I guess it should be cross-compiled?
FileNotFoundError: [Errno 2] No such file or directory: 'xcodebuild'
nope, seems to expect to run on a mac
AFAICT things changed on the macos sdk since 13+
I'm afraid the solution is "build using macos < 13"
are you using a more recent macos?

Hey, I’m using MacOS 13.4 so it should work, but 
build_macos.sh
is not intended to work with 
LK_CUSTOM_WEBRTC
. When developing it is just easier to build webrtc yourself without the script. This part is not documented, I’m going to make a PR
Oh you’re using an older version of MacOS?
e
nope, latest version, but it doesn't build 😢
b
You can try to remove this line, I remember having the same issue
e
would you mind sharing some notes on how you are doing to compile 
libwebrtc
in this workflow (I'm developing inside the 
client-sdk-rust
)?
👍 1
uhhh will give it a try!
b
Yes, I’ll do that inside the webrtc-sys readme

e
awesome! thank you!
I'm currently doing everything on linux because I managed to get it building there
btw: is there any resource you recommend to use to learn these libwebrtc api's / architecture / inner workings?
b
There is this doc but unfortunately, I don’t think there is a detailed documentation, I think the best way to understand things is to read the code.

e
awesome, thank you theo!
🙏 1
out of curiosity: for how long have you been working with this codebase? you kick butt!

well... managed to compile libwebrtc on mac, but then it fails to link to the 
wgpu_room
example
linker error I'm getting when attempting to compile `wgpu_room`:
