这个错误提示表明在运行./hmi_bridge时,系统无法找到名为libfastrtps.so.2.8的共享库文件。解决这个问题的方法是确保该库文件已经正确安装,并且已经被正确链接。你可以尝试以下几个步骤来解决这个问题:
1. 确认libfastrtps.so.2.8是否已经正确安装。你可以使用以下命令来查找该文件:
```shell
find / -name libfastrtps.so.2.8
```
如果该文件已经安装,该命令会返回该文件的路径。
2. 如果该文件已经安装,但是系统仍然无法找到该文件,你可以将该文件所在的目录添加到LD_LIBRARY_PATH环境变量中。你可以使用以下命令来添加该目录:
```shell
export LD_LIBRARY_PATH=/path/to/libfastrtps:$LD_LIBRARY_PATH
```
其中,/path/to/libfastrtps是libfastrtps.so.2.8所在的目录。
3. 如果以上两个步骤都无法解决问题,你可以尝试重新安装libfastrtps.so.2.8库文件,并确保正确链接该库文件。

USART_HMI\USART_HMI.hex: Error: Q0122E: Could not open file 'USART_HMI\USART_HMI.axf': No such file or directory
As an AI language model, I cannot access your file system. However, this error message suggests that the linker is unable to find the output file 'USART_HMI.axf', which is required for generating the final executable file 'USART_HMI.hex'.
You may need to check if you have specified the correct path for the output file, or if the file has been generated successfully during the build process. It is also possible that there may be some issues with the toolchain or the project configuration.
CMake Error at /home/kali/car_test/build_isolated/hmi_msgs/cmake/hmi_msgs-genmsg.cmake:3 (message): Could not find messages which '/home/kali/car_test/src/simulation/shaver/msgs/hmi_msgs/msg/Fixed_point.msg' depends on. Did you forget to specify generate_messages(DEPENDENCIES ...)?
这个错误是由于在生成 `Fixed_point.msg` 消息时,没有指定该消息依赖的其他消息,导致找不到依赖的消息而报错。可以在 `CMakeLists.txt` 文件中的 `generate_messages` 函数中加入 `DEPENDENCIES` 参数,指定该消息依赖的其他消息,示例代码如下:
```
add_message_files(
FILES
Fixed_point.msg
)
generate_messages(
DEPENDENCIES
std_msgs
)
```
其中,`std_msgs` 为 `Fixed_point.msg` 消息所依赖的消息包。
