Basic dynlinking test. Question here ocsigen/js_of_ocaml#1196 This was added as a pull request to jsoo tests here https://github.com/ocsigen/js_of_ocaml/pull/1197/files (interesting dune file)
So ultimately maybe the thing I was missing with Sys.interactive := false with all the dynlink and toplevel options and initialization. How would I have found that?
If I try to just use --dynlink +dynlink.js
>> Fatal error: Toplevel bytecode executable is corrupted
Fatal error: exception Dynlink_compilerlibs.Misc.Fatal_error
If I try to include toplevel with --toplevel +toplevel.js
Fatal error: exception Failure("Toplevel not initialized (toplevelCompile)")
If I initialize Jsoo.toplevel
Fatal error: exception Invalid_argument("The dynlink.cma library cannot be used inside the OCaml toplevel")
Other approach using Seperate compilation, not better
js_of_ocaml main.cmo
js_of_ocaml ~/.opam/4.12.1/lib/ocaml/stdlib.cma -o stdlib.js
js_of_ocaml build-runtime -o runtime.js
js_of_ocaml link runtime.js stdlib.js main.js -o a.js
