Target 'mwpvlib' has 1 outputs: ['libmwpvlib.a'], but only 3 "install_dir"s were found.

meson build --buildtype=release --strip --prefix /usr, output the errors as "Target 'mwpvlib' has 1 outputs: ['libmwpvlib.a'], but only 3 "install_dir"s were found."

How to fix it?

Operating system and version?

[koklimabc]

ubuntu 23.10

Thanks. I have 22.04 and 24.04 here.
The reason is that Ubuntu 23.10 ships quite an old meson compared to the release of the OS.
The behaviour of meson changed in regard to the generation of libraries sometime between meson 1.2.0 and meson 1.3.0 (their release notes are good, bit not that granular). mwp checks for 1.2.0 to assess this change of behaviour; it is now apparent that 1.2.1 still has the old behaviour.

I've update the development branch on github?
Can you pull, checkout and build and see if that fixes the issue and let me know?
Ask here is you need help with getting development branch.

Fixed in master 2024-04-27 (4966e9f)

Yes already fix :), I build from source on ninja-1.12.0 version (then transfer it into '/usr/bin/ninja') and using meson 1.4.0 (BTW I do create separate environment (known as 'venv') to install latest meson version - pip install meson, refer 'https://askubuntu.com/questions/1465218/pip-error-on-ubuntu-externally-managed-environment-%C3%97-this-environment-is-extern').

meson build --buildtype=release --strip --prefix /usr
cd build
ninja install

And finally it work. Thanks very much to your reply :) .

OK, but I already know that 1.4 works ... it would have been nice to confirm that bumping the version check fixed it on 23.10.
But never mind ...
