Install Error on Windows

[mengqi-z]

I encountered the following error when installing gcamwrapper on Windows with pip install .. It seems Windows does not support os.uname.

Processing c:\workspace\github\gcamwrapper
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

Hi @mengqi-z, can you successfully install gcamwarpper-python in windows for gcam7? I got some errors related to tbb. Did you encounter similar issues as below:

Hi @daleihao, Yes, I installed gcamwrapper for GCAM7 on Windows successfully after solving several different issues. I can't remember if I ran into the exactly same error you posted.

Hi @mengqi-z , happy to know you installed it successfully. I want to ask whether you use visual studio to compile it and which tbb version do you use for the installation? When you compiled GCAM7, did you disable GCAM Parallel by setting CAM_PARALLEL_ENABLED=0 following https://jgcri.github.io/gcam-doc/gcam-build.html? Thanks a lot!

[mengqi-z]

Hi @daleihao, I used visual studio to compile it. I believe I used oneapi-tbb-2021.2.0-win.zip. But to be honest, I am not 100% sure because I already deleted the downloaded zip file, and I cannot find the exact version info from my current tbb library.

I didn't disable GCAM Parallel by setting CAM_PARALLEL_ENABLED=0.

Got it. Thanks! @mengqi-z Do you have some notes for debugging the issues when installing it in Windows?

@daleihao I have the same problem and after changing several tbb versions it is still not solved . May I ask if you have solved this problem?

@mengqi-z Would it be convenient for you to send up a package of your current tbb files? so that we can troubleshoot if it's a problem with the tbb version.
