CyLP 0.92.3 Windows wheels?

[Owen-OptiGrid]

I'm trying to install cylp 0.92.3 on Windows 11 with Python 3.12.6 - I noted there's no Windows wheels created for this version it appears.

I tried letting pip build from source but I keep getting msbuild errors like this:

I tried building against each of the CBC 2.10.12 windows binary releases here to no avail.

I installed the Visual Studio C++ Build Tools as shown:

Sorry about this, I forgot to build wheels for Windows last release. I'll try to do that today. Everything has to be built with the correct run-time library and I guess you are getting some mismatches. It's a pain.

Thanks for looking into building the wheels! I saw that was difficult to setup actions for. Get Outlook for Android<https://aka.ms/AAb9ysg>

OK, the Windows wheels are there now. I'm not sure how you did your Windows build but if you used coinbrew, then you need --enable-msvc=MD to get the correct run-time. It looks like the Actions builds use the default, which is MT, although the files are named *-md. I thought we had this sorted, but perhaps not.

[tkralphs]

@jhmgoossens I think I remember that we discussed the --enable-msvc flag when you set up the latest workflows for Github Actions. We evidently decided to only build with the the default \MT, but somehow, we are still naming the Windows archives with a -md suffix. For building C extensions with Python, we need \MD.

I opened two PRs (one for master and one for stable/2.10) that correct the problem with the suffix and add \MD builds. With these builds, it is now possible to pip install CyLP from source by downloading Cbc-w64-msvc17-MD.zip.

Can you take a look and see if you agree? I guess that we only need these additional builds for Cbc and not all the other projects in the stack. Obviously, this violates my principle of having the same workflow files everywhere, but I guess we can realign them next time we do an overhaul.

Also, @Owen-OptiGrid , could you test whether these binaries work for you?

[Owen-OptiGrid]

Sorry I missed your message - I've moved onto other tasks not requiring CyLP for a while but I'll see if I can try the new build files sometime soonish. Thanks for putting up the new builds!
