Cross Compile For Other Platforms

Here we take an arm chip as a reference:

Main Chip	Ambarella S2L33M
Toolchain	linaro-armv7ahf-2015.11-gcc5.2
External Library	Customer’s middleware:libfbm.so

In this case, we will use the AWS KVS WebRTC sample code (kvsWebRTCClientMaster.c) to integrate with middleware into this specified platform.

1. Download the latest AWS KVS WebRTC C SDK.

    cd ~
    git clone --recursive https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c.git
    cd amazon-kinesis-video-streams-webrtc-sdk-c
   

2. Use the following command to generate and build the target executable binary and libraries.

    mkdir build && cd build
    #Export the cross compiler 
    export CC=/path/to/toolchain/bin/arm-linux-gnueabihf-gcc
    export CXX=/path/to/toolchain/bin/arm-linux-gnueabihf-g++
    #Generate Makefile
    cmake .. -DBUILD_OPENSSL=TRUE -DBUILD_OPENSSL_PLATFORM=linux-generic32 -DBUILD_LIBSRTP_HOST_PLATFORM=x86_64-unknown-linux-gnu -DBUILD_LIBSRTP_DESTINATION_PLATFORM=arm-linux-gnueabihf
    #Build code
    make -j16
   

3. Run the sample code and verify in the KVS WebRTC console or KVS WebRTC test page.

    #Use the access key ID and secret access key you created above.
    #If you don't setup the region, the defualt region will be us-west-2.
    export AWS_DEFAULT_REGION=your_desired_region
    export AWS_SECRET_ACCESS_KEY=your_secret_access_key
    export AWS_ACCESS_KEY_ID=your_access_key_id
    #Optional, to configure debug level. The level is 1 (VERBOSE) t0 7 (SLIENT).
    export AWS_KVS_LOG_LEVEL=1
   
    #Make sure your system time is up-to-date. Or you should sync it manually.
    date
   
    cd ~/amazon-kinesis-video-streams-webrtc-sdk-c/build
    #To run Amazon KVS WebRTC stream local file to the viewer side
    ./kvsWebrtcClientMaster your_desired_channel_name
