![]() However, Eclipse WILL NOT BUILD if any in-source build files exist. If this build option isn’t specified, then CMake will do an “in-source build” where build files will be strewn about with the source code. These build files are then used to compile the program. This is where the build files will be put after calling the cmake command. CMake has an option to specify a “build” location with the “-build” or “-B” options. There is one extremely important note here. Buildingįrom here, write some code and a CMakeLists.txt file and you will be ready to build! Building is easy with Eclipse, just press the hammer icon to build or go to the Project tab for more build options. Choose a name and un-check the “Use default location” box so that you can point it at the directory you cloned from Github. This will not create a starting template to work from and so is good for either a clean slate or creating an Eclipse project for existing code. From here choose Empty or Existing CMake Project. With the project directory cloned from Github, start Eclipse and choose File -> New -> C/C++ Project. I like doing it this way so that I don’t have to deal with creating a README.md file myself, which I would need to do if I create a git repository locally and then push it to an upstream location on Github. My preferred method for starting from scratch is to create a new repository on Github, and then clone that repository to my local machine. You may need to close and re-open any CMake files, but now you will have proper syntax highlighting for you CMake files! Creating the Project Search for this extension, install it, and then restart Eclipse. There is an extension from the Eclipse Marketplace (Help -> Eclipse Marketplace) called cmake-editor that can help with this. Honestly, it is pretty miserable to work with them like this. You can open them in the editor and modify them, but there is no syntax highlighting. Specifically, Eclipse doesn’t have support for CMakeLists.txt files out of the box. Marketplace Packagesįirst thing’s first, we need to set up Eclipse to play nicely with CMake. Here, I’ll document my process for setting up a CMake project in Eclipse and getting started with development of a new project. This is great, but at the start of every project I spend an absurd amount of time getting an Eclipse project set up. I, on the other hand, prefer to use CMake and Makefiles to prevent being locked down to one IDE for building. ![]() However, each IDE seems to have its own custom build system. Integrated Development Environments (IDEs) are fantastic tools to speed up the software development process.
