The error which causes the build failure :

Traceback (most recent call last):
File "/usr/bin/g-ir-scanner", line 99, in <module>
from giscanner.utils import dll_dirs
File "/usr/lib64/gobject-introspection/giscanner/utils.py", line 385,
in <module> import distutils.cygwinccompiler
ModuleNotFoundError: No module named 'distutils'

As you can see, that's a python problem.
The build log also indicates that is uses python3.12 in several places :

/usr/bin/python3.12

Your emerge --info :

dev-lang/python: 3.12.7_p1::gentoo, 3.13.3_p2::gentoo

Yes, that's wrong.

Why do you have two versions of python ?

I didn't know I had.

Have you finished the python 3.13 migration ?

I believed I had.

Why does it use by default python 3.12 instead of 3.13 ?

I don't know.

I suspect that if you set python 3.13 as the default python interpreter
on your system, the gtk build system will find the 'distutils' module
and the build will succeeds.
You should check that your system is up-to-date
and you should fully upgrade to python 3.13.

I've had a look round
& can't see how to correct the line above in 'emerge --info'.
'make.conf' has :

#USE_PYTHON="3.10 3.11"
#PYTHON_TARGETS="python3_11"
#PYTHON_SINGLE_TARGET="python3_11"

'package.use' has :

# for Python-3.12 : Portage shd apply these auto'ly
#*/* PYTHON_TARGETS: -* python3_12
#*/* PYTHON_SINGLE_TARGET: -* python3_12

Commenting those 6 lines should have left it to Portage to use 3.13 .
What am I missing ?

Thanks for your very prompt reply (smile).

If the python 3.13 migration is done and your system up-to-date, and
python 3.12 is not required anymore on your system, then an emerge
--depclean should remove it automatically and switch the default
interpreter to python 3.13.
What is the output of following commands :

# emerge -pvuDU @world
# emerge --depclean --pretend

Another way is to manually switch the default interpreter to 3.13, but
I would not recommend it, since emerge should do it automatically if
everything is solved and ok. See /etc/python-exec/python-exec.conf

and switch the default interpreter to python 3.13.
What is the output of following commands ? --

# emerge -pvuDU @world
# emerge --depclean --pretend

The latter listed 8 pkgs which needed to be updated with Python 13 ;
when I had done that, the emerge of 'gtk+' compiled without a problem.

Another way is to manually switch the default interpreter to 3.13,
but I would not recommend it, since emerge should do it automatically
if everything is solved and ok : see /etc/python-exec/python-exec.conf

Thanks : I've commented 'python3.11' there & added a line 'python3.13'.

In 22 yr using Gentoo, I've never done 'emerge world' without '-pv',
but instead updated one or a short list of pkgs manually.
Hence my 'world' file doesn't contain all the pkgs I want
& 'emerge --depclean' wants to remove far more files than is needed.

Thanks again for your help, which was very accurate (smile).
