hi there @aaron-pratt

Sorry for the confusion. As stated in the change-log (look for a change log file in the repo), I changed the compilation method from MSVC (MS Build Tools) to MingW. There is a document compilation on windows on the top of the repo and it explains how to do it (it's easier, but you would depend on conda instead of MSVC).

Why are you building from source in first place? If you install with pip or conda you will get immediately a pre-compiled wheel so that you don't need to compile.

The reason why I changed the compilation method is because the C library librdata is not compatible with MSVC. I was manually patching the copy I have here of librdata to work with MSVC; however in this last version a new feature has been introduced (handling bzip compression), where the patch was no longer working, so my way to move forward has been to change to MingW that is fully compatible with librdata. In addition doing the manual patching everytime I need to update librdata is error prone and tiring, while now I can simple copy and paste. In some long future I hope that they make librdata officially compatible with MSVC.

If you would insist on keep compiling with MSVC (why?), there is a document librdata jamovi differences that explain in which lines of librdata write what to make it to work with MSVC. You can take a fork of pyreadr, apply that and also take out the bzip compression from setup.py and you would get back to normal. I can help there but I wouldn't do it unless you have a very good reason to do so.

Hope it helps.

Hi @ofajardo,

If you look to the top of the output above, this is using pip... Maybe the pre-compiled wheel for Windows has the issue?

Looking through the errors it looks to be driven from a whole bunch of syntax issues that the MSVC is not liking at all...

Appreciate all the help btw!

ahhhh, the wheels for python on windows are not in PyPi !!! (actually only the one for python 3.8).

Sorry for the confusion before. Let me fix the wheels, upload to pypi and then all should be fine.

from pyreadr.

OK ready. Can you please try again?

Since you have already a cached wrong version (the source distribution) maybe use --no-cache option with pip to be sure it gets the correct wheel.

You don't need MS Build Tools at all, just do it in a normal (or anaconda) command line prompt.

Perfect! All working again now :)

Thanks for the speedy response.
