| CLion is a proprietary IDE for C++.
| | Moved to https://develop.kde.org/docs/getting-started/building/ide/clion/ |
| | |
| == Install CLion ==
| |
| | |
| On Arch Linux install the [https://aur.archlinux.org/packages/clion clion].
| |
| | |
| == Setup ==
| |
| | |
| Open a new project in CLion. Locate it to the folder with CMakeLists.txt. It will ask how do you want to open the project. Select CMake project.
| |
| | |
| [[File:Clion open as cmake project.png|border|300px|open as cmake project]]
| |
| | |
| In CMake configuration, choose Debug build. In the Generator, set "Let Cmake decide". In the Build directory, insert the build directory path, for example, "/home/username/kde/build/dolphin".
| |
| | |
| [[File:Clion build configuration.png|border|700px|build configuration]]
| |
| | |
| Under CMake options, we must set some important variables such as CMAKE_PREFIX_PATH. If the prefix was in "/home/username/kde", then the CMake options line would look like:
| |
| | |
| {{Input|1=<nowiki>
| |
| -DCMAKE_PREFIX_PATH=/home/username/kde/usr | |
| -DCMAKE_MODULE_PATH=/home/username/kde/usr/lib64/cmake:/home/username/kde/usr/lib/cmake
| |
| -DQT_PLUGIN_PATH=/home/username/kde/usr/lib64/plugins:/home/username/kde/usr/lib/plugins
| |
| -DXDG_DATA_DIRS=/home/username/kde/usr/share
| |
| </nowiki>}}
| |
| | |
| Press OK.
| |
| | |
| In the run/debug target (in the upper right corner of main window), select "dolphin".
| |
| | |
| [[File:Clion select run debug configuration.png|border|300px|select run debug configuration]]
| |
| | |
| Expand it and choose Edit.
| |
| | |
| [[File:Clion go to run debug configuration edit.png|border|300px|go to run debug configuration edit]]
| |
| | |
| The Run/Debug Configurations window will appear. In the Environment variables field click edit button.
| |
| | |
| [[File:Clion run debug configuration.png|border|500px|run debug configuration]]
| |
| | |
| Add variables, that you can find in build directory, for example, in "/home/username/kde/build/dolphin/prefix.sh".
| |
| | |
| [[File:Clion run debug configuration add variables.png|border|500px|run debug configuration add variables]]
| |
| | |
| Note: if you want to modify debugging output messages, you can add corresponding variables here. See [[Guidelines and HOWTOs/Debugging/Using Error Messages#Controlling_Messages]].
| |
| | |
| In the Toolchains you can use bundled cmake and gdb. In Arch Linux their versions are very recent and not yet supported by CLion. They can be installed with [https://aur.archlinux.org/packages/clion-cmake clion-cmake] and [https://aur.archlinux.org/packages/clion-gdb clion-gdb].

| == Tips and Tricks ==
| |
| | |
| === Out of tree breakpoints ===
| |
| | |
| You may want the debugger to stop on a specific breakpoint, that is located out of project tree. For example, you run and debug dolphin project: select several files, with context menu you add them to archive. And you want the debugger to stop on some function of Ark's code.
| |
| | |
| For this, you just open the corresponding file, and put a breakpoint there. No even need to map sources, like you need in Qt Creator.
