Clion compiling catkin_ WS (short for ROS workspace package) loads cmakelists Txt problems

The background is that I was in ROS working space 3308_ws Folder ROS My bag :

[email protected]:~/3308_ws$ catkin_make

It can be compiled , stay Clion IDE Loaded inside CMakeLists.txt Files can be compiled . A few days later, there was no link ROS Original source library ： /opt/ros/indigo/... The file of . Make a mess , If the compilation fails, I thought it was python Version of the problem , But it's not , Finally Baidu solved the problem .

problem ：Clion IDE Loaded inside CMakeLists.txt File error ：

find_package(catkin) failed.  catkin was neither found in the workspace nor   in the CMAKE_PREFIX_PATH.  One reason may be that no ROS setup.sh was sourced before.

resolvent ：

1. Open the terminal

2. If not running catkin_make Generate files , Remember now src The location where the folder is located runs catkin_make

3. Open the... Of the workspace devel Folder

4. Run the command ( It's very important )

   source setup.bash

    

5. open clion.sh Folder in which （ Just search ）, Run at terminal

   ./clion.sh

   Then right click cmakelist.txt file , Just reload

6. Start at the terminal CLion,CLion It should be through setup.bash The local environment variable set by the file starts , Therefore, in the error report ：no ROS setup.sh was sourced before The problem is solved ！（ The red part doesn't understand how to operate )

         After execution source After the instruction ： I run directly on the workspace clion.sh Instructions

[email protected]:~/3308_ws$ ../Downloads/clion-2020.2/bin/clion.sh 

        And yes. catkin_make Instruction generated package compilation file build and clion Compile generated cmake-build-debug It's different , You don't need to set these two files . stay setting->Build->CMake->CMake options/Build directory These two can be set

Two .Clion Opening an external project failed to compile the problem

Or in :CMakeLists.txt Right click mouse , choice Reload CMake Project Reload CMakeLists.txt file
