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

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

624 @node Building documentation
625 @unnumberedsubsubsec Building documentation
627 After a successful compile (using @command{make}), the
628 documentation can be built by issuing:
634 The first time you run @command{make@tie{}doc}, the process can
635 easily take an hour or more. After that, @command{make@tie{}doc}
636 only makes changes to the pre-built documentation where needed,
637 so it may only take a minute or two to test changes if the
638 documentation is already built.
640 If @command{make@tie{}doc} succeeds, the HTML documentation tree
641 is available in @file{out-www/offline-root/}, and can be browsed
642 locally. Various portions of the documentation can be found by
643 looking in @file{out/} and @file{out-www} subdirectories in other
644 places in the source tree, but these are only @emph{portions} of
645 the docs. Please do not complain about anything which is broken
646 in those places; the only complete set of documentation is in
647 @file{out-www/offline-root/} from the top of the source tree.
649 @code{make doc} compiles the documents for all languages. To save
650 some compile time, the English language documents can be compiled
657 @noindent Similarly, it is possible to compile a subset of the
658 translated documentation by specifying their language codes on the
659 command line. For example, the French and German translations are
663 make LANGS='de fr' doc
666 @noindent Note that this will also compile the English version.
668 Compilation of documentation in Info format with images can be
669 done separately by issuing:
676 An issue when switching branches between master and lilypond/translation
677 is the appearance/disappearance of translated versions of some manuals.
678 If you see such a warning from make:
681 No rule to make target `X', needed by `Y'
685 Your best bet is to delete the file Y.dep and to try again.
687 @node Building a single document
688 @unnumberedsubsubsec Building a single document
689 It's possible to build a single document. For example, to rebuild
690 only @file{contributor.pdf}, do the following:
695 touch ../../Documentation/contributor.texi
696 make out=www out-www/contributor.pdf
699 If you are only working on a single document, test-building it in
700 this way can give substantial time savings - recreating
701 @file{contributor.pdf}, for example, takes a matter of seconds.
703 @node Saving time with CPU_COUNT
704 @unnumberedsubsubsec Saving time with @code{CPU_COUNT}
706 The most time consuming task for building the documentation is
707 running LilyPond to build images of music, and there cannot be
708 several simultaneously running @command{lilypond-book} instances,
709 so the @option{-j} @command{make} option does not significantly
710 speed up the build process. To help speed it up, the makefile
711 variable @option{CPU_COUNT} may be set in @file{local.make} or on
712 the command line to the number of @code{.ly} files that LilyPond
713 should process simultaneously, e.g. on a bi-processor or dual core
717 make -j3 CPU_COUNT=3 doc
721 The recommended value of @option{CPU_COUNT} is one plus the number
722 of cores or processors, but it is advisable to set it to a smaller
723 value unless your system has enough RAM to run that many
724 simultaneous LilyPond instances. Also, values for the @option{-j}
725 option that pose problems with @samp{make} are less likely to pose
726 problems with @samp{make doc} (this applies to both @option{-j}
727 and @option{CPU_COUNT}). For example, with a quad-core processor,
728 it is possible for @samp{make -j5 CPU_COUNT=5 doc} to work
729 consistently even if @samp{make -j5} rarely succeeds.
733 @unnumberedsubsubsec AJAX search
735 To build the documentation with interactive searching, use:

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

780 used on a website with content negotiation for automatic language
781 selection; this can be achieved by issuing

947 .pfb and .afm). If you don't have them, run the following
948 commands to grab them from the ghostscript SVN server and install
949 them in the appropriate location:
952 svn export http://svn.ghostscript.com/ghostscript/tags/urw-fonts-1.0.7pre44/
953 sudo mv urw-fonts-1.0.7pre44/* /opt/local/share/ghostscript/fonts/
954 rm -rf urw-fonts-1.07pre44
957 Now run the @code{./configure} script. To avoid complications with
958 automatic font detection, add
961 --with-ncsb-dir=/opt/local/share/ghostscript/fonts
965 @unnumberedsubsubsec Solaris
967 Solaris7, ./configure
969 @file{./configure} needs a POSIX compliant shell. On Solaris7,
970 @file{/bin/sh} is not yet POSIX compliant, but @file{/bin/ksh} or bash
971 is. Run configure like
974 CONFIG_SHELL=/bin/ksh ksh -c ./configure
981 CONFIG_SHELL=/bin/bash bash -c ./configure
984 @unnumberedsubsubsec FreeBSD
986 To use system fonts, dejaview must be installed. With the default
987 port, the fonts are installed in @file{usr/X11R6/lib/X11/fonts/dejavu}.
989 Open the file @file{$LILYPONDBASE/usr/etc/fonts/local.conf} and add the
990 following line just after the @code{<fontconfig>} line. (Adjust as necessary
994 <dir>/usr/X11R6/lib/X11/fonts</dir>
998 @unnumberedsubsubsec International fonts
1000 On Mac OS X, all fonts are installed by default. However, finding all
1001 system fonts requires a bit of configuration; see
1002 @uref{http://lists.gnu.org/archive/html/lilypond-user/2007-03/msg00472.html,
1003 this post} on the @code{lilypond-user} mailing list.
1005 On Linux, international fonts are installed by different means on
1006 every distribution. We cannot list the exact commands or packages
1007 that are necessary, as each distribution is different, and the exact
1008 package names within each distribution changes. Here are some

1025 @unnumberedsubsubsec Using lilypond python libraries
1027 If you want to use lilypond's python libraries (either running
1028 certain build scripts manually, or using them in other programs),
1029 set @code{PYTHONPATH} to @file{python/out} in your build
1030 directory, or @file{.../usr/lib/lilypond/current/python} in the
1031 installation directory structure.
1036 @node Concurrent stable and development versions
1037 @section Concurrent stable and development versions
1040 It can be useful to have both the stable and the development versions
1041 of Lilypond available at once. One way to do this on GNU/Linux is to
1042 install the stable version using the precompiled binary, and run the
1043 development version from the source tree. After running @command{make
1044 all} from the top directory of the Lilypond source files, there will
1045 be a binary called @code{lilypond} in the @code{out} directory:
1048 <@var{path to}>/lilypond/out/bin/lilypond
1051 This binary can be run without actually doing the @code{make
1052 install} command. The advantage to this is that you can have all
1053 of the latest changes available after pulling from git and running
1054 @code{make all}, without having to uninstall the old version and
1057 So, to use the stable version, install it as usual and use the
1064 To use the development version, create a link to the binary in the
1065 source tree by saving the following line in a file somewhere in your
1069 exec <@var{path to}>/lilypond/out/bin/lilypond "$@@"
1072 Save it as @code{Lilypond} (with a capital L to distinguish it
1073 from the stable @code{lilypond}), and make it executable:
1079 Then you can invoke the development version this way:

1095 We currently use make and stepmake, which is complicated and only
