Can't compile under macos with python 3.13

[Cezanna]

$ python3 --version
Python 3.13.4
$ uname -nrm
xxxxx 25.2.0 arm64

and from a previous post to compile with python 3 under macos

$ CPPFLAGS="-I/opt/homebrew/Cellar/exiv2/0.28.2/include -I/opt/homebrew/Cellar/boost/1.85.0/include"
$ LDFLAGS="-L/opt/homebrew/Cellar/exiv2/0.28.2/lib/ -L/opt/homebrew/Cellar/boost-python3/1.85.0/lib"
$ BOOST_LIBDIR=/opt/homebrew/Cellar/boost/1.85.0/lib/
$ export CPPFLAGS LDFLAGS BOOST_LIBDIR

I got this error :

$ pip3 install --break-system-packages --no-binary :all: --no-cache-dir py3exiv2

note: This error originates from a subprocess, and is likely not a problem with pip.

I will appreciate any help..

The solution was to modify the LDD and CPP flags to reflect my system.
