I'm attempting to build mrv2 as GPL (clone of main as of an hour ago), but I keep hitting a snag:

[200/265] Performing build step for 'Python'

I tried adding a system env variable PYTHON and setting it to C:\msys64\ucrt64\bin\python.exe, but that created a bunch of failed certificate handshake errors instead so I've removed it. I already added msys to my User PATH when installed (C:\msys64\ucrt64\bin). I also have python 3.13 installed (MS Store install), but it's not present in user or system PATH (nor is any other version of python for that matter, which is reflected in the log). Do I need to add Python to my user or system path?

Here's my complete log: compile.log

Okay, I found the issue. The find_python.bat script looks for python versions only up to 3.10 (it has not been updated) and it has the nuget approach completely broken. I had installed v3.10 myself in my machine and that's why it was working for me.

In any case, do:

git pull
./runme.sh --gpl

Give it a try as it works for me now.

I am not familiar with nuget. But in general to build python on Windows, you should download a version of python for Windows from the official web page not from nuget or from Msys' pacman.

You don't need it in your PATH I believe, as the installer will use py.exe and that will select the latest version of python.

Anyway, in any case, in an MSys window, check:

which python
which py

I should probably add to the build instructions for Windows that you may need some python version already installed.

Anyway, let me know if that helps.

Ok, checked those and got:

$ which python
/c/Program Files/mrv2-v1.2.8/bin/python

$ which py

So, it looks like it's pointing to my installed (non-GPL) version of MRV2's python install (which I checked to true during install, and added mrv to PATH).

I'll try uninstalling the current version of mrv2, clear that from my PATH and retry the which checks in MSYS

Ok, after uninstalling mrv2-1.2.8 and the Microsoft Store version of Python, I downloaded the standalone Python 3.13 installer directly, installed for all users and added it to PATH. After a restart, MSYS gives me these results:

$ which python
/c/Program Files/Python313/python

$ which py
/c/Windows/py

Much better. That'll teach me to use MS Store to manage dev environment tools! Trying to recompile mrv2 as GPL now. If I don't report back, that'll mean my issue is resolved. Thanks!

The problem seems to be with the nuget's python installer that does not exist.

Please download and install python (>3.9) from the official repository at:

https://www.python.org/downloads/

Then start the MSys2 terminal again. BTW, you don't need to add this downloaded python to the directory. If you want to use it, you would call py.exe instead of python.exe.

If that still does not work, to debug it, try:

cd BUILD-MSys-amd64/Release/deps/Python/src/Python

In PCbuild/, there's build.bat and find_python.bat.

Try adding some echo commands to print out the variables in both build.bat and find_python.bat and manually run:

PCbuild/build.bat

Okay, I found the issue. The find_python.bat script looks for python versions only up to 3.10 (it has not been updated) and it has the nuget approach completely broken. I had installed v3.10 myself in my machine and that's why it was working for me.

In any case, do:

git pull
./runme.sh --gpl

Give it a try as it works for me now.

I checked the intermediate file dir referenced above and USD/.../arch/Release is indeed not present. For now, I'm just going to disable building USD as I don't need it right now, but just thought you should know!

Try pulling main (or tag v1.2.9) and compile again. I fixed the USD build with a patch (Pixar inadvertently broke the compilation on Windows)
