4.2. Supported Environment Variables

HOME
Used for tilde-expansion of file names, and is the default base for the source, build, and installation directories.

PATH
This environment variable controls the default search path for executables. You can use the binpath configuration file option to add to this variable (e.g. for running from cron(8)).

LC_*
Environment variables starting with LC_ control the locale used by kde-builder. Although kde-builder is still not localizable at this point, many of the commands it uses are. kde-builder normally sets LC_ALL=C for commands that it must examine the output of, but you can manually do this as well. If setting LC_ALL=C fixes a kde-builder problem please submit a bug report.

SSH_AGENT_PID
This environment variable is checked to see if ssh-agent(1) is running, but only if kde-builder determines that you are checking out a project that requires an SSH login (but you should know this as no project requires this by default).

KDE_BUILDER_USE_TTY
If set, this variable forces kde-builder not to close its input while executing system processes. Normally kde-builder closes stdin since the stdout and stderr for its child processes are redirected and therefore the user would never see an input prompt anyway.

others
Many programs are used by kde-builder in the course of its execution, including git(1), make(1), and cmake(1). Each of these programs may have their own response to environment variables being set. kde-builder will pass environment variables that are set when it is run onto these processes. You can ensure certain environment variables (e.g. CC or CXX) are set by using the set-env configuration file option.
