meson_python build failure - missing directory?

[Randall Rathbun]

I have been able to successfully build 77 packages (of the 196 slated to be built for sage 10.2) but now encountered a strange error with meson_python.

I went to the appropriate directory, opened up a subshell and tried to rebuild the package.

owner@localhost:~/math/sage-10.2/local/var/lib/sage/venv-python3.11.1/var/tmp/sage/build/meson_python-0.14.0> cd '/home/owner/math/sage-10.2/local/var/lib/sage/venv-python3.11.1/var/tmp/sage/build/meson_python-0.14.0' && '/home/owner/math/sage-10.2/sage' --buildsh

Starting subshell with Sage environment variables set.  Don't forget
to exit when you are done.  Beware:
 * Do not do anything with other copies of Sage on your system.
 * Do not use this for installing Sage packages using "sage -i" or for
   running "make" at Sage's root directory.  These should be done
   outside the Sage shell.

Bypassing shell configuration files...

Is this an install package script oversight?

[Matthias Koeppe]

Send config.log please

[Randall Rathbun]

Here are some log and config files and my record of what I did to re-do the build from scratch. The build stopped again on the 77th package to be installed, meson_python, with the same error.

[Matthias Koeppe]

From config.log:

# ------------------------------------------------------ ##
## Checking whether SageMath should install SPKG meson... ##
## ------------------------------------------------------ ##
configure:37902: checking for meson >= 1.2.0
configure:37986: result: /home/owner/.local/bin/meson
configure:37997: will use system package and not install SPKG meson

I'd suggest to check where /home/owner/.local/bin/meson is coming from and if the problem goes away if you either remove /home/owner/.local/bin from PATH and re-run "configure", or alternatively use "./configure --without-system-meson".

[Randall Rathbun]

Again, an automatic software update via the system must have installed meson as part of the update. I have scrubbed my local version. I wonder how many other autoupdates from openSuse are interfering with sage v10.2 install? I do NOT remember installing meson at all.

[Randall Rathbun]

Matthias

Thanks for all your help. Even after I used yast2 to remove meson, it still did NOT remove meson from my ~ .local/bin location and I had to manually remove this. This is frustrating when the system package manager will NOT remove the executables upon command leaving the administrator believing that the files were removed.

Randall

[Matthias Koeppe]

What is in ~/.local is typically not installed by the distribution's package manager (even on OpenSUSE). It may have been installed by using `pip install --user`.

[Randall Rathbun]

I believe you are correct, thanks.

[Randall Rathbun]

the ipython builder insists that the ipython log file must be included so the information about a dependency can get back to the developers.

so it is attached to this reply

[Matthias Koeppe]

Thanks! Fixed in https://github.com/sagemath/sage/pull/37227
