If you want to try out building Mixxx with CMake yourself, check the instructions in our wiki. We plan to drop SCons and fully migrate over to CMake in 2.4.
Cmake build driver#
Most of our core developers already switched over to CMake as their daily driver when working on Mixxx, but since it hasn't been as widely tested as we'd like, we label the support as "experimental" for the 2.3 release and stick with SCons for the release builds.
Cmake build mac#
Note that there are still some issues with building Mixxx on macOS with CMake, so if you own a Mac we'd appreciate if you help us out.Īpart from that, it's already working quite well.
Arguably, CMake is vastly more popular than SCons, so we hope that more people be able to build and contribute to Mixxx. With CMake, we added support for ccache (and clcache on Windows), which makes development significantly faster. This solution took a lots of disk space and also had occasional issues with failed builds. 
To avoid this, we had a custom caching solution in SCons, which cached the compilation units based on the git branch you're working on. Unnecessary recompilation is annoying and a waste of time. Dependencies between the targets are expressed in the buildsystem to determine the build order and the rules for regeneration in response to change. Each target corresponds to an executable or library, or is a custom target containing custom commands. There is even a standalone GUI that you can try. A CMake-based buildsystem is organized as a set of high-level logical targets.
Cmake build free#
Feel free to have several build directories, like build and build-xcode. In this step CMake will generate native build tool files using information from CMakeLists.txt and variables from CMakeCache.txt. IDEs such as KDevelop, Visual Studio or CLion have support for CMake built-in. You should pick a tool on your first CMake call in a directory, just like the compiler.
If you prefer a graphical "build" button over compiling Mixxx on the command line, this is now possible:. Cmake build code#
We managed to reduce the line count from approximately 8000 lines of Python code down to a 2300 line CMakeLists.txt file plus modules.Īll in all we reduced the line count by almost 3000 lines.
The code is more maintainable and requires fewer platform-specific hacks.Īlso, less code is necessary. Most linux distributions contain CMake as a package on Windows and. Hence, we added support for the CMake build system ( or rather: build system generator), which many C++ developers are already be familiar with. CMake allows building wxWidgets on various platforms with your preferred build system. The section marked as ADVANCED need not be read by someone only trying to compile SALOME. This makes our build scripts hard to maintain on all platforms and has lead to problems in the past. In recent years it has become a de-facto standard for C and C++ applications, so the time has come for a lightweight introductory article. CMake is a collection of open-source and cross-platform tools used to build and distribute software. A look at one of the most popular build systems for C and C++. Unfortunately, it requires lots of boilerplate code to accomplish simple tasks. Introduction to modern CMake for beginners. Since it's based on the Python programming language, it's quite flexible and can be used to customize every build step. Mixxx has used SCons as its build system for more than 13 years. CMake support also provides robust unit and. This will probably be more interesting for people who are either compiling Mixxx themselves or going hack on its code base than for regular users, but it will make the build process more straightforward in the future. CMake will allow for building netCDF on a wider range of platforms, include Microsoft Windows with Visual Studio.
