed in 26.44s ==========================================================================
This may or may not work on Windows, but it seems a good basis for trying to make a recipe on conda-forge. I'll give it a shot (I've never done this before).

I am on a windows computer. I followed your directions, @flothesof , and got past the Eigen\Dense issue. Now I am hung up on a new one. It seems connected to either my C++ compiler or to CGAL, but I thought CGAL was installed via conda-forge so I don't really know what to do. Any ideas?

@montallban This is a different issue that OP's. Looks like you don't have recent enough version of CGAL installed. Please open a new issue if you need more instructions. https://www.urbandictionary.com/define.php?term=Thread%20Hijacking

Let me point everyone towards https://anaconda.org/conda-forge/pygalmesh/. This should make installation on Windows a lot easier.
