I cannot reproduce this error.
Try starting over by first deleting the 'build' folder then using the command "python setup.py install --user --force".

@dkeeney Thank You.

Issue continue to persist.

Hmmm,well I cloned a fresh copy of htm.core and did a full build on windows using Visual Studio 2022 and Python 3.11. Everything worked.
The only thing I can think of that seems to be different is that I am using a virtual environment for python rather than running from Powershell. I am using virtualenv. I do not know if that is what makes the difference but it is the only thing I can see that is different from my setup.

Thank you @dkeeney tried again with virtual env, with complete new download, and build. But error persist.

Though unable to understand where is the issue stemming from, could you please give some pointers.

I think this time, your 'build' folder at "C:\Users\aryabhatta\Documents\Programs\htm.core\htm.core-master\build" already existed so it did not actually do a build.

The compile error issue stems from not having the C++ build environment in place when it compiles the placeholder object needed to package the bindings for Python so it did not know where to find stdio.h. This normally an indication that the build system is confused.

When you run a build from scratch, the CMake build system will download and build each of the prerequisites. When that is finished, it caches everything in the build folder and then proceeds to compile the htm.core library itself, then the unit tests, then packages the Python bindings. If the build aborts for some reason, it often leaves the CMake cache in a strange state such that the next time you run the build, it just does not do what you expect. So that is why you need to delete the 'build' folder after a failed build.

If that does not fix it...there must be something else that is different between our environments.

• Maybe your Global site-packages folder already has a (maybe corrupted or partial) entry for htm.core. ' Python -m site'
• Check your CMake install. must be at least version 3.7 but it is best to install the latest. I am using 3.25
• My python comes from https://www.python.org/downloads/ Python 3.11.1
• I am using Windows Visual Studio 2022 on a PC
• I am using virtual_env
