Re: [gambit-list] A Lisp that runs on Wasm?

Thanks to all the responses in this thread for your advice—John Cowan, Faré, Amirouche.

I'll investigate Chibi Scheme.

Chibi Scheme and Spock both run in the browser. You can build Chibi Scheme with a WASM target; Spock is written in JavaScript.

I'm searching for a way to write Lisp and have it run on a web browser as WASM, i.e. avoiding JS. I was hoping Gambit Scheme might be the key, by compiling Lisp —> (Gambit compiler) —> C —> (Clang) —> wasm. But I'm encountering problems. My current issue is the 'gambit.h' file checks for lots of things including `setjmp` which doesn't exist in WASM. Below is my test situation. Does anybody think this endeavor of compiling Gambit -> wasm can work? Or are there any other ways to write Lisp and execute it as Wasm?

;; fib.scm
(define (square x)
  (expt x 2))

% gsc -c fib

produces a fib.c file. Then:

% clang --target=wasm32 -O1 -Wno-deprecated-declarations -Wno-unused -Wno-write-strings -Wdisabled-optimization -fwrapv -fno-strict-aliasing -fno-math-errno -fomit-frame-pointer -fPIC -fno-common -D___SINGLE_HOST -D___DONT_HAVE_MATH_H -D___DONT_HAVE_SETJMP_H -D___DONT_HAVE_SIGNAL_H -D___DONT_HAVE_WCHAR_H -I"/opt/homebrew/Cellar/gambit-scheme/4.9.3_2/v4.9.3/include"  fib.c

Gives this error:
