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

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.

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

489 build with and without profiling, then use the following for the

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 @code{make doc} compiles the documents for all languages. To save
651 some compile time, the English language documents can be compiled
658 Compilation of documentation in Info format with images can be
659 done separately by issuing:
667 If source files have changed since the last documentation build,
668 output files that need to be rebuilt are normally rebuilt, even if
669 you do not run @code{make@tie{}doc-clean} first. However, build
670 dependencies in the documentation are so complex that some
671 newly-edited files may not be rebuilt as they should be; a
672 workaround is to @command{touch} the top source file for any
673 manual you've edited. For example, if you make changes to a file
674 in @file{notation/}, do:
677 touch Documentation/notation.tely
681 The top sources possibly affected by this are:
684 Documentation/extend.texi
685 Documentation/changes.tely
686 Documentation/contributor.texi
687 Documentation/essay.tely
688 Documentation/extending.tely
689 Documentation/learning.tely
690 Documentation/notation.tely
691 Documentation/snippets.tely
692 Documentation/usage.tely
693 Documentation/web.texi
697 You can @command{touch} all of them at once with:
700 touch Documentation/*te??
704 However, this will rebuild all of the manuals
705 indiscriminately---it is more efficient to @command{touch} only
708 @node Building a single document
709 @unnumberedsubsubsec Building a single document
710 It's possible to build a single document. For example, to rebuild
711 only @file{contributor.pdf}, do the following:
716 touch ../../Documentation/contributor.texi
717 make out=www out-www/contributor.pdf
720 If you are only working on a single document, test-building it in
721 this way can give substantial time savings - recreating
722 @file{contributor.pdf}, for example, takes a matter of seconds.
724 @node Saving time with CPU_COUNT
725 @unnumberedsubsubsec Saving time with @code{CPU_COUNT}
727 The most time consuming task for building the documentation is
728 running LilyPond to build images of music, and there cannot be
729 several simultaneously running @command{lilypond-book} instances,
730 so the @option{-j} @command{make} option does not significantly
731 speed up the build process. To help speed it up, the makefile
732 variable @option{CPU_COUNT} may be set in @file{local.make} or on
733 the command line to the number of @code{.ly} files that LilyPond
734 should process simultaneously, e.g. on a bi-processor or dual core
738 make -j3 CPU_COUNT=3 doc
742 The recommended value of @option{CPU_COUNT} is one plus the number
743 of cores or processors, but it is advisable to set it to a smaller
744 value unless your system has enough RAM to run that many
745 simultaneous LilyPond instances. Also, values for the @option{-j}
746 option that pose problems with @samp{make} are less likely to pose
747 problems with @samp{make doc} (this applies to both @option{-j}
748 and @option{CPU_COUNT}). For example, with a quad-core processor,
749 it is possible for @samp{make -j5 CPU_COUNT=5 doc} to work
750 consistently even if @samp{make -j5} rarely succeeds.
754 @unnumberedsubsubsec AJAX search
756 To build the documentation with interactive searching, use:

794 target creates symbolic links to HTML and PDF installed documentation
795 tree in @file{@var{prefix}/share/info}, in order to save disk space,
796 whereas @code{install-info} copies images in

799 It is possible to build a documentation tree in
800 @file{out-www/online-root/}, with special processing, so it can be
801 used on a website with content negotiation for automatic language
802 selection; this can be achieved by issuing

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

948 export PATH=/opt/local/bin:/opt/local/sbin:$PATH
949 export DYLD_FALLBACK_LIBRARY_PATH=/opt/local/lib:$DYLD_FALLBACK_LIBRARY_PATH
952 Now you must edit the generated @file{config.make} file. Change
955 FLEXLEXER_FILE = /usr/include/FlexLexer.h
962 FLEXLEXER_FILE = /opt/local/include/FlexLexer.h
965 At this point, you should verify that you have the appropriate
966 fonts installed with your ghostscript installation. Check @code{ls
967 /opt/local/share/ghostscript/fonts} for: 'c0590*' files (.pfb,
968 .pfb and .afm). If you don't have them, run the following
969 commands to grab them from the ghostscript SVN server and install
970 them in the appropriate location:
973 svn export http://svn.ghostscript.com/ghostscript/tags/urw-fonts-1.0.7pre44/
974 sudo mv urw-fonts-1.0.7pre44/* /opt/local/share/ghostscript/fonts/
975 rm -rf urw-fonts-1.07pre44
978 Now run the @code{./configure} script. To avoid complications with
979 automatic font detection, add
982 --with-ncsb-dir=/opt/local/share/ghostscript/fonts
986 @unnumberedsubsubsec Solaris
988 Solaris7, ./configure
990 @file{./configure} needs a POSIX compliant shell. On Solaris7,
991 @file{/bin/sh} is not yet POSIX compliant, but @file{/bin/ksh} or bash
992 is. Run configure like
995 CONFIG_SHELL=/bin/ksh ksh -c ./configure
1002 CONFIG_SHELL=/bin/bash bash -c ./configure
1005 @unnumberedsubsubsec FreeBSD
1007 To use system fonts, dejaview must be installed. With the default
1008 port, the fonts are installed in @file{usr/X11R6/lib/X11/fonts/dejavu}.
1010 Open the file @file{$LILYPONDBASE/usr/etc/fonts/local.conf} and add the
1011 following line just after the @code{<fontconfig>} line. (Adjust as necessary
1012 for your hierarchy.)
1015 <dir>/usr/X11R6/lib/X11/fonts</dir>
1019 @unnumberedsubsubsec International fonts
1021 On Mac OS X, all fonts are installed by default. However, finding all
1022 system fonts requires a bit of configuration; see
1023 @uref{http://lists.gnu.org/archive/html/lilypond-user/2007-03/msg00472.html,
1024 this post} on the @code{lilypond-user} mailing list.
1026 On Linux, international fonts are installed by different means on
1027 every distribution. We cannot list the exact commands or packages
1028 that are necessary, as each distribution is different, and the exact
1029 package names within each distribution changes. Here are some

1046 @unnumberedsubsubsec Using lilypond python libraries
1048 If you want to use lilypond's python libraries (either running
1049 certain build scripts manually, or using them in other programs),
1050 set @code{PYTHONPATH} to @file{python/out} in your build
1051 directory, or @file{.../usr/lib/lilypond/current/python} in the
1052 installation directory structure.
1057 @node Concurrent stable and development versions
1058 @section Concurrent stable and development versions
1061 It can be useful to have both the stable and the development versions
1062 of Lilypond available at once. One way to do this on GNU/Linux is to
1063 install the stable version using the precompiled binary, and run the
1064 development version from the source tree. After running @command{make
1065 all} from the top directory of the Lilypond source files, there will
1066 be a binary called @code{lilypond} in the @code{out} directory:
1069 <@var{path to}>/lilypond/out/bin/lilypond
1072 This binary can be run without actually doing the @code{make
1073 install} command. The advantage to this is that you can have all
1074 of the latest changes available after pulling from git and running
1075 @code{make all}, without having to uninstall the old version and
1078 So, to use the stable version, install it as usual and use the
1085 To use the development version, create a link to the binary in the
1086 source tree by saving the following line in a file somewhere in your
1090 exec <@var{path to}>/lilypond/out/bin/lilypond "$@@"
1093 Save it as @code{Lilypond} (with a capital L to distinguish it
1094 from the stable @code{lilypond}), and make it executable:
1100 Then you can invoke the development version this way:

1116 We currently use make and stepmake, which is complicated and only
