Cannot build rust mediasoup

Deployment & Scalability
1

While trying to build a project using rust mediasoup, I get:

ERROR: Subproject exists but has no meson.build file

I cannot seem to get the cargo build command to run. I’ve tried deleting the entire target folder and retrying, but it fails 100% of the time.

Here is my meson-log.txt file:

Please advise

Please use search on the forum next time.

I don’t know where to find those directories

I just created a fresh project, added mediasoup = "0.9.0" as dependency and it worked fine on Ubuntu 21.04.
Deleting target directory would have helped for sure.

What OS are you on? Also make sure network doesn’t block access to downloading some of the dependencies (like from GitHub).

I’m on Ubuntu 20.04. It seems that the directories that were causing problems were in my local ~/.cargo cache of mediasoup, not in the target directory of the project itself. I resolved it by deleting mediasoup from the cargo cache.

Interesting and weird. Either way, the other topic linked is still relevant and this issue should generally go away once fixed upstream.
