Hello, I've been able to successfully (mostly) build pil21 on Windows 10 using MSYS2.
There are a few caveats that should be fixable: * requires bootstrapping from Linux to produce *.ll files * builds statically-linked currently * libreadline disabled - linking issues (so no builtin REPL) * ext and ht libraries not building - clang/preprocessor issues * only msys-2.0.dll (LGPL) needed when distributing the picolisp binary I haven't fully tested it yet (the infamous fork appears to work!). There is no builtin REPL so when invoking the picolisp binary, users should use the CLI as usual and pass picolisp files to load, or implement a REPL in PicoLisp ;) https://github.com/Seteeri/pil21-win Kevin
