bonsai Can't build the hello

Hi,

I'm trying to get started with the hello_world example, but when I try to build it I'm getting the following error

dune build ./main.bc.js

Entering directory 'path/to/bonsai'
File "web/dune", line 4, characters 18-47:
4 |   bonsai_protocol incr_dom.javascript_profiling)
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error: Library "incr_dom.javascript_profiling" not found.
-> required by library "bonsai.web" in _build/default/web
-> required by executable main in examples/hello_world/dune:1
-> required by _build/default/examples/hello_world/main.bc.js

As far as I can tell, incr_dom is installed. I've also tried adding the janestreet repository to my current opam switch, but the same error persists.

I'm using Ocaml 4.13 on WSL/Windows. Opam list: https://gist.github.com/joanimato/55207a2352daa16c142b052342b8231a

could you make an empty switch, add the janestreet repository to it, and then install bonsai again?

Sorry for the late reply. For some reason I'm not receiving notifications on these....

Still not working. I even tried it on a Mac this time and got a similar error.

List of commands:

opam switch create ./ --empty
opam repo add janestreet-bleeding https://ocaml.janestreet.com/opam-repository
opam install bonsai
dune build ./main.bc.js

the output that I got was:

Entering directory 'path/to/bonsai'
File "web/dune", line 4, characters 18-47:
4 |   bonsai_protocol incr_dom.javascript_profiling)
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error: Library "incr_dom.javascript_profiling" not found.
Hint: try:
  dune external-lib-deps --missing ./main.bc.js

I tried the command in the hint and it doesn't seem to do anything.

I was able to resolve the issue by using the standard opam repository with Ocaml 4.13 installed. I was initially confused because I expected the build folder to be inside the hello_world directory, but it actually appears at the root folder of the repository. Once I figured that out, the hello_world example compiles fine.

Some of the examples still gave me dependency issues (like "bonsai_web_ui_panels_experimental" or "piecewise_linear_kernel" not found...), but I was able to build most of them.

I was trying to build dygraph example but I can't find Piecewise_linear_kernel.Make_invertible anywhere, where can I find it to build this example?

Can't build the hello_world example.
