<h1 class="settitle">Prerequisites for GCC</h1>
<a name="index-Prerequisites-1"></a>
GCC requires that various tools and packages be available for use in the
build procedure. Modifying GCC sources requires additional tools
described below.
<h3 class="heading"><a name="TOC0"></a>Tools/packages necessary for building GCC</h3>
<dl>
<dt>ISO C90 compiler<dd>Necessary to bootstrap GCC, although versions of GCC prior
to 3.4 also allow bootstrapping with a traditional (K&R) C compiler.
<p>To build all languages in a cross-compiler or other configuration where
3-stage bootstrap is not performed, you need to start with an existing
GCC binary (version 2.95 or later) because source code for language
frontends other than C might use GCC extensions.
<br><dt>GNAT<dd>
In order to build the Ada compiler (GNAT) you must already have GNAT
installed because portions of the Ada frontend are written in Ada (with
GNAT extensions.) Refer to the Ada installation instructions for more
specific information.
<br><dt>A “working” POSIX compatible shell, or GNU bash<dd>
Necessary when running <samp><span class="command">configure</span></samp> because some
<samp><span class="command">/bin/sh</span></samp> shells have bugs and may crash when configuring the
target libraries. In other cases, <samp><span class="command">/bin/sh</span></samp> or <samp><span class="command">ksh</span></samp>
have disastrous corner-case performance problems. This
can cause target <samp><span class="command">configure</span></samp> runs to literally take days to
complete in some cases.
<p>So on some platforms <samp><span class="command">/bin/ksh</span></samp> is sufficient, on others it
isn't. See the host/target specific instructions for your platform, or
use <samp><span class="command">bash</span></samp> to be sure. Then set <samp><span class="env">CONFIG_SHELL</span></samp> in your
environment to your “good” shell prior to running
<samp><span class="command">configure</span></samp>/<samp><span class="command">make</span></samp>.
<p><samp><span class="command">zsh</span></samp> is not a fully compliant POSIX shell and will not
work when configuring GCC.
<br><dt>A POSIX or SVR4 awk<dd>
Necessary for creating some of the generated source files for GCC.
If in doubt, use a recent GNU awk version, as some of the older ones
are broken. GNU awk version 3.1.5 is known to work.
<br><dt>GNU binutils<dd>
Necessary in some circumstances, optional in others. See the
host/target specific instructions for your platform for the exact
requirements.
<br><dt>gzip version 1.2.4 (or later) or<dt>bzip2 version 1.0.2 (or later)<dd>
Necessary to uncompress GCC <samp><span class="command">tar</span></samp> files when source code is
obtained via FTP mirror sites.
<br><dt>GNU make version 3.80 (or later)<dd>
You must have GNU make installed to build GCC.
<br><dt>GNU tar version 1.14 (or later)<dd>
Necessary (only on some platforms) to untar the source code. Many
systems' <samp><span class="command">tar</span></samp> programs will also work, only try GNU
<samp><span class="command">tar</span></samp> if you have problems.
<br><dt>Perl version 5.6.1 (or later)<dd>
Necessary when targetting Darwin, building ‘<samp><span class="samp">libstdc++</span></samp>’,
and not using <samp><span class="option">--disable-symvers</span></samp>.
Necessary when targetting Solaris 2 with Sun <samp><span class="command">ld</span></samp> and not using
<samp><span class="option">--disable-symvers</span></samp>. The bundled <samp><span class="command">perl</span></samp> in Solaris 8
and up works.
<p>Necessary when regenerating <samp><span class="file">Makefile</span></samp> dependencies in libiberty.
Necessary when regenerating <samp><span class="file">libiberty/functions.texi</span></samp>.
Necessary when generating manpages from Texinfo manuals.
Used by various scripts to generate some files included in SVN (mainly
Unicode-related and rarely changing) from source tables.
<br><dt><samp><span class="command">jar</span></samp>, or InfoZIP (<samp><span class="command">zip</span></samp> and <samp><span class="command">unzip</span></samp>)<dd>
Necessary to build libgcj, the GCJ runtime.
</dl>
<p>Several support libraries are necessary to build GCC, some are required,
others optional. While any sufficiently new version of required tools
usually work, library requirements are generally stricter. Newer
versions may work in some cases, but it's safer to use the exact
versions documented. We appreciate bug reports about problems with
newer versions, though. If your OS vendor provides packages for the
support libraries then using those packages may be the simplest way to
install the libraries.
