Installation procedures
CMake can generate both XCode and Visual Studio project, and it is supported by CLion natively. Depending on the complexity of your application, you will likely need OS-specific branches in your CMake and C code, but CMake has plenty of different ways to assist with that. CLion is a cross-platform C/C IDE for Linux, OS X, and Windows. CLion includes such features as a smart editor, code generation, code quality assurance, automated refactorings, on-the-fly code analysis, project manager, integrated version control systems and debugger. Mar 08, 2021 Toolbox is a control panel that allows you to manage all JetBrains developer tools, including CLion, as well as your projects, from a single point of access. It enables you to maintain different versions of CLion, install updates and roll them back if needed. Tightly integrated with the Cocoa and Cocoa Touch frameworks, Xcode is an incredibly productive environment for building amazing apps for Mac, iPhone, and iPad. What companies use CLion?
Before you start the CLion installation on macOS, make sure your machine meets the hardware requirements, and the version of your macOS is 10.9.4+.
You can always have multiple instances of CLion installed on the same OS, including both release and EAP builds.
- Download the latest release or EAP version of CLion for macOS (earlier versions are available on the Previous CLion Releases page).
- Open the downloaded CLion-*.dmg package and drag CLion to the Applications folder.
- Mod_proxy tomcat. Open the Applications folder and launch the CLion installer.
- If the security warning appears, agree to open the application:
- When you install CLion manually, the update checking is performed automatically by default (every time the IDE is ready to update, you will see a message in the status bar ). To configure the update process, go to Preferences | Appearance and Behaviour | System Settings | Updates and select the update channel:Click Check now to perform the checking right away. In case there are available updates according to the chosen channel, you will see a dialog like the following:
Toolbox is a control panel that allows you to manage all JetBrains developer tools, including CLion, as well as your projects, from a single point of access. It enables you to maintain different versions of CLion, install updates and roll them back if needed. Toolbox remembers your JetBrains Account and uses it to automatically log in when you install and register new tools.
- Download Toolbox and launch the setup file.
- When the installation is complete, accept the JetBrains privacy policy and sign in to your JetBrains Account.
- Now you can choose which version of CLion to install:
- Toolbox shows the list of the installed versions:
- In the Settings dialog, configure the way of updating CLion:Note that in case of using Toolbox, the update process cannot be configured from within the IDE. The Preferences | Appearance and Behaviour | System Settings | Updates dialog shows the following message:
Alternatively, you can install CLion via the Homebrew package manager :
brew cask install clion
. However, this option is unofficial, as the CLion team is not involved in its maintenance or support.After the installation or upgrade, you will be prompted to import, inherit, or create new settings for the IDE.
Required tools
CLion needs to be provided with C and C++ compilers and the make utility. These tools may be pre-installed on your system: check it in Preferences | Build, Execution, Deployment | Toolchains- the compiler and make detection should perform successfully.
If your system does not have working installations of compilers and make, the simplest solution is to install Xcode command line developer tools.
- Run the following command:Microsoft Windows 10 1607 “Anniversary Update” or later version; 2.8 Ghz 6th Generation Intel® Core™ i3 Processor with 2 CPU Cores or 2.8 Ghz 1st Generation AMD® Ryzen™ 3 Processor with 2 CPU Cores (Recommended 3.5 Ghz 8th Generation Intel® Core™ i5 Processor with 4 CPU Cores or better or 3.5 Ghz 2nd Generation AMD® Ryzen™ 5 Processor with 4 CPU Cores or better). Camtasia studio 8 key. Camtasia is the best all-in-one screen recorder and video editor. Record your screen, add video effects, transitions and more. Software available on Windows and Mac. Try for free today! Camtasia 2020 makes it simple to record and create professional-looking videos on Windows and Mac.
- When prompted to install command line developer tools, click the Install button:You can also choose to install the full package of Xcode, though it is not necessary for CLion.
With Xcode command line tools, you get the Clang compiler installed by default. To check the compiler presence and its version, run
clang --version
.Command line tools may not update automatically along with the system or Xcode update. This may cause error messages like invalid active developer path during project loading in CLion. To fix this, run the same
xcode-select --install
command, and the tools will be updated accordingly.![Xcode Xcode](/uploads/1/3/7/8/137884988/954415171.png)
As an alternative, you can separately install compilers and make, and then provide the paths in Preferences | Build, Execution, Deployment | Toolchains.
Note that you can use multiple compilers for the needs of your project, see Switching Compilers.
Configure toolchains
Now you need to configure the toolchain to work with, which means choosing the CMake executable, the make and C/C++ compilers location, and the debugger. Navigate to Preferences | Build, Execution, Deployment | Toolchains and edit the default toolchain, or click to add a new one.
CMake, make, and compilers
In the CMake field, specify the CMake binary that you want to use. You may stick to the bundled CMake, or use your custom CMake executable (see the minimum supported version in Software requirements ).
The chosen CMake attempts to detect the compilers and make considering the packages installed on your system. If the detection succeeds, the fields Make, C Compiler, and C++ Compiler are filled automatically:
The detection of compilers and make fails if CMake cannot locate the appropriate tools (this may happen, for instance, if you installed them separately without the Xcode developer tools). In this case, you need to provide the actual paths manually.

