工程师您好,自己新建的包,update,upgrade之前编译都是好的,之后再编译时都出错,请看下是什么原因。
1当前环境:
apt update
apt upgrade
tros 1.1.6
2编译时的打印信息:
root@ubuntu:~/dev_ws# colcon build --packages-select cpp_dnn_demo
Starting >>> cpp_dnn_demo
-– stderr: cpp_dnn_demo
CMake Error at /opt/tros/share/fastrtps/cmake/fastrtps-targets.cmake:79 (message):
The imported target “fastrtps” references the file
“/opt/tros/lib/libfastrtps.so.2.1.3”
but this file does not exist. Possible reasons include:
* The file was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and contained
“/opt/tros/share/fastrtps/cmake/fastrtps-targets.cmake”
but not all the files it references.
