Hello! I’m writing a library in racket and I’ve got a strange error message on building the library:

write: cannot marshal value that is embedded in compiled code

I’ve googled a bit about this error message but it provides me no clue on how to solve it.

This error happens only when building the library on github CI service

it does not happen when running the test cases on my desktop machine

any pointers would be really helpful.

Have you seen this? https://lists.racket-lang.org/dev/archive/2012-July/010101.html

It might give a clue wrt what to look for.

It is odd, that you don’t get an error on both machines - unless the issue is that you are generating some value in your own machine that can’t later be read by the instance on the CI service.

Hi!

Yeah, that’s weird.

The library is a simple language

and I manage to get some tests running on the interpreter

but whenever I push the code on github, it runs the CI service and returns the error message

It’s an uncommon error, so it hard to guess what is wrong.

By “interpreter” do you mean your own?

No, in racket interpreter

the code runs just fine

I’ll try to add the prefab thing to the datatypes and see what happens

Same version of Racket on your machine and the CI service?
