24 @section Overview of compiling
26 Compiling LilyPond from source is an involved process, and is only
27 recommended for developers and packagers. Typical program users
28 are instead encouraged to obtain the program from a package
29 manager (on Unix) or by downloading a precompiled binary
30 configured for a specific operating system. Pre-compiled binaries
31 are available on the @rweb{Download} page.
33 Compiling LilyPond from source is necessary if you want to build,
34 install, or test your own version of the program.
36 A successful compile can also be used to generate and install the
37 documentation, incorporating any changes you may have made.
38 However, a successful compile is not a requirement for generating
39 the documentation. The documentation can be built using a Git
40 repository in conjunction with a locally installed copy of the
41 program. For more information, see @ref{Building documentation
44 Attempts to compile LilyPond natively on Windows have been
45 unsuccessful, though a workaround is available (see

463 @subsection Saving time with the @option{-j} option
465 If your system has multiple CPUs, you can speed up compilation by
466 adding @samp{-j@var{X}} to the @command{make} command, where
467 @samp{@var{X}} is one more than the number of cores you have. For
468 example, a typical Core2Duo machine would use:
474 If you get errors using the @option{-j} option, and @samp{make}
475 succeeds without it, try lowering the @code{@var{X}} value.
477 Because multiple jobs run in parallel when @option{-j} is used, it can
478 be difficult to determine the source of an error when one occurs. In
479 that case, running @samp{make} without the @option{-j} is advised.
481 @node Compiling for multiple platforms

484 If you want to build multiple versions of LilyPond with different
485 configuration settings, you can use the
486 @option{--enable-config=@var{conf}} option of @command{configure}.
487 You should use @code{make@tie{}conf=@var{conf}} to generate the
488 output in @file{out-@var{conf}}. For example, suppose you want to
489 build with and without profiling, then use the following for the

540 If you configured @command{make} to install your local build in a

550 If instead, your installation directory is not one that you can
551 normally write to (such as the default @file{/usr/local/}, which

553 temporarily become the superuser when running
554 @command{make@tie{}install}:

625 @node Building documentation
626 @unnumberedsubsubsec Building documentation
628 After a successful compile (using @command{make}), the
629 documentation can be built by issuing:
635 The first time you run @command{make@tie{}doc}, the process can
636 easily take an hour or more. After that, @command{make@tie{}doc}
637 only makes changes to the pre-built documentation where needed,
638 so it may only take a minute or two to test changes if the
639 documentation is already built.
641 If @command{make@tie{}doc} succeeds, the HTML documentation tree
642 is available in @file{out-www/offline-root/}, and can be browsed
643 locally. Various portions of the documentation can be found by
644 looking in @file{out/} and @file{out-www} subdirectories in other
645 places in the source tree, but these are only @emph{portions} of
646 the docs. Please do not complain about anything which is broken
647 in those places; the only complete set of documentation is in
648 @file{out-www/offline-root/} from the top of the source tree.
650 Compilation of documentation in Info format with images can be
651 done separately by issuing:
659 If source files have changed since the last documentation build,
660 output files that need to be rebuilt are normally rebuilt, even if
661 you do not run @code{make@tie{}doc-clean} first. However, build
662 dependencies in the documentation are so complex that some
663 newly-edited files may not be rebuilt as they should be; a
664 workaround is to @command{touch} the top source file for any
665 manual you've edited. For example, if you make changes to a file
666 in @file{notation/}, do:
669 touch Documentation/notation.tely
673 The top sources possibly affected by this are:
676 Documentation/extend.texi
677 Documentation/changes.tely
678 Documentation/contributor.texi
679 Documentation/essay.tely
680 Documentation/extending.tely
681 Documentation/learning.tely
682 Documentation/notation.tely
683 Documentation/snippets.tely
684 Documentation/usage.tely
685 Documentation/web.texi
689 You can @command{touch} all of them at once with:
692 touch Documentation/*te??
696 However, this will rebuild all of the manuals
697 indiscriminately---it is more efficient to @command{touch} only
700 @node Building a single document
701 @unnumberedsubsubsec Building a single document
702 It's possible to build a single document. For example, to rebuild
703 only @file{contributor.pdf}, do the following:
708 touch ../../Documentation/contributor.texi
709 make out=www out-www/contributor.pdf
712 If you are only working on a single document, test-building it in
713 this way can give substantial time savings - recreating
714 @file{contributor.pdf}, for example, takes a matter of seconds.
716 @node Saving time with CPU_COUNT
717 @unnumberedsubsubsec Saving time with @code{CPU_COUNT}
719 The most time consuming task for building the documentation is
720 running LilyPond to build images of music, and there cannot be
721 several simultaneously running @command{lilypond-book} instances,
722 so the @option{-j} @command{make} option does not significantly
723 speed up the build process. To help speed it up, the makefile
724 variable @option{CPU_COUNT} may be set in @file{local.make} or on
725 the command line to the number of @code{.ly} files that LilyPond
726 should process simultaneously, e.g. on a bi-processor or dual core
730 make -j3 CPU_COUNT=3 doc
734 The recommended value of @option{CPU_COUNT} is one plus the number
735 of cores or processors, but it is advisable to set it to a smaller
736 value unless your system has enough RAM to run that many
737 simultaneous LilyPond instances. Also, values for the @option{-j}
738 option that pose problems with @samp{make} are less likely to pose
739 problems with @samp{make doc} (this applies to both @option{-j}
740 and @option{CPU_COUNT}). For example, with a quad-core processor,
741 it is possible for @samp{make -j5 CPU_COUNT=5 doc} to work
742 consistently even if @samp{make -j5} rarely succeeds.
746 @unnumberedsubsubsec AJAX search
748 To build the documentation with interactive searching, use:

