Developer installation crashes deep inside poetry -> meson with pygobject about gaphor HOT 6 CLOSED

"Can I possibly ignore the lock file?"
I renamed poetry.lock to poetry.lock.original
3 packages ran additional updates, then it crashes at the same spot in pygobject.

Hi @ghillebrand, sorry you are having issues. If you are getting a GCC error, that's not good and we should figure out why and not try to patch around it. Gvsbuild uses MSVC, and there should be no GCC.

Were you able to successfully install GTK using the Gvsbuild zip?

Hi,
So, I don't know why it wanted a C/ C++ compiler, but it did. I installed the 32bit gcc without thinking/ realising. That was what was causing the error. I'm fairly sure the 64 bit gcc would have solved things, but to be sure, I hooked down the 5GBs of VS and C++ environment.

The wingtk instructions make it clear that you will need MS VS's dev env if you are building gvsbuild. I would have thought that using the latest gtk build as per instructions would "just work", but poetry was doing something with it. Their link didn't include a C++ compiler, but I added it for good measure.

Now, everything runs. I might be a bit unusual as a dev not having a C++ compiler on my path. I have one now!

So all good. Now, to figure out gaphor.
What is a good place to explore the ideas/ direction I need to implement a new model type (higraphs)? I have a bunch of newbie questions.

Thanks for the prompt response and help

Hi @ghillebrand,

The matrix channel at https://matrix.to/#/#gaphor_Lobby:gitter.im is one place. The discussions here, on GitHub is another place, we the discussion can be a bit more structured.

I tried to document it as good as possible on https://docs.gaphor.org/en/latest/modeling_language.html, so it would be good to start there.

PS. PyGObject is indeed a tricky dependency, since it requires a C compiler. The way it works make it particularly tricky, since it does not allow itself to be easily packaged as a wheel. It's our only C dependency, luckily 😃 .

I shall spend some time looking at the documentation and the code, and getting a feel for "the lie of the land". I suspect then that creating a thread around "Creating a Higraph model type" or something might be the way to go.

ITO the C dependency, I think a note in the (otherwise very comprehensive!) instructions might be good. I strongly suspect that the the 64bit gcc would do the trick, and a version like this doesn't seem to need any admin rights? I pulled down the 5GB MSVS, but it seems like overkill!

Thank you for running supportive, positive little community here.

OP is happy that everything is resolved.
