Description

See this repo:

https://github.com/rgrinberg/jbuilder-c-stubs

[rgrinberg:~/tmp/c-ocaml] 1 % jbuilder build hello_world.exe
[rgrinberg:~/tmp/c-ocaml] % _build/default/hello_world.exe
Hello
[rgrinberg:~/tmp/c-ocaml] % _build/default/hello_world.bc
Fatal error: cannot load shared library dllc_lib_stubs
Reason: dllc_lib_stubs.so: cannot open shared object file: No such file or directory

Am I doing something wrong here?

Research direction

Reproduce the example from https://github.com/rgrinberg/jbuilder-c-stubs with jbuilder build hello_world.exe, then run both the native executable and _build/default/hello_world.bc. Trace how the C stub shared library is built and located for bytecode; done means the expected bytecode invocation works or the required invocation and limitation are clearly documented.
