I've downloaded the livekit python setup files into ~/opt/src but not sure what to do from here as it doesn't have the configure file.

I also tried to install without wheel but running into issue with

OSError: /lib64/libstdc++.so.6: version CXXABI_1.3.8' not found (required by /home/opal_username/opt/src/livekit-0.12.1/livekit/rtc/resources/liblivekit_ffi.so)

what would be easiest way to install this python module on Opalstack?

  • sean replied to this.

    009co I've tried various approaches and can't find a solution for the "cannot import name 'get_platform' from 'wheel.bdist_wheel'" error.

    What commands did you run that resulted in the "/lib64/libstdc++.so.6" error?

      009co Actually, I've just found a workaround by editing setup.py in the livekit Python sources. Here are the commands to install from source:

      # first activate your virtualenv, then:
source scl_source enable devtoolset-11
cd ~/opt/src
git clone https://github.com/livekit/python-sdks.git
cd python-sdks/livekit-rtc
sed -iE 's/from wheel.bdist_wheel import get_platform/from wheel._bdist_wheel import get_platform/' setup.py
pip install .

      Please give that a try 🙂

        Thank you! i was fiddling with variations of using setup.py : ) but yours does seem to install livekit.

        It does seem to be installed. eg this works

        import livekit (good it works)

        but locally i can the following but it is not working in this remote env we just set up.

        from livekit import rtc (it doesn't work)
        from livekit.rtc import Room (it doesn't work)

        Not sure what to make of this. Any ideas?

        • nick replied to this.

          009co If this file does not exist in this path /home/opalstack_username/apps/appname/env/lib/python3.12/site-packages/livekit/rtc/resources/liblivekit_ffi.so (maybe it's in ~/opt/src?), then try locating it and including the path to it via LD_LIBRARY_PATH, e.g.:

          export LD_LIBRARY_PATH=/home/opalstack_username/path/to/library/:$LD_LIBRARY_PATH

            Actually the file "liblivekit_ffi.so" referenced in the error isn't anywhere to be found not even in github repo at the path "livekit/rtc/resources/liblivekit_ffi.so" the resources dir is empty.

            • nick replied to this.

              009co You can build the libraries using cargo. I redid the whole process as below but got stuck and haven't figured out a work around just yet, but maybe it will be helpful for you:

              source scl_source enable devtoolset-11 llvm-toolset-7
#Need at least Python 3.9+
python3.12 -m venv ~/myenv
source ~/myenv/bin/activate
mkdir -p ~/opt/src
cd ~/opt/src
git clone https://github.com/livekit/python-sdks.git
cd python-sdks
git submodule update --init --recursive
cd livekit-rtc/rust-sdks/livekit-ffi
export LIBCLANG_PATH=/opt/rh/llvm-toolset-7/root/usr/lib64
cargo build --release
cd ~/opt/src/python-sdks/livekit-rtc
sed -iE 's/from wheel.bdist_wheel import get_platform/from wheel._bdist_wheel import get_platform/' setup.py
pip install .
export LD_LIBRARY_PATH=$HOME/opt/src/python-sdks/livekit-rtc/rust-sdks/target/release:$LD_LIBRARY_PATH

#Create symlink to work around "No such file or directory"
ln -sf $HOME/opt/src/python-sdks/livekit-rtc/rust-sdks/target/release/liblivekit_ffi.so $HOME/opt/src/python-sdks/livekit-rtc/livekit/rtc/resources/liblivekit_ffi.so

#Test
python -c "import livekit; from livekit import rtc"

                Thanks, that helped advance the attempt to install livekit module on Opalstack though with tons of warnings and ultimately not passing the test.

                What looks positive

                However the test

                python -c "import livekit; from livekit import rtc"

                resulted in an error

                ChatGPT and friends suggest the build is not matching environment?

                • sean replied to this.

                  009co we've been trying to solve this for the past 24 hours but we're unable to get it working on our servers because the operating system is too old.

                  We should have new servers with a new operating system available by the end of the 3rd quarter (in about 6-7 weeks). I've tested livekit on the new OS and confirm that it will work there. We'll make an announcement here in our forum when the new servers are ready.

                      sean Hey Sean, great thanks for the quick, detailed, actionable responses, and the update!
