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.

associated <samp><span class="file">Makefile.in</span></samp>.
|
||
|
|
|
