Build and Install Basic Test Python Type Support - "zsh: command not found: itl2py"

[Danny875]

Hello,

After typing the following command in the terminal: "itl2py -o basic_output basic_idl basic.itl", I'm getting the following error:

dannyguest@Dannys-MacBook-Pro build % itl2py -o basic_output basic_idl basic.itl
zsh: command not found: itl2py

Is there any way to solve it?

Thank you in advance!

itl2py should be installed with the pyopendds package, so what does pip show pyopendds say?

[Danny875]

I get the following:
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
WARNING: Package(s) not found: pyopendds

Is there any way to install this package with brew?

[iguessthislldo]

Okay, that's the pip for Python 2. Is Python 3 installed? You'll need it to use PyOpenDDS. If you do have it try pip3 install pyopendds.

Is there any way to install this package with brew?

For PyOpenDDS? No, it's only available from source (pip install .) or through PyPi (pip install pyopendds).

By executing "pip -V", I'm getting the following output:
pip 21.2.4 from /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/pip (python 3.10)"

After executing "pip3 install pyopendds", I'm getting the following error:

Thank you in advance!

This is something completely new to me, so it would require more investigation. If I'd have to guess from the log through, it might be a change in how CPython 3.10 builds native extensions that my CMake code isn't expecting. This might be that the current directory that was the source before is now a temporary copy or something like that.

Okay I didn't get the same exact error, but with Python 3.10 on Linux after installing the wheel package so that it would build it as a wheel I got this:

  ERROR: Failed building wheel for pyopendds

Before this though pip happened to be warning about:

DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.

I tried passing --use-feature=in-tree-build and that worked. Getting past that though, there seemed to be an issue with the C API that stopped the native extension from compiling with Python 3.10. I pushed a fix for that in on the master though, so you should get those changes first and then try running pip3 install . --use-feature=in-tree-build in the PyOpenDDS directory.

Dear Fred,

Thank you for taking the time to analyze this issue and provide me with an answer. I have downloaded the latest version from GitHub and tested it on my Mac and also on my Raspberry Pi. I also installed the "wheel" package on both machines.

On the Mac, the "pyopendds" was successfully installed.

On the RaspberryPi, it seems that something is not right yet.

This is the output that I get from the Raspberry Pi, after executing "pip3 install . --use-feature=in-tree-build":
