&kdesrc-build; features include: You can pretend to do the operations. If you pass --pretend or -p on the command line, the script will give a verbose description of the commands it is about to execute, without actually executing it. However if you've never run &kdesrc-build;, you would want to run the kdesrc-build --metadata-only command first in order for --pretend to work. For an even more verbose description of what &kdesrc-build; is doing, try using the --debug option. &kdesrc-build; allows you to checkout modules quickly. If the module you are checking out has already been checked out previously, then &kdesrc-build; will download only commits that are not yet on your computer. There is generally no need for any special preparation to perform the initial checkout of a Git module, as the entire Git repository must be downloaded anyways, so it is easy for the server to determine what to send. This is faster for you, and helps to ease the load on the kde.org anonymous &git; servers. Another speedup is provided by starting the build process for a module as soon as the source code for that module has been downloaded. (Available since version 1.6) Excellent support for building the &Qt; library (in case the &kde; software you are trying to build depends on a recent &Qt; not available in your distribution). &kdesrc-build; does not require a GUI present to operate. So, you can build &kde; software without needing a graphical environment. Supports setting default options for all modules (such as the compilation settings or the configuration options). Such options can normally be changed for specific modules as well. Also, &kdesrc-build; will add standard flags as appropriate to save you the trouble and possible errors from typing them yourself. Nota Bene: this does not apply when a (custom) toolchain is configured through e.g.: cmake-toolchain &kdesrc-build; can checkout a specific branch or tag of a module. You can also ensure that a specific revision is checked out of a module. &kdesrc-build; can automatically switch a source directory to checkout from a different repository, branch, or tag. This happens automatically when you change an option that changes what the repository &url; should be, but you must use the --src-only option to let &kdesrc-build; know that it is acceptable to perform the switch. &kdesrc-build; can checkout only portions of a module, for those situations where you only need one program from a large module. For developers: &kdesrc-build; will remind you if you use git+ssh:// but ssh-agent is not running, as this will lead to repeated password requests from &ssh;. Can delete the build directory of a module after its installation to save space at the expense of future compilation time. The locations for the directories used by &kdesrc-build; are configurable (even per module). Can use &sudo;, or a different user-specified command to install modules so that &kdesrc-build; does not need to be run as the super user. &kdesrc-build; runs with reduced priority by default to allow you to still use your computer while &kdesrc-build; is working. Has support for using &kde;'s tags and branches. There is support for resuming a build from a given module. You can even ignore some modules temporarily for a given build. &kdesrc-build; will show the progress of your build when using &cmake;, and will always time the build process so you know after the fact how long it took. Comes built-in with a sane set of default options appropriate for building a base &kde; single-user installation from the anonymous source repositories. Tilde-expansion for your configuration options. For example, you can specify: install-dir ~/kde/usr Automatically sets up a build system, with the source directory not the same as the build directory, in order to keep the source directory pristine. You can specify global options to apply to every module to check out, and you can specify options to apply to individual modules as well. Forced full rebuilds, by running &kdesrc-build; with the --refresh-build option. You can specify various environment values to be used during the build, including DO_NOT_COMPILE and CXXFLAGS. Command logging. Logs are dated and numbered so that you always have a log of a script run. Also, a special symlink called latest is created to always point to the most recent log entry in the log directory. &kdesrc-build-logging;
