Re: [gtk-osx-users] GTK+ macOS: fontconfig



Neither. Pipenv provides that particular bit of magic.

Pyenv gets us Python3, in which we must run jhbuild in order to use meson. Pip makes it simple to add python-based tooling like six and meson. Pipenv pulls the two together, greatly simplifying the configuration: If your project needs something else from Pypi you can just add it to your Pipfile and Pipenv will take care of installing it for you at startup.

Great, thanks John.

I'll configure it manually through the shell for now.

I had a look at `new-setup.sh'; very succinct and elegant. Is it an aspect of pip or pyenv that provides the voodoo to automatically install missing python modules?

The way I intend to resolve the problem with PIP modules going forward is in https://github.com/jralls/gtk-osx-build/tree/pipenv. No-one on the list seems terribly interested in that though, so when I get bit of bandwidth I'll just finish it up and merge it to master.

In the meantime the simplest thing to do is to build python and then run the following commands in a jhbuild shell:
  python -m ensurepip
  pip install six

Once six is installed you can build meta-gtk-osx-bootstrap and whatever else you need.
