Stencyl Nix package? #24487

Closed dhruvio closed 6 years ago

dhruvio commented 7 years ago

I'm new to NixOS (running 17.03), and I'd like to install Stencyl. It is a game engine. There are installation instructions available for Debian-like systems here, but I'm not sure how to source the correct dependencies for NixOS. Would anyone be able to help me set up a stencyl/default.nix package? It would be great if we could merge this upstream too.

translated from this guide: http://community.stencyl.com/index.php/topic,32022.0.html

You will also need to use callPackage_i686 instead of callPackage (since 32-bit only support). jdk8 is also in nixpkgs. Since it seems to be a proprietary package, you probably also need to set the library path manually like in this package: https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/security/gorilla-bin/default.nix#L30

Cool, thanks @Mic92. I'm going to give writing the nix file a go.

Update:

I managed to get Stencyl running in my environment. I've included the default.nix file below; here are the steps I took to get it working:

Any other ways I can improve this?

Jdk probably does not belong to library path. If it is needed usually there is a shell script calling java.

dhruvio commented 7 years ago

@Mic92 you're right, Stencyl comes with its own java executable. However, I ran into a problem using it -- I kept getting an error no such file or directory with no other information. Changing to java fixed that problem and started Stencyl. However, trying to build a game inside Stencyl fails due to a similar error when running the bundled haxe and haxelib executables: no such file or folder with no further information. I'm not sure how to move forward -- callPackage_i686 doesn't affect the outcome either. Any thoughts?

dhruvio commented 7 years ago

So, I've made some progress. I'm now using patchelf to reassign the interpreters for the bundled executables with one in the Nix store. Below is my updated default.nix file.

I am getting an error now though, in which a bundled executable, $out/share/stencyl/plaf/haxe/haxelib, fails to run due to a missing shared library, $out/share/stencyl/plaf/neko-linux/libneko.so. The shared library is bundled with Stencyl; I'm not sure how to fix this error. Any ideas @Mic92 ?

Can you add this as a pull request? Then it is easier to comment or edit. You either need to extend LD_LIBRARY_PATH or expand rpath with patchelf to include share/stencyl/plaf/neko-linux.

@Mic92 PR is up: https://github.com/NixOS/nixpkgs/pull/24881

dhruvio commented 6 years ago

Closing issue as I can't get the bundled Haxe dependency working correctly. Nixpkgs has a version of Haxe whose source is modified, and it is unclear how to integrate that with Stencyl. Hopefully someone with better knowledge of Haxe will be able to add this package to the repo.
