Failed to build sysrepo libyang
ERROR: Could not build wheels for sysrepo, libyang which use PEP 517 and cannot be installed directly

I get a similar error from running pip install libyang.

Status

I have tried:

• pip install --upgrade pip setuptools wheel
• sudo apt-get install python3-dev
• sudo apt-get install python3.9-dev
• sudo apt-get install gcc python3-cffi

libyang is installed from source, and sysrepo already works fine on its own without the python bindings.

System Information

pip --version: pip 21.2.4 from /home/kkovacs/.local/lib/python3.9/site-packages/pip (python 3.9)
python --version: Python 3.9.5
OS: Ubuntu 20.04.3 LTS on WSL2 on Windows 10

Hi @nullromo

What versions of sysrepo and libyang do you have installed?

You stripped the most important parts of the errors :)

... hundreds of lines of GCC errors from sysrepo ...
... thousands of lines of GCC errors from libyang ...

That would allow to identify what went wrong.

I have commit 6f74fd18e5ace7d8f1ae6c1c1c2b7442dc263b22 of libyang and commit a6d470363a5438c0c817f4f13729caa310f5fbce of sysrepo, which are the latest versions on the master branches of those repos as of a few days ago.

I have added the full error output here

[rjarry]

It looks like you have recent (2.x) versions of the headers installed:

build/temp.linux-x86_64-3.9/_libyang.c:577:2: error: #error "This version of libyang bindings only works with libyang 1.x"
    577 | #error "This version of libyang bindings only works with libyang 1.x"
        |  ^~~~~

To compile the python bindings, you need libyang 1.x and sysrepo 1.x installed along with their respective headers somewhere in the include path. This is explained in detail in README.rst.

Libyang 2 and sysrepo 2 support is planned in #12

[nullromo]

Thank you for pointing that out. I somehow glossed over that error message.

This is explained in detail

I don't see anything about libyang and sysrepo version compatibility in the readme. It just explains what to do for non-standard installations.

But anyway, thanks for responding and clarifying.

[rjarry]

Indeed that compatibility info is missing. I will add this tomorrow and maybe try to get better explicit errors
