13.2 Environment variables
Some maintenance scripts and instructions in this guide rely on the following environment variables. They should be predefined in LilyDev distribution (see LilyDev); if you set up your own development environment, you can set them by appending these settings to your ~/.bashrc (or whatever defines your default environment variables for the user account for LilyPond development), then logging out and in (adapt directories to your setup):
LILYPOND_GIT=~/lilypond-git export LILYPOND_GIT LILYPOND_BUILD_DIR=~/lilypond-git/build export LILYPOND_BUILD_DIR
The standard build and install procedure (with autogen.sh,
configure, make, make install, make doc
…) does not rely on them.
