openmesh installation fails on Windows 11 as a result of ssize_t unrecognised in MSVS 2022 #131

alastaira · 2023-07-06T07:29:59Z

I have an existing installation of Mightyscape v1.2 on another Windows 10 machine, which works great, so I thought I knew how to step through the installation process! However, on a new laptop, I've had quite a job stepping through the requirements, and I think I've identified the problem to an issue with latest versions of MS Visual Studio not supporting the "ssize_t" POSIX datatype used in openmesh:

Steps followed:

Cloned the Mightyscape GitHub repository
Installed latest version of Python (3.11)
Added Python interpreter to Inkscape preferences.xml
Installed latest cmake (3.27.0)
Installed MS VS Community Edition 2022 (v17.6.4), enabling support for building C++
Edited windows registry to enable long paths
Upgrade PIP
Run pip install --upgrade --no-cache-dir -r C:\Users\alast\Documents\GitHub\mightyscape-1.2\requirements.txt

Complete error message follows, but after ignoring warnings, the first relevant error appears to be:

C:\Users\alast\AppData\Local\Temp\pip-install-2txlq5nm\openmesh_e3bffb848b1447b1a9fb9f326e67ceab\src\Mesh.hh(362,7): error C2065: 'ssize_t': undeclared identifier (compiling source file C:\Users\alast\AppData\Local\Temp\pip-install-2txlq5nm\openmesh_e3bffb848b1447b1a9fb9f326e67ceab\src\Bindings.cc) [C:\Users\alast\AppData\Local\Temp\pip-install-2txlq5nm\openmesh_e3bffb848b1447b1a9fb9f326e67ceab\build-setuptools\temp.win-amd64-cpython-311\Release\openmesh.vcxproj]

A quick Google search suggests that this same issue appears to be described in other projects, as a result of newer versions of VS?:

numpy/numpy#21073
https://groups.google.com/g/snappy-compression/c/xzKxBNeAREc
https://forum.freecad.org/viewtopic.php?p=588239

Any suggestions as to how I can easily fix this to enable all MightyScape requirements to be compiled and installed without requiring fiddling about with my other settings?!

Thanks very much for all your work on this project :)

Hi,
basically this is an issue with openmesh library, which source is hosted at https://gitlab.vci.rwth-aachen.de:9000/OpenMesh/OpenMesh

You could try to create some issue there. I did not compile openmesh for myself a longer time so i cannot test it at the moment.

To fix your issue, can you try what happens when you install precompiled binaries for openmesh instead? i just found them right now. i did not know that they exist. maybe this will shorten the setup

there is also a another project for the python bindings: https://gitlab.vci.rwth-aachen.de:9000/OpenMesh/openmesh-python

Ok, I ran into similar install issues on win11.

I've used this plugin pack for years on Debian Linux (very fun for grbl), but as I stare into the void of modern Win11 I am reminded why I rarely use the OS.

Anyway, I managed to get a bit farther than the other user, but am getting a weird error insisting cmake isn't installed.

I am unfamiliar with the cmake package errors on Win11, so if anyone can drop in to close the ticket with a fix we would all be grateful.

Cheers,
J
