When I try to use meson with kdevelop I always get error messages like: /home/../project> /usr/lib64/python-exec/python-exec2 --reconfigure /home/../project/build /usr/lib64/python-exec/python-exec2: python-exec2 is a wrapper, it must not be run directly. *** Failure: Exit code 127 *** The problem arises because kdevelop seems to resolve symlinks itself before running the corresponding executable. But on gentoo systems python-scripts are all symlinks to python-exec. When kdevelop resolves the symlink /usr/bin/meson->/usr/lib64/python-exec/python-exec2 the original name is lost and python-exec doesn't know that to do. Solutions: Kdevelop shouldn't resolve the symlink itself.
End of year 2020 The problem still exists. Gentoo /usr/lib/python-exec/python-exec2 --backend ninja /home/.../project/build /usr/lib/python-exec/python-exec2: python-exec2 is a wrapper, it must not be run directly *** Failure: Exit code 127 ***

Is there any temporary workaround?
(In reply to Petros from comment #2) > (In reply to Ihor Antonov from comment #1) > Is there any temporary workaround? Yes. After reading meson quick start guide I learned that meson can be used directly from its git repository: https://mesonbuild.com/Quick-guide.html#installation-from-source So I cloned https://github.com/mesonbuild/meson into some directory and pointed KDevelop at meson in that directory --------------------- WORKAROUND: 1. clone https://github.com/mesonbuild/meson 2. in KDevelop when setting up meson project use meson.py that you obtain at step #1 as meson binary

Can anyone verify that https://invent.kde.org/kdevelop/kdevelop/-/merge_requests/251 fixes this issue?

Git commit 2f723c977906582ddca5c0a710791e25bc35a51b by Bernd Buschinski. Committed on 04/12/2021 at 21:39. Pushed by buschinski into branch 'master'. Fix meson executable - on my system meson is a link to python2-exec $ ls -ld $(which meson) /usr/bin/meson -> ../lib/python-exec/python-exec2 The python2-exec must not be executed directly. - Currently the mesonExecutable is canonicalized, which also resolves symlinks This causes the meson plugin to execute stuff like: $ python2-exec --reconfigure instead of $ meson --reconfigure Fix this by not canonicalizing the mesonExecutable, validity is already checked earlier.
