Grass conda on Windows

ecodiv · May 13, 2026, 12:10pm

I haven’t tried it myself yet, but a student of mine is looking into installing GRASS via Conda on his Windows machine. However, information seems to be a bit unclear about what is possible.

According to this LinkedIn post, https://www.linkedin.com/posts/huidaecho_grass-activity-7455626363102806017-oRiY/ , is grass available on Windows via Conda, with additional information on https://grass-conda.isnew.info/.
On conda it says that grass package is available on conda-forge for Linux (64-bit) and macOS (Intel and Apple Silicon).
And on Conda Forge, conda install conda-forge::grass, it only seems available for 8.4.2.

He hopefully will figure out how to get things installed, but perhaps it is in any case good to have the full picture on conda ?

Cheers,

Paulo

The conda forge doesn’t seem updated since beginning of January. Also see grass v8.5.0 by regro-cf-autotick-bot · Pull Request #12 · conda-forge/grass-feedstock · GitHub

I don’t know who updates the feedstocks for conda forge

Hi Paulo,

Edouard is right. Conda-forge cross-compiles for macOS arm64 on Azure pipelines, and I still need to figure out how to do this using CMake. My personal conda channel https://grass-conda.isnew.info/ provides 8.4.2 (no Windows), 8.5.0, and dev versions. This is possible because GitHub Actions CI does native compilation. Maybe, I need to publish native packages on conda-forge first?

Thanks,
Huidae

Thanks, Huidae and Edouard,

Huidae, I shared your page with my student, and he is going to try to get things installed. I will leave a message here about how things work out when he gets back to me.

Cheers,

Paulo

For now, I’ll skip osx-arm64 cross-compilation for the official conda-forge release and merge my PR.

Edouard, I’m updating the feedstock for conda-forge.

Best,
Huidae
