Before starting with CLion, check this Quick Start Guide.
Configure and use different toolchains for different projects in CLion, or even inside one project for different configurations.
You can change CMake executable, Make, C and C++ compilers and debugger. Note that you can use either bundled or custom version of CMake and debugger executable.
Use Remote toolchains for building, running and debugging on a remote host.
Windows Subsystem for Linux
On Windows use WSL toolchain. Compile, run, and debug Linux binaries while working on Windows. Test targets under Valgrind Memcheck to detect possible errors and leaks.
Microsoft Visual C++ compiler
CLion supports and auto-detects Microsoft Visual C++ compiler from Visual Studio 2013, 2015 and 2017. MSVC is used along with the NMake generator in CLion.
Debugger is not supported in this case.
All work in CLion is done within the context of a project, which serve as the basis for coding assistance, bulk refactoring, coding style consistency, and other smart features.
Start a new project
To start a completely new project, use
File | New Project... to generate the sample project. For C and C++ CLion will create a CMake project and pre-fill root CMakeLists.txt with the necessary information.
Open an existing project
To start with an existing project in CLion, select one of the following options:
- For CMake project: locate the root CMakeLists.txt file, CMakeCache.txt file or CMake generation directory (the last two options work only for Makefiles generator).
- For Gradle C++: open the build.gradle file from the project sources.
- For compilation database: use the compile_commands.json file (see this list of ways to get a compilation database for your project).
- For other project models: open a single file or a folder with C/C++ sources in CLion, mind the code insight will be limited in this case.
- Alternatively, import a C/C++ project from an existing source, and CLion will create CMakeLists.txt for you.
Add new files
New files can be added to the project by using the New menu. In the Project tree view, press Alt+Insert or select New in the context menu.
- Click C++ Class to generate a .cpp file source file with a header and a class stub:
- Click C/C++ Source File to generate a simple source file, optionally with an associated header.
- Click C/C++ Header File to generate a simple header file.
