Hello ECL Devel! I just wanted to write in and report on some nice success I've had over the past year, getting my project to run and compile with ECL such that I can use Godot to build a new front end for it. My project is a nearly 40 year old project called Boxer [1] that has gone through numerous platform ports and rendering layer updates (all the way through symbolics machines up through macs/windows etc). Currently the stable build uses Lispworks and OpenGL on macOS, recently I had updated the rendering from using old school openGL to more modern shader based openGL. However, I'm not really a professional graphics programmer and was looking for a way to get more multimedia things for free and as well and cross platform support. After prototypes with lots of different toolkits, I've been using Godot to build the next visual frontend on the core functionality and it's been fun using ECL to do this, although it has been arduous getting here! :) Part of the reason I chose both Godot and ECL as the lisp distribution to switch to, is that they both support WASM, which is incredibly important for me going forward, Kudos to all of Daniels work on the web assembly. After copious refactoring and hacking, I've been able to build a shared library version of all my core functionality to use in a GDExtension with Godot, as well as a static library version to use in the WASM version with Godot (and my GDExtension hacked up a bit to be a core Godot module). And it works! Pretty well, I have a number of rough edges to work out, but I'm very excited about this going forward. I know the WASM stuff is still a moving target, and I'm interested in hearing about how the compiling mechanism will be standardized a bit more in core. For building a shared library I'm using our asdf:make-build, and to build the static library targetting WASM I'm using the asdf-cc.lisp copied from Daniels wecl repo. At the moment I have my Godot front end with ECL extension working on macOS, Linux, and Web. At the moment trying to finagle the iOS version. Let me know if anyone has any questions, comments. Certain parts of this were quite difficult to wrangle so I am hoping to perhaps contribute back some documentation or something. Thanks everyone for all your hardwork on ECL, and making it as mutliplatform as possible, especially including WASM, it's a real gem of a project! :) Cheers, Steve [1] https://github.com/boxer-project/boxer-sunrise
