McCLIM build fails

[lukego]

McCLIM build is not working. I don't understand exactly why yet.

There seem to be a couple of issues:

• [x] mcclim-bezier package is being flagged as broken. (I see now this was done manually, possibly due to problem below.)
• [ ] mcclim-bezier package fails because it tries to compile a file from mcclim-render into read-only nix store.

Reproduce on master branch:

$ lwp sbcl mcclim-bezier
error: builder for '/nix/store/1nhzagh6w25zsy2vzfmf128yvs654jfv-mcclim-bezier-20221106-git.drv' failed with exit code 1;

Thinking aloud...

The mcclim-render package seems to compile fine including Extensions/render/package.fasl:

[luke@snowy:~/git/nix-cl]$ nix build .#sbcl.pkgs.mcclim-render
warning: Git tree '/home/luke/git/nix-cl' is dirty

So it seems like mcclim-bezier is somehow attempting to recompile mcclim-render in a nix store directory where it is already precompiled? That's a new one for me :)

mcclim/render depends on mcclim-fonts/truetype : Quicklisp ignores slashy systems in dependencies ,so we have to put it there manually

I got something to build using this patch, I don't know how to test it though:

Thanks!

That patch builds for me, I'll let you know how it goes in practice.