785 Note that to get the images in Info documentation, @code{install-doc}
786 target creates symbolic links to HTML and PDF installed documentation
787 tree in @file{@var{prefix}/share/info}, in order to save disk space,
788 whereas @code{install-info} copies images in
789 @file{@var{prefix}/share/info} subdirectories.
791 It is possible to build a documentation tree in
792 @file{out-www/online-root/}, with special processing, so it can be
793 used on a website with content negotiation for automatic language
794 selection; this can be achieved by issuing
797 make WEB_TARGETS=online doc

846 You may build the manual without building all the @file{input/*} stuff

941 export DYLD_FALLBACK_LIBRARY_PATH=/opt/local/lib:$DYLD_FALLBACK_LIBRARY_PATH
944 Now you must edit the generated @file{config.make} file. Change
947 FLEXLEXER_FILE = /usr/include/FlexLexer.h
954 FLEXLEXER_FILE = /opt/local/include/FlexLexer.h
957 At this point, you should verify that you have the appropriate
958 fonts installed with your ghostscript installation. Check @code{ls
959 /opt/local/share/ghostscript/fonts} for: 'c0590*' files (.pfb,
960 .pfb and .afm). If you don't have them, run the following
961 commands to grab them from the ghostscript SVN server and install
962 them in the appropriate location:
965 svn export http://svn.ghostscript.com/ghostscript/tags/urw-fonts-1.0.7pre44/
966 sudo mv urw-fonts-1.0.7pre44/* /opt/local/share/ghostscript/fonts/
967 rm -rf urw-fonts-1.07pre44
970 Now run the @code{./configure} script. To avoid complications with
971 automatic font detection, add
974 --with-ncsb-dir=/opt/local/share/ghostscript/fonts
978 @unnumberedsubsubsec Solaris
980 Solaris7, ./configure
982 @file{./configure} needs a POSIX compliant shell. On Solaris7,
983 @file{/bin/sh} is not yet POSIX compliant, but @file{/bin/ksh} or bash
984 is. Run configure like
987 CONFIG_SHELL=/bin/ksh ksh -c ./configure
994 CONFIG_SHELL=/bin/bash bash -c ./configure
997 @unnumberedsubsubsec FreeBSD
999 To use system fonts, dejaview must be installed. With the default
1000 port, the fonts are installed in @file{usr/X11R6/lib/X11/fonts/dejavu}.
1002 Open the file @file{$LILYPONDBASE/usr/etc/fonts/local.conf} and add the
1003 following line just after the @code{<fontconfig>} line. (Adjust as necessary
1004 for your hierarchy.)

1011 @unnumberedsubsubsec International fonts
1013 On Mac OS X, all fonts are installed by default. However, finding all
1014 system fonts requires a bit of configuration; see
1015 @uref{http://lists.gnu.org/archive/html/lilypond-user/2007-03/msg00472.html,
1016 this post} on the @code{lilypond-user} mailing list.
1018 On Linux, international fonts are installed by different means on
1019 every distribution. We cannot list the exact commands or packages
1020 that are necessary, as each distribution is different, and the exact
1021 package names within each distribution changes. Here are some

1038 @unnumberedsubsubsec Using lilypond python libraries
1040 If you want to use lilypond's python libraries (either running
1041 certain build scripts manually, or using them in other programs),
1042 set @code{PYTHONPATH} to @file{python/out} in your build
1043 directory, or @file{.../usr/lib/lilypond/current/python} in the
1044 installation directory structure.
1049 @node Concurrent stable and development versions
1050 @section Concurrent stable and development versions
1053 It can be useful to have both the stable and the development versions
1054 of Lilypond available at once. One way to do this on GNU/Linux is to
1055 install the stable version using the precompiled binary, and run the
1056 development version from the source tree. After running @command{make
1057 all} from the top directory of the Lilypond source files, there will
1058 be a binary called @code{lilypond} in the @code{out} directory:
1061 <@var{path to}>/lilypond/out/bin/lilypond
1064 This binary can be run without actually doing the @code{make
1065 install} command. The advantage to this is that you can have all
1066 of the latest changes available after pulling from git and running
1067 @code{make all}, without having to uninstall the old version and
1070 So, to use the stable version, install it as usual and use the
1077 To use the development version, create a link to the binary in the
1078 source tree by saving the following line in a file somewhere in your
1082 exec <@var{path to}>/lilypond/out/bin/lilypond "$@@"
1085 Save it as @code{Lilypond} (with a capital L to distinguish it
1086 from the stable @code{lilypond}), and make it executable:
1092 Then you can invoke the development version this way:

1108 We currently use make and stepmake, which is complicated and only
