hi @fengmao31 , you can try the following steps

cd CyberRT
source install/setup.bash
cd build
source setup.bash
./cyber/examples/cyber_example_talker

[fengmao31]

yes. if you want to run the application, you also need source install/setup.bash, setup.bash.
I propare to make a new setup.bash to deployment.

if you third_party install /usr/local, you not need source install/setup.bash

我也遇到同样的问题，应该是你的~/.bashrc里将ros的/opt/ros/foxy/setup.bash依赖添加到环境变量里了，即使你执行cyber的setup.bash，启动cyber示例仍然是会调用到/opt/ros/foxy的libfastcdr.so，可以使用ldd libcyber.so查看具体的连接库版本，要解决这个问题先注释掉加载ros的setup.bash命令，然后仅加载cyber的setup.bash，应该可以运行cyber示例了，希望对你有帮助
