How to install the PythonWrapper on Raspberry PI after compiling the libCMSISDSP.a library?

[PhilWareFenTech]

Hi,

Trying to install CMSISDSP with pip install fails on my Raspberry PI 3, so thought I'd compile it myself.
I've run CMake and make and it generated the bin_dsp/libCMSISDSP.a library.

How do I create the python module I can then install to my python3 system?

Thanks,
Phil.

@PhilWareFenTech I hope at some point to find the time to deliver a binary version for Raspberry and that uses the Neon optimizations.

At the root (CMSIS-DSP folder where you can see the setup.py file), type:

pip wheel . --no-deps -w dist

You should now have a dist folder containing the package that you can install with a pip install path_to_package

Thanks for your quick help.

There seems to be a lot of things wrong though.
I added the numpy version check with #prama message;
PythonWrapper/cmsisdsp_pkg/src/cmsisdsp_module.h:41:9: note: ‘#pragma message: NPY_API_VERSION is 0x00000013’

So I'm using numpy-2.2

I've tried to pip install numpy-1.25, but it fails the same.
Interestingly it complains the version is still 0x13 - which is numpy v2.2, but my Pip List says it's 1.25, and I verified it with checking the python envirnoment site-packages.

It feels like I've broken something...

I've cleaned, re-created the PythonWrapper and made the lib.a file again, and run python install .

Although I've checked my numpy install version (1.25), and it checks in the setup.py script that it is 1.25, when the preprocessor runs on the cmsisdsp_module.h file, NPY_API_VERSION is still reporting 0x13 - which is v2.2

I have not rebuilt this wrapper for a long time and it looks like there is a new problem unrelated to NumPy. A commit has removed some functions from CMSIS-DSP that had been deprecated for a few years (like DCT4).

But the Python wrapper has not yet been updated and it looks like it still refers to those function. As consequence it cannot be built.

[christophe0606]

For NumPy "problem", I suggest you create a virtualenv. Install manually the v2.2 version. Build the package from this.

After, the resulting wheel should also work with older Numpy versions.
