Seen from the above should have correct reference roscpp, and add_executable () also behind the various reference function order no problem, very puzzling problem in where? Seek help from a great god!
CodePudding user response:
I compiled in ROS helloworld also encounter the same problem, as long as the reference ROS function will prompt "undefined reference", when the annotation to the main function of ROS function to compile, there is no mistake, CMakeLists. TXT, package. The XML, the source environment variable, check n times, with strives for the great god help!CodePudding user response:
Find the solution to the problem, to build the workspace and package, perfect solution!
