RuntimeError: Could not determine how to run Meson. Please file a bug
with details.
I'm currently using Guix on top of Fedora 26. The installed version of
meson is 0.44.0.
* Possible cause:
From /mesonlib.py/: line 47~51, we have:
#+BEGIN_BLOCK python
# The only thing remaining is to try to find the bundled executable and
# pray distro packagers have not moved it.
fname = os.path.join(os.path.dirname(__file__), '..', 'meson.py')
if not os.path.exists(fname):
raise RuntimeError('Could not determine how to run Meson.
Please file a bug with details.')
#+END_BLOCK
which means meson will try to find the meson.py script at startup, but
it seems Guix has renamed the this file with the new file name
*.meson-real* and warp it with a shell script /meson/ in bin.

[Message part 1 (text/plain, inline)]
We need to have a look at the whole `detect_meson_py_location()`, not
only on lines 47 to 51.
detect_meson_py_location() assumes the executable to be called "meson"
or "meson.py", but in guix it currently is called ".meson-real" (see teh
first entry in the trace-back).
The solution would be to get rid of the wrapper-scripts, see
<https://lists.gnu.org/archive/html/guix-devel/2017-11/msg00041.html>
A work-around would be to substitute in file mesonbuild/mesonlib.py
meson_command = python_command + [detect_meson_py_location()]
by
meson_command = python_command + ["$OUT/bin/meson"]
(you got the idea, I assume). Of course we should verify
detect_meson_py_location() is not used elsewhere and consider renaming
that function to "disable" it.

Sounds reasonable. Does it work for you? If so, could you provide a
patch?

I don't have any cards in this game and not time for working on it ATM,
I just did the analysis.

I am sorry to let you down, but I dont have any time for developing on guix
at the moment :/ and by the way, I am not, and have never considered myself
a user of meson, I just wanted the buildsystem in guix because I noticed
that gnome was starting to use it :)

Or in this case, python script, we can change the wrapper script into something
like this:
#+BEGIN_SRC python
import os
os.environ['PYTHONPATH']="/gnu/store/.../site-packages${PYTHONPATH:+:}$PYTHONPATH"
exec(open("/gnu/store/n53zdnl4l3gm9sg15bfwxp0wdrwrvhg4-meson-0.44.0/bin/.meson-real").read())
#+END_SRC
or
#+BEGIN_SRC python
import os
os.environ['PYTHONPATH']="/gnu/store/.../site-packages${PYTHONPATH:+:}$PYTHONPATH"
exec(compile(
open(
"/gnu/store/n53zdnl4l3gm9sg15bfwxp0wdrwrvhg4-meson-0.44.0/bin/.meson-real".read(),
"/gnu/store/n53zdnl4l3gm9sg15bfwxp0wdrwrvhg4-meson-0.44.0/bin/.meson-real",
'exec'
)))
#+END_SRC

Sorry about that, this section is wrong. Here is the correct one. Be careful with the "..."
in the environ assignment. I omitted part of the path due to it's too long.
#+BEGIN_SRC python
#!/usr/bin/env python3
import os
os.environ['PYTHONPATH'] = "/gnu/store/.../site-packages${PYTHONPATH:+:}$PYTHONPATH"
# exec(open("/gnu/store/n53zdnl4l3gm9sg15bfwxp0wdrwrvhg4-meson-0.44.0/bin/.meson-real").read())
exec(compile(
open(
"/gnu/store/n53zdnl4l3gm9sg15bfwxp0wdrwrvhg4-meson-0.44.0/bin/.meson-real"
).read(),
"/gnu/store/n53zdnl4l3gm9sg15bfwxp0wdrwrvhg4-meson-0.44.0/bin/.meson-real",
'exec'
))
#+END_SRC
And the wrapper should be named as "meson", in this case.
The above code set the environment variables and execute the corresponding code
by loading it(not spawning a new process). Hence the argv will be preserved.

Sure, though Hartmut’s solution looked even simpler.
BTW, Ricardo has posted a patch on this topic here:
https://bugs.gnu.org/29951
We could use it here (it won’t be merged until the next ‘core-updates’
cycle), but if there’s a simpler solution, we should probably go for
that.
Thanks,
Ludo’.

Using Guix on the top of Debian and running:
--8<---------------cut here---------------start------------->8---
guix environment -C --ad-hoc meson
meson --version
--8<---------------cut here---------------end--------------->8---
works for me with Guix 73e7a42. Is it still an issue for you?
Since the commit 0fb9a8df429a7b9f40610ff15baaff0d8e31e8cf is merged on
master – if I read correctly – the issue should be fixed.
What is the status of this bug?
All the best,
simon