<dl>
<dt>GNU Multiple Precision Library (GMP) version 4.3.2 (or later)<dd>
Necessary to build GCC. If a GMP source distribution is found in a
subdirectory of your GCC sources named <samp><span class="file">gmp</span></samp>, it will be built
together with GCC. Alternatively, if GMP is already installed but it
is not in your library search path, you will have to configure with the
<samp><span class="option">--with-gmp</span></samp> configure option. See also <samp><span class="option">--with-gmp-lib</span></samp>
and <samp><span class="option">--with-gmp-include</span></samp>.
<br><dt>MPFR Library version 2.4.2 (or later)<dd>
Necessary to build GCC. It can be downloaded from
<a href="http://www.mpfr.org/">http://www.mpfr.org/</a>. If an MPFR source distribution is found
in a subdirectory of your GCC sources named <samp><span class="file">mpfr</span></samp>, it will be
built together with GCC. Alternatively, if MPFR is already installed
but it is not in your default library search path, the
<samp><span class="option">--with-mpfr</span></samp> configure option should be used. See also
<samp><span class="option">--with-mpfr-lib</span></samp> and <samp><span class="option">--with-mpfr-include</span></samp>.
<br><dt>MPC Library version 0.8.1 (or later)<dd>
Necessary to build GCC. It can be downloaded from
<a href="http://www.multiprecision.org/">http://www.multiprecision.org/</a>. If an MPC source distribution
is found in a subdirectory of your GCC sources named <samp><span class="file">mpc</span></samp>, it
will be built together with GCC. Alternatively, if MPC is already
installed but it is not in your default library search path, the
<samp><span class="option">--with-mpc</span></samp> configure option should be used. See also
<samp><span class="option">--with-mpc-lib</span></samp> and <samp><span class="option">--with-mpc-include</span></samp>.
<br><dt>Parma Polyhedra Library (PPL) version 0.11<dd>
Necessary to build GCC with the Graphite loop optimizations.
It can be downloaded from <a href="http://www.cs.unipr.it/ppl/Download/">http://www.cs.unipr.it/ppl/Download/</a>.
<p>The <samp><span class="option">--with-ppl</span></samp> configure option should be used if PPL is not
installed in your default library search path.
<br><dt>CLooG-PPL version 0.15 or CLooG 0.16<dd>
Necessary to build GCC with the Graphite loop optimizations. There
are two versions available. CLooG-PPL 0.15 as well as CLooG 0.16.
The former is the default right now. It can be downloaded from
<a href="ftp://gcc.gnu.org/pub/gcc/infrastructure/">ftp://gcc.gnu.org/pub/gcc/infrastructure/</a> as
<samp><span class="file">cloog-ppl-0.15.tar.gz</span></samp>.
<p>CLooG 0.16 support is still in testing stage, but will be the
default in future GCC releases. It is also available at
<a href="ftp://gcc.gnu.org/pub/gcc/infrastructure/">ftp://gcc.gnu.org/pub/gcc/infrastructure/</a> as
<samp><span class="file">cloog-0.16.1.tar.gz</span></samp>. To use it add the additional configure
option <samp><span class="option">--enable-cloog-backend=isl</span></samp>. Even if CLooG 0.16
does not use PPL, PPL is still required for Graphite.
<p>In both cases <samp><span class="option">--with-cloog</span></samp> configure option should be used
if CLooG is not installed in your default library search path.
</dl>
<h3 class="heading"><a name="TOC1"></a>Tools/packages necessary for modifying GCC</h3>
<dl>
<dt>autoconf version 2.64<dt>GNU m4 version 1.4.6 (or later)<dd>
Necessary when modifying <samp><span class="file">configure.ac</span></samp>, <samp><span class="file">aclocal.m4</span></samp>, etc.
to regenerate <samp><span class="file">configure</span></samp> and <samp><span class="file">config.in</span></samp> files.
<br><dt>automake version 1.11.1<dd>
Necessary when modifying a <samp><span class="file">Makefile.am</span></samp> file to regenerate its
associated <samp><span class="file">Makefile.in</span></samp>.
<p>Much of GCC does not use automake, so directly edit the <samp><span class="file">Makefile.in</span></samp>
file. Specifically this applies to the <samp><span class="file">gcc</span></samp>, <samp><span class="file">intl</span></samp>,
<samp><span class="file">libcpp</span></samp>, <samp><span class="file">libiberty</span></samp>, <samp><span class="file">libobjc</span></samp> directories as well
as any of their subdirectories.
