Because of the new system can download the melodic version of ros, but using the PKG is written under kinetic, download now rely on, make it, as shown in the mystery, does anyone know how to return a responsibility

Newspaper fault information navigation errors in the directory, personal feel is before you install the ros, first you compile the ros - Academy - for Beginners, and directory is in catkin_ws, because ros - Academy - for - Beginners is own navigation bag, an error may be because the compilation of ros, the ros - Academy - for - Beginners of the target file conflict. Suggest to build a directory, such as melodic_ws to store, compile new melodic,

CodePudding user response:

2 cmake is contained in the target with the same conflict

I started missing dependent on package, in the process of continuously add dependent packages, compile a few times

Could it be I'm constantly adding dependent package many times in the process of compiling

CodePudding user response:

Is likely to be repeated to compile the same rely on package, because ROS - Academy - for - Beginners itself is also need to install the other dependent on package, may conflict with ROS, so suggest you every installation of a new project, will create a new directory, don't together,
