<p>GCC requires that various tools and packages be available for use in the

<p>To build all languages in a cross-compiler or other configuration where
|
2012-03-27 23:13:14 +00:00
|
|
|
3-stage bootstrap is not performed, you need to start with an existing
|
2014-09-21 17:33:12 +00:00
|
|
|
GCC binary (version 3.4 or later) because source code for language
|
2012-03-27 23:13:14 +00:00
|
|
|
frontends other than C might use GCC extensions.
|
2014-09-21 17:33:12 +00:00
|
|
|
</p>
|
|
|
|
|
<p>Note that to bootstrap GCC with versions of GCC earlier than 3.4, you
|
|
|
|
|
may need to use <samp>--disable-stage1-checking</samp>, though
|
|
|
|
|
bootstrapping the compiler with such earlier compilers is strongly
|
|
|
|
|
discouraged.

<dt>C standard library and headers</dt>
|
|
|
|
|
<dd>
|
|
|
|
|
<p>In order to build GCC, the C standard library and headers must be present
|
|
|
|
|
for all target variants for which target libraries will be built (and not
|
|
|
|
|
only the variant of the host C++ compiler).
|
|
|
|
|
</p>
|
|
|
|
|
<p>This affects the popular ‘<samp>x86_64-unknown-linux-gnu</samp>’ platform (among
|
|
|
|
|
other multilib targets), for which 64-bit (‘<samp>x86_64</samp>’) and 32-bit
|
|
|
|
|
(‘<samp>i386</samp>’) libc headers are usually packaged separately. If you do a
|
|
|
|
|
build of a native compiler on ‘<samp>x86_64-unknown-linux-gnu</samp>’, make sure you
|
|
|
|
|
either have the 32-bit libc developer package properly installed (the exact
|
|
|
|
|
name of the package depends on your distro) or you must build GCC as a
|
|
|
|
|
64-bit only compiler by configuring with the option
|
|
|
|
|
<samp>--disable-multilib</samp>. Otherwise, you may encounter an error such as
|
|
|
|
|
‘<samp>fatal error: gnu/stubs-32.h: No such file</samp>’

<dt>GNAT</dt>

<dd>
|

|
|
<p>In order to build the Ada compiler (GNAT) you must already have GNAT
|
2012-03-27 23:13:14 +00:00
|
|
|
installed because portions of the Ada frontend are written in Ada (with
|
|
|
|
|
GNAT extensions.) Refer to the Ada installation instructions for more
|
|
|
|
|
specific information.

<dt>A “working” POSIX compatible shell, or GNU bash</dt>
|

<dd>
|

<p>Necessary when running <code>configure</code> because some
|
|
|
|
|
<code>/bin/sh</code> shells have bugs and may crash when configuring the
|
|
|
|
|
target libraries. In other cases, <code>/bin/sh</code> or <code>ksh</code>
|
2012-03-27 23:13:14 +00:00
|
|
|
have disastrous corner-case performance problems. This
|
2014-09-21 17:33:12 +00:00
|
|
|
can cause target <code>configure</code> runs to literally take days to
|
2012-03-27 23:13:14 +00:00
|
|
|
complete in some cases.
|
2014-09-21 17:33:12 +00:00
|
|
|
</p>
|
|
|
|
|
<p>So on some platforms <code>/bin/ksh</code> is sufficient, on others it
|
|
|
|
|
isn’t. See the host/target specific instructions for your platform, or
|
|
|
|
|
use <code>bash</code> to be sure. Then set <code>CONFIG_SHELL</code> in your
|
2012-03-27 23:13:14 +00:00
|
|
|
environment to your “good” shell prior to running
|
2014-09-21 17:33:12 +00:00
|
|
|
<code>configure</code>/<code>make</code>.
|
|
|
|
|
</p>
|
|
|
|
|
<p><code>zsh</code> is not a fully compliant POSIX shell and will not
|
2012-03-27 23:13:14 +00:00

work when configuring GCC.

<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
|
2014-09-21 17:33:12 +00:00
|
|
|
versions may work in some cases, but it’s safer to use the exact
|
2012-03-27 23:13:14 +00:00
|
|
|
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.
