I'm trying to install libtorrent with python3.12 on macOS Monterey. Here's how I install dependencies according to the docs:
brew install boost-build boost [email protected]
Then I do:
git clone --recurse-submodules https://github.com/arvidn/libtorrent.git
cd libtorrent
export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
python setup.py bdist_wheel # or python setup.py build
whichever command is used, it runs for a few minutes then gives the error below (truncated for character limit):
% python setup.py bdist_wheel
running bdist_wheel
b2 version: (1, 5, 2, 1)
running build

This message suggests that boost python is missing:
ld: library not found for -lboost_python312
You also need to install boost-python:
brew install boost-python3
Libtorrent's build script will assume the name of the library be boost_python<major><minor> That's "312" in your case.
