Comment: the error relates to the missing 'pkg-config' file or directory, while it seems that it should be 'pkgconfig' (without the dash).

Please read the docs, start at the top of the page:

https://borgbackup.readthedocs.io/en/stable/installation.html

Thanks for pointing me to the proper doc page.

I got confused mostly by the similarity of the names of the packages:
the page "https://github.com/borgbackup/borg/releases?page=1", section "[Release 1.2.4]" tells "use: pip install pkgconfig", which I did, and the error encountered by me indicated missing package "pkg-config".
Seeing so similar names I was thinking that there is a spelling error in the script and I haven't investigated further. My bad !

Again, thanks for your quick help :-)

Borg installed, case closed :-)

Just in case anybody stumbles upon this:
There is probably a package from your distribution called pkg-config, pkgconf et ecerta AND a python package called pkgconfig. The Python pkgconfig is a wrapper/binding for your system's pkg-config. Install both.

[ThomasWaldmann]

Since we have the pyproject.toml file, the python pkgconfig package should get installed automatically when using a recent enough version of pip:

https://github.com/borgbackup/borg/blob/master/pyproject.toml

https://github.com/borgbackup/borg/blob/1.2-maint/pyproject.toml

One still needs to have the pkg-config CLI tool installed though.

Would it make sense to use cibuildwheel to provide wheels for some manylinux versions?