Debugger
CLion for macOS comes with the bundled LLDB v 10.0.1 (the default debugger) and GDB v 10.1. You can also switch to a custom GDB (supported versions are 7.8.x-8.1.x). Select the debugger in Preferences | Build, Execution, Deployment | Toolchains:
Issues are possible when working with both bundled or custom GDB on macOS. To improve the behavior, enable the cidr.debugger.gdb.workaround.macOS.startupWithShell option in Registry (select Help | Find Action from the main menu and type Registry ):
Note that enabling this option is not equivalent to setting
set startup-with-shell off
in your .gdbinit script.A combination of GDB and Clang implies certain limitations to debugging your projects on macOS. See STL renderers for GDB on macOS for details and a workaround.
Further steps
Now that you have CLion installed and configured, you may find the following articles useful for further steps of the development:

Open a project
To open an existing CMake project in CLion, do one of the following:
- Select File | Open and locate the project directory. This directory should contain a CMakeLists.txt file.
- Select File | Open and point CLion to the top-level CMakeLists.txt file, then choose Open as Project.
- Select File | Open and locate the CMakeCache.txt file, then choose Open as Project.
Create a new project
- If no project is currently opened in CLion, click New Project on the Welcome screen. Otherwise, select File | New Project on the main menu.
- In the New Project dialog that opens, select the target type of your project (executable or library), and the language to be used (pure C or C++). CLion will generate the top-level CMakeLists.txt file based on the provided settings.
As an example, let's create a simple shared library assuming the C++14 standard.
- Click New Project from the Welcome screen or the File menu.
- In the left pane, choose C++ Library.
- In the right pane, set the location and the name of your project. You can type the path in the text field or click to browse for the desired folder.
- Click the Language standard control and select the standard from the drop down list (C++14 in our example).
- Use the Library type control to select the library type (shared in our example).
- Click Create to create a project and generate the corresponding CMakeLists.txt file:
You can set up a CMake profile to be used for all new projects by default (File | New Projects Settings | Settings for New Projects | Build, Execution, Deployment | CMake ).

Create a CMake project from sources
Clion Code Block
To work with non-CMake sources in CLion, you can convert them into a CMake project structure.
- On the main menu, choose File | Open and select the project root folder.
- Open a source file in the editor.
- If there is no top-level CMakeLists.txt file, CLion will suggest creating it:The Create CMakeLists.txt action appears only when there is no CMakeLists.txt under the project root, disregarding the subfolders' CMakeLists.txt files.If there is a CMakeLists.txt file under the root, the only available action will be Select CMakeLists.txt.
- In the Create CMakeLists.txt dialog, specify the following:
- Select project files- select the files to be imported as project files. Use the subdirectories checkboxes to import their entire contents or clear the checkboxes to import the contents selectively.
- User Include Directories- select the directories to be included in the project and specified in the CMake include_directories command. CLion includes a directory automatically when it contains at least one header file, if it is named include, or when it has subdirectories that contain header files only.Note that directories not selected in the Select Project Files pane are not presented in the User Include Directories list - select them first, and then the available include directories will appear in the list. Couple pencil sketch.
Work with a monorepo
Clion Open Xcode Project
Monorepos are repositories that combine multiple projects, usually without a top-level CMake script. Instructions below describe how to work with a monorepo in CLion using LLVM Project as an example.

- Call File | Open and point CLion to CMakeLists.txt in the required subdirectory. For the case of LLVM, select llvm-project/llvm/CMakeLists.txt.In the dialog that opens, click Open as Project.
- Go to Settings/Preferences | Build, Execution, Deployment | CMake and use the CMake options field to add the sub-projects that you want to build additionally.For example, to add clang and clang-tools-extra, specify
-DLLVM_ENABLE_PROJECTS=“clang;clang-tools-extra”
:Project reload should perform successfully at this point. - To be able to view the entire repository in the Project tree, change the project root: call Tools | CMake | Change Project Root from the main menu and select the top-level repository folder, llvm-project.
- We also recommend that you build the project. This way, resolve will work on the entire codebase, including the parts generated at build time.
