You can see the results of this process in the Build tool window. Otherwise you can open the compile_commands.json file directly and select Open as Project:Īfter that CLion will automatically create a project from this file and import all its contents. To do so, simply open the directory that contains the file in CLion. Now that you have a compile_commands.json file, you can use it to create a CLion project. ![]() Note: If you accidentally deleted the compile_commands.json file, it can be regenerated by invoking Meson reconfiguration ( meson -reconfigure ). In this command, -t compdb instructs Ninja to generate compile_commands.json instead of building the project and -x tells Ninja to expand response files ( rspfile) during database generation (available since version 1.9), while c_COMPILER and cpp_COMPILER are the names of Ninja rules generated by Meson. Ninja -t compdb -x c_COMPILER cpp_COMPILER > compile_commands.json. If, for some reason, Meson doesn’t generate compile_commands.json, you can use Ninja. Compilation database generation is provided by Ninja, rather than by Meson itself. Meson will automatically place compile_commands.json inside the generated build directory. You don’t need to perform any additional steps to generate the compilation database from a Meson project. Other backends (Visual Studio and Xcode ) do not support compilation database generation. Note: compile_commands.json can only be generated if Ninja is used as the backend build system. ![]() Many build systems offer the ability to generate compilation database files ( compile_commands.json), and Meson is one of them. CLion has natively supported compilation database projects since version 2018.2. However, it has gained popularity in general C/C++ tools as a simple yet powerful way to describe project files. It was originally introduced as a part of Clang tooling. What are compilation databasesĬompilation database is a simple JSON file format for associating compilation flags with files in a project. However, as always there are some important details to discuss. Generate a compile_commands.json file from your project. ![]() To open a Meson project in CLion, you just need to perform two simple steps: Steps described here can be reproduced on Windows (including all available toolchains), Linux, and macOS. Note: In this post we will use the DPDK project as an example. However, in this blog post we’ll describe how you can use compilation databases to set up your Meson project in CLion in just a couple of simple steps. CLion currently does not natively support Meson projects. Recently Meson has started to gain popularity among C++ developers. It converts build scripts written in a Python-like language into one of the backend build systems: Ninja (the default and recommended one), Visual Studio, or Xcode. Meson is a relatively new build system that strives to be fast yet simple to use. For this we will use compilation database support in CLion. Today we are going to show you how you can already use Meson-based projects in CLion. Meson support works on all platforms and for all local and remote toolchains, including WSL and Docker.ĭuring the recent Q&A session on Reddit, we got a surprising number of questions about our plans for Meson support. It has all the bases covered and it will be enough for most of your coding needs and project requirements.Since CLion 2023.3, you can natively open, build, and run/debug Meson projects. ![]() If you are a C and C++ programmer, this is one tool that is worth checking out and integrating into your daily workflow. A C++ coder's best friendĪll in all, CLion has one sole and laser-focused use case and it does it impressively well. If you do encounter major issues, there's a built-in debugger to help you investigate, fix, and redeploy them easily and as swiftly as possible. These can be addressed with a click of a button and CLion will handle the rest. It will immediately inform you when it detects any potential coding issues as you're typing. This IDE lets you focus on your work while it does code analysis on the fly. When it's time to review and inspect your code, documentation is quick and easy, allowing you to learn more about C++ programming while making the necessary changes that are needed. Whenever you rename symbols, change functions, or set new parameters, it ensures that everything is propagated throughout your code regardless of what automated refactoring method you use. The program also offers various code generation options, such as overriding and implementing functions using simple shortcuts. ![]()
