Thanks. That might require some (dynamic) probing. IIRC the OpenGL library/driver situation was different from distribution to distribution (and just needlessly confusing in general). Maybe someone has worked up a general solution to this particular problem, and if so Racket could adopt that. Amazingly, Nix has already solved many such weird issues. If this Racket/Nix effort goes forward, Racket users will probably need some guidance (and discipline) regarding foreign libraries. -- Anthony Carrico -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

I'm able to build the drracket package without any error conditions occurring along the way, but: - The resulting drracket package is empty. :-D - I'm not actually building the packages, just installing them (raco pkg install --no-setup). - There is a lot of cleaning up to do in the nix expressions, the low-hanging fruit being e.g. redundant dependency listings -- drracket has over 1500 dependencies, but a simple sort -u on them reveals that they are actually only 135. - It probably doesn't put any stuff in .../bin . My next step is dogfooding racket2nix: Put the logic in a library, generate a thin wrapper that calls it, add rackunit tests, make a man page, etc. Hopefully this will teach me enough about packaging that I can go back and work toward a working drracket package. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

This is great Claes, and as I said on IRC, I hope we can eventually
collaborate... as some others know I'm hoping to get more Racket
packages into Guix... which is like Nix, but written in Scheme!
But that work will probably build on experiences from this Nix work if I
get to it first at all (and it sounds like you might beat me to it
anyway) ;)
Thanks for working on this!

Re opengl: I recall running into a similar problem, I eventually scrapped the opengl dependency but it might be possible to wrap the whole thing up in a makeWrapper then pass in the opengl executable path for non-nixos systems into it. The reason, I believe, is that opengl is packaged as a static library and not a dynamic lib.

I'll try that. It worked! So now it even complains when I try to install base against a full racket, that base already exists. This is a good thing. :-) But when I'm installing against minimal I get: /nix/store/rm4jgl2jhdmv0b2jlr2jmziih8clximf-racket-minimal-6.12/bin/racket -G /nix/store/gfwrnnq5ql1b35i03cs3xyzrflcrapfi-base/etc/racket -U -X /nix/store/gfwrnnq5ql1b35i03cs3xyzrflcrapfi-base/share/racket/collects -S /nix/store/rm4jgl2jhdmv0b2jlr2jmziih8clximf-racket-minimal-6.12/share/racket/collects (current-library-collection-links): (#f /nix/store/rm4jgl2jhdmv0b2jlr2jmziih8clximf-racket-minimal-6.12/share/racket) (find-library-collection-links): (#f /nix/store/rm4jgl2jhdmv0b2jlr2jmziih8clximf-racket-minimal-6.12/share/racket) (find-links-file): /nix/store/gfwrnnq5ql1b35i03cs3xyzrflcrapfi-base/share/racket/links.rktd (current-library-collection-paths): (/nix/store/gfwrnnq5ql1b35i03cs3xyzrflcrapfi-base/share/racket/collects /nix/store/rm4jgl2jhdmv0b2jlr2jmziih8clximf-racket-minimal-6.12/share/racket/collects) (find-library-collection-paths): (/nix/store/gfwrnnq5ql1b35i03cs3xyzrflcrapfi-base/share/racket/collects) (find-pkgs-dir): /nix/store/gfwrnnq5ql1b35i03cs3xyzrflcrapfi-base/share/racket/pkgs (get-pkgs-search-dirs): (/nix/store/rm4jgl2jhdmv0b2jlr2jmziih8clximf-racket-minimal-6.12/share/racket/pkgs) collection-file-path: collection not found collection: "setup" in collection directories: /nix/store/gfwrnnq5ql1b35i03cs3xyzrflcrapfi-base/share/racket/collects So (current-library-collection-paths) reports both base/.../collects and racket-minimal-6.12/.../collects.

One nice thing you can do once you have racket2nix is that you can have your racket package generated as a nix package, and then override the nix package to have native dependencies, which I hope will be very helpful to people in your situation in the future. -- /c -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

I'll try that. I thought packages were always looked up through the collections, but maybe that's a difference between package dependencies when installing and the way you look them up when you refer to them in the code? -- /c -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

I think this is also the right idea, but I think you need to set 'pkg-search-dirs in parallel to 'links-search-files within "config.rktd". The two separate entries reflect how the package system is built on top of the collection-link layer, but it has to keep additional information that is specific to the package layer. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Re: racket2nix
I use Nix, but mostly for Haskell currently, rather than Racket. I did prototype a nix project with Racket. I don't have the sources at my fingertips. I'll report if I look back and see anything helpful for you. It looks like you are trying to tie into the Racket package system. We didn't try to do so, we were just trying to go from a git clone to a common development environment in one step. I do remember modifying the racket derivation in the nixpkgs repo. I don't think that got pushed upstream. The Racket derivation needed to be parameterized to find the opengl libs/drivers. I also remember that I couldn't get this to work reliably on any OS except NixOS. Any opengl program was going to have similar trouble since the libs are a function of the drivers which can't really be provided by Nix on non NixOS platforms. This situation was more of a reflection on the state of OpenGL than Nix in my opinion, but we ended up developing in a NixOs vm for this reason only.