<p>For directories that use automake, GCC requires the latest release in
the 1.11 series, which is currently 1.11.1. When regenerating a directory
to a newer version, please update all the directories using an older 1.11
to the latest released version.
<br><dt>gettext version 0.14.5 (or later)<dd>
Needed to regenerate <samp><span class="file">gcc.pot</span></samp>.
<br><dt>gperf version 2.7.2 (or later)<dd>
Necessary when modifying <samp><span class="command">gperf</span></samp> input files, e.g.
<samp><span class="file">gcc/cp/cfns.gperf</span></samp> to regenerate its associated header file, e.g.
<samp><span class="file">gcc/cp/cfns.h</span></samp>.
<br><dt>DejaGnu 1.4.4<dt>Expect<dt>Tcl<dd>
Necessary to run the GCC testsuite; see the section on testing for details.
<br><dt>autogen version 5.5.4 (or later) and<dt>guile version 1.4.1 (or later)<dd>
Necessary to regenerate <samp><span class="file">fixinc/fixincl.x</span></samp> from
<samp><span class="file">fixinc/inclhack.def</span></samp> and <samp><span class="file">fixinc/*.tpl</span></samp>.
<p>Necessary to run ‘<samp><span class="samp">make check</span></samp>’ for <samp><span class="file">fixinc</span></samp>.
<p>Necessary to regenerate the top level <samp><span class="file">Makefile.in</span></samp> file from
<samp><span class="file">Makefile.tpl</span></samp> and <samp><span class="file">Makefile.def</span></samp>.
<br><dt>Flex version 2.5.4 (or later)<dd>
Necessary when modifying <samp><span class="file">*.l</span></samp> files.
<p>Necessary to build GCC during development because the generated output
files are not included in the SVN repository. They are included in
releases.
<br><dt>Texinfo version 4.7 (or later)<dd>
Necessary for running <samp><span class="command">makeinfo</span></samp> when modifying <samp><span class="file">*.texi</span></samp>
files to test your changes.
<p>Necessary for running <samp><span class="command">make dvi</span></samp> or <samp><span class="command">make pdf</span></samp> to
create printable documentation in DVI or PDF format. Texinfo version
4.8 or later is required for <samp><span class="command">make pdf</span></samp>.
<p>Necessary to build GCC documentation during development because the
generated output files are not included in the SVN repository. They are
included in releases.
<br><dt>TeX (any working version)<dd>
Necessary for running <samp><span class="command">texi2dvi</span></samp> and <samp><span class="command">texi2pdf</span></samp>, which
are used when running <samp><span class="command">make dvi</span></samp> or <samp><span class="command">make pdf</span></samp> to create
DVI or PDF files, respectively.
<br><dt>SVN (any version)<dt>SSH (any version)<dd>
Necessary to access the SVN repository. Public releases and weekly
snapshots of the development sources are also available via FTP.
<br><dt>GNU diffutils version 2.7 (or later)<dd>
Useful when submitting patches for the GCC source code.
<br><dt>patch version 2.5.4 (or later)<dd>
Necessary when applying patches, created with <samp><span class="command">diff</span></samp>, to one's
own sources.
<br><dt>ecj1<dt>gjavah<dd>
If you wish to modify <samp><span class="file">.java</span></samp> files in libjava, you will need to
configure with <samp><span class="option">--enable-java-maintainer-mode</span></samp>, and you will need
to have executables named <samp><span class="command">ecj1</span></samp> and <samp><span class="command">gjavah</span></samp> in your path.
The <samp><span class="command">ecj1</span></samp> executable should run the Eclipse Java compiler via
the GCC-specific entry point. You can download a suitable jar from
<a href="ftp://sourceware.org/pub/java/">ftp://sourceware.org/pub/java/</a>, or by running the script
<samp><span class="command">contrib/download_ecj</span></samp>.
<br><dt>antlr.jar version 2.7.1 (or later)<dt>antlr binary<dd>
If you wish to build the <samp><span class="command">gjdoc</span></samp> binary in libjava, you will
need to have an <samp><span class="file">antlr.jar</span></samp> library available. The library is
searched for in system locations but can be specified with
<samp><span class="option">--with-antlr-jar=</span></samp> instead. When configuring with
<samp><span class="option">--enable-java-maintainer-mode</span></samp>, you will need to have one of
the executables named <samp><span class="command">cantlr</span></samp>, <samp><span class="command">runantlr</span></samp> or
<samp><span class="command">antlr</span></samp> in your path.
