[gtk-osx-devel] Problems with gtk-osx-setup.sh - M1

[Spock <spock rogersfamily me uk>]

Hi, I’m running gtk-osx-setup.sh on an M1 Mac/MacOS 12.2 and am having a couple of problems ...

First off, I’m running without any homebrew paths in any of the environment variables.

Now, with this shell, when I run the script, I get the following:

— snip ----
pyenv: pip: command not found

The `pip' command exists in these Python versions:
  3.10.0

Note: See 'pyenv help global' for tips on allowing both
      python2 and python3 to be found.
pyenv: pip: command not found

The `pip' command exists in these Python versions:
  3.10.0

Note: See 'pyenv help global' for tips on allowing both
      python2 and python3 to be found.
—- snip ---

So I add a line to the script to allow it to find python:

— snip —
PIP=“$PYENV_ROOT/shims/pip”
# Point pyenv at the 3.10.0 Python ...
$PYENV local 3.10.0
$PIP install --upgrade --user pip
— snip ---

With this line, I remove the artefacts from the previous build and re-run. This time the script completes, so 
I move on to “./.new_local/bin/jhbuild bootstrap-gtk-osx which appears to complete successfully.

*** Was this the right thing to do?

The final step “jhbuild meta-gtk-osx-bootstrap meta-gtk-osx-gtk3 fails due to problems finding a version of 
ninja …

— snip ---
gtk-doc 1.33.1

  User defined options
    libdir     : lib
    prefix     : /Users/j/gtk/inst
    wrap_mode  : nofallback
    tests      : false
    yelp_manual: false


ERROR: Could not detect Ninja v1.8.2 or newer
— snip ---

I checked the version installed by the script …

— snip ---
j@pauls-mbp ~ [nobrew] % ./.new_local/bin/ninja —version
1.10.2
— snip ---

*** So what is happening with ninja? Is there a setup step I’m missing?

Any help much appreciated!
