complex.h fail

[L-Vignali]

Hi everyone, I am getting this mistake in windows visual studio and python 3.10.4. The same mistake happens when manually trying to install (i.e, C:\Users\lvignali\Desktop\toolboxes\pycatch22-0.4.5>python setup.py build).

Hi @L-Vignali, This build error seems to indicate that the <complex.h> header isn't available or can't be found in your Visual Studio installation. I haven't been able to reproduce this error locally. Can you manually verify whether the complex.h header exists? It should be under the directory C:\Program Files (x86)\Windows Kits\{version number}\Include\{version number}\ucrt.

[L-Vignali]

Hi Joshua, thanks for the quick reply. yes, the file is there: C:\Program Files (x86)\Windows Kits\10\Include\10.0.22621.0\ucrt\complex.h Type: C Header Source File

Have you tried updating setuptools using pip install setuptools --upgrade before building and installing pycatch22?

[L-Vignali]

Yes, done that…

[jmoo2880]

It seems to building without errors in our Windows test environment (running python 3.10). Has this issue appeared only after updating to the latest release of pycatch22 (v0.4.5)? If you were previously using an older version (e.g., v0.4.4), did the installation succeed without any errors?

[L-Vignali]

Unfortunately it was the first installation. Also older version fail to compile. Is it possible is something related to permissions? I made sure I have full permissions for complex.h but if it happens somewhere before it is difficult for me to tell.

@L-Vignali I've pulled down latest and built a fresh wheel distribution in a clean Windows environment and uploaded it to the PyPI index. Can you give this a try and let me know how it goes? If you run pip install pycatch22 it should now pull the pre-built Windows distribution and install this instead.

Problem solved! Thank you so much Joshua!
