Build for iOS failed: the following arguments are required: --sio_root

[resignedScientist]

When I run:
python build.py

it fails with the message:
"build.py: error: the following arguments are required: --sio_root"

What is this argument and what do I write after the argument?

Running on MacOS Ventura using the latest main branch

[jianjunz]

build.py --help displays description for arguments. sio_root is the path for Socket.IO cpp.

Ok now I have built Socket.IO using this: https://github.com/kim-company/socket.io-client-cpp-ios-static

when I now run
python build.py --sio_root […]

it takes a while but then fails with:
../../talk/owt/sdk/conference/conferencesocketsignalingchannel.h:16:10: fatal error: 'sio_client.h' file not found #include "sio_client.h" ^~~~~~~~~~~~~~ 1 error generated.

I am on the main branch btw. I also tried using the v5.0 tag, but that fails with another error:
File "/Users/laudien/Projekte/WebRTC/src/scripts/build.py", line 150 print 'Start running unit tests.' ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

Do I have to use a specific python version for this? I use Python version 3.11.1

Or do I have to run gclient sync again when switching commits?

cloning socket.io-client-cpp-ios-static repository comes with a /static_builds/commit_b1216ee428dd7d1e72368da9b12aa43bfc487c93/ folder with 2 files in it

• arm64_libsioclient.a
• arm64_libsioclient_tls.a

while passing path to python build.py --sio_root <path> which <path> should I provide

I provided the path till arm64_libsioclient.a file but was getting same error of 'sio_client.h' not found and 'sio_message.h' not found

python src/scripts/build.py --sio_root ./socket.io-client-cpp-ios-static/static_builds/commit_b1216ee428dd7d1e72368da9b12aa43bfc487c93/arm64_libsioclient

I followed the instructions from https://github.com/socketio/socket.io-client-cpp/blob/master/INSTALL.md after which I figured out that running make install adds all the required headers(.h) files and .a files which are

• sio_client.h
• sio_message.h
• sio_socket.h
• libsioclient.a
• libsioclient_tls.a

inside /usr/local/ directory by default at following locations

/usr/local/include/sio_client.h
/usr/local/include/sio_message.h
/usr/local/include/sio_socket.h
/usr/local/lib/libsioclient.a
/usr/local/lib/libsioclient_tls.a

Thus, I used command python ./scripts/build.py --sio_root /usr/local/ and I got rid of this error atleast.

But now, I am stuck with another error which says

python ./scripts/build.py --sio_root /usr/local/

I could finally get rid of this error following #62 (comment) in #62 and had to use the command python ./scripts/build.py --sio_root /usr/local/ --skip_tests to avoid errors in test files stop me.

I could finally see the "Done" message after running this (had to once delete the entire /out/ directory before being able to successfully run this. You could also consider running gclient sync once as well before trying this.)

Finally it generated three folders in out directory.

I believe this completes the three steps needed for iOS build steps as mentioned by this https://github.com/open-webrtc-toolkit/owt-client-native#ios

I would want to know the next steps after this, which I am still struggling to find out!
