#Clion tutorial how to

I enjoy working with robots and teaching people the basics of ROS and how to get up and running. I’ve been working with ROS since my sophomore year in undergrad. Using a CMakeLists in the Top Level Workspace.For ProgramArgument put your Unreal Project, '/home/user/Documents/Unreal Projects/MyProject/MyProject.uproject'įor working directory, use the directory of your project. For the executable, select the UE4Editor which is found inside the directory “/Engine/Binaries/Linux”. When opening your Unreal Project, you will need to configure the run configuration. Set(CMAKE_CXX_COMPILER /usr/bin/clang++-6.0) Set(CMAKE_CXX_USE_RESPONSE_FILE_FOR_INCLUDES 1 CACHE BOOL '' FORCE) Set(CMAKE_CXX_USE_RESPONSE_FILE_FOR_OBJECTS 1 CACHE BOOL '' FORCE) And yes, I know it says clang+☖.0, but for some reason that is how you activate the Linux ToolChain that comes with the engine and it will automatically select the correct version of Clang.Īdd these lines to your CMakeTextLists.txt in order to compiler UE4 versions older than 4.18 # CMake Flags Also for older versions of UE4 you may need to manually add these lines in order for Cmake to compile the engine with Clang thus solve the GCC error you’re receiving. I have tested this to work on UE4.15 and UE4.22, will most likely work with all versions in between although the in Editor menus for CLion differ. But this will allow Linux users to build, test, and compile UE4 using the CLion IDE instead of only relying on Visual Studios. I am not certain if these instructions have equivalent results to those on “the building for Macs” instructions, but I have found that they work and if you need to compile the other modules, you can either follow similar steps to those above or simply compile the rest using the traditional “make” command in the terminal. If(FPaths::FileExists(TEXT('/opt/clion/bin/clion.sh')))īy following this tutorial it will create a bare bones light UE4 editor.

#Clion tutorial install

Replace “/opt/clion/bin/clion.sh” with your install location. Depending on how you installed Clion, to run CLion from the editor you may need to modify the file “Engine/Plugins/Developer/CLionSourceCodeAccess/Source/CLionSourceCodeAcess/Private/CLionSourceCodeAccessor.cpp”. Also you will see the option “Open Clion”. Lastly, in the File Menu, you should now see the option to “Refresh Clion”. Afterwards, go to your Editor Preferences, select the “Source Code” tab, and in the dropdown menu select CLion. To create the CmakeFile from the editor, go to plugins and make sure that CLion is turned on. GenerateProjectFiles.sh -project='/home/user/Documents/Unreal Projects/MyProject/MyProject.uproject' -game -engine If you want to build and compile your project, then you must, either use this command or create the CmakeFile from the editor. It will finish and you will need to stop the build once it starts scanning dependencies for FakeTarget.įinally, once the build is stopped, go back to edit configurations for UE4Editor and change the executable to UE4Editor found in /Engine/Binaries/Linux. Leave ProgramArgument empty for right now. Select FakeTarget as executable, directory as your UnrealEngine root folder. Then Edit the Configurations, you will again need to put the same settings from before. Once it stops, go back to the top drop down menu and select UE4Editor. This will stop the build and let you continue onto the next step. At this point, you can go ahead and click the stop button (near bottom left corner red square button). After it finishes, it says that it will begin scanning for dependencies for FakeTarget.

It will scan the dependencies and build the module. Next, you want to click the build button and let it finish building ShaderCompilerWorker. For right now, ignore filling in the ProgramArguments field. Configure the settings so that the executable is FakeTarget and the working directory is the root folder of your UnrealEngine. On the top dropdown menu that shows all the build Targets, first select ShaderCompilerWorker. It will then proceed to scan and index the files, once that is done, you will need to configure the build. To build UE4 on linux, you will need to first generate the CMakeFile.txt using the “./GenerateProjectFiles.sh” command with the terminal.Īfterwards, open the project (the Unreal Engine folder) with Clion. The instructions are very similar, although you will need to make some adjustments.

I’ve been experimenting with Clion and have so far gotten it to work just as well as compiling Linux on Mac with xcode. Hello, hopefully I am not too late to reply. Building on CLion UE4 for Linux Tutorial v1.1
