State #DF4 - pkg-config required by Ocaml package

Challenges
1

I’m stuck on Stage #DF4 - Compression Headers.

To compress the content of the HTTP body, I installed the OCaml dependency ezgzip 0.2.3 (latest) · OCaml Package. According to the logs, this package requires pkg-config to be present on the build machine.

I’ve not found a suitable alternative package. I could try to execute a sub process to call gzip (assuming it would be present) to compress the string, but that feels like a workaround.

Thanks for you help.

Here are my logs:

Hey @rubenbakker, looks like you’ve completed the HTTP server challenge without pkg-config. :tada:

Let me know if you’d still like pkg-config to be installed in the OCaml environment.

Hi @andy1li. I implemented a workaround by using gzip. If you’d be able to add pkg-config, I’d love to replace the workaround with a proper solution. Thanks!
