Uploading `conda-forge` channel

[munechika-koyo]

Hi!

I am trying to add calcam to conda-forge channel following this instruction and posted the PR to conda-forge/staged-recipes/ repository: conda-forge/staged-recipes#24702

If you are welcome this addressing, could I have it reviewed by conda-forge maintainer or accomplish it?
I think there is room for who is included as a recipe's maintainer.

Thank you in advance.

I noticed that calcam with only python 3.11 are uploaded in the Anaconda calcam channel probably because of the timeout from #114?
Conda-forge registering should resolve this issue as well.
Additionally, the reviewer asked me why libstdcxx-ng is required here. Could someone please answer this?

Hi!

Really sorry I didn't reply to this for so long!

The reason for the libstdcxx-ng run_constrained requirement is because when I was testing the recipe (on Ubuntu), I found that with the version of libstdcxx-ng from the main channel, which is v11.2, VTK is broken! When I try to start any calcam GUI which uses VTK, I get a crash with error:

The read operation timed out
libGL error: MESA-LOADER: failed to open radeonsi: /usr/lib/dri/radeonsi_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: radeonsi
libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: swrast

Updating libstdcxx-ng to the version from conda-forge which is v13.2 fixes the problem. So the requirement on libstdcxx-ng is to force the update of this library at install time.

I just did a new release of Calcam to v2.13 - it also introduces a couple of new dependencies. I'm happy for you to update your recipe and reply to the reviewer with this info if you want, or I also prepared one at https://github.com/ssilburn/conda-forge-staged-recipes which I could do a pull request from - whichever you prefer!

Thank you for responding to my comment, and congratulations on the new release!
I have also updated my recipe and submitted a PR.

I kindly request that you take a look at the PR and leave a comment as it requires the maintainer's input.
Thank you in advance for your time and assistance
