78 1.10 mrg <p>GCC requires that various tools and packages be available for use in the
79 1.9 mrg build procedure. Modifying GCC sources requires additional tools
80 1.9 mrg described below.

84 1.17 mrg <dt><span>ISO C++11 compiler</span></dt>
85 1.16 mrg <dd><p>Necessary to bootstrap GCC. GCC 4.8.3 or newer has sufficient
86 1.16 mrg support for used C++11 features, with earlier GCC versions you
87 1.16 mrg might run into implementation bugs.
88 1.16 mrg </p>
89 1.16 mrg <p>Versions of GCC prior to 11 also allow bootstrapping with an ISO C++98
90 1.16 mrg compiler, versions of GCC prior to 4.8 also allow bootstrapping with a
91 1.16 mrg ISO C89 compiler, and versions of GCC prior to 3.4 also allow
92 1.16 mrg bootstrapping with a traditional (K&R) C compiler.
93 1.10 mrg </p>
94 1.10 mrg <p>To build all languages in a cross-compiler or other configuration where
95 1.1 mrg 3-stage bootstrap is not performed, you need to start with an existing
96 1.16 mrg GCC binary (version 4.8.3 or later) because source code for language
97 1.1 mrg frontends other than C might use GCC extensions.
98 1.10 mrg </p>
99 1.10 mrg </dd>
100 1.17 mrg <dt><span>C standard library and headers</span></dt>
101 1.10 mrg <dd>
102 1.10 mrg <p>In order to build GCC, the C standard library and headers must be present
103 1.5 mrg for all target variants for which target libraries will be built (and not
104 1.5 mrg only the variant of the host C++ compiler).
105 1.10 mrg </p>
106 1.12 mrg <p>This affects the popular ‘<samp>x86_64-pc-linux-gnu</samp>’ platform (among
107 1.10 mrg other multilib targets), for which 64-bit (‘<samp>x86_64</samp>’) and 32-bit
108 1.10 mrg (‘<samp>i386</samp>’) libc headers are usually packaged separately. If you do a
109 1.12 mrg build of a native compiler on ‘<samp>x86_64-pc-linux-gnu</samp>’, make sure you
110 1.5 mrg either have the 32-bit libc developer package properly installed (the exact
111 1.5 mrg name of the package depends on your distro) or you must build GCC as a
112 1.5 mrg 64-bit only compiler by configuring with the option
113 1.10 mrg <samp>--disable-multilib</samp>. Otherwise, you may encounter an error such as
114 1.10 mrg ‘<samp>fatal error: gnu/stubs-32.h: No such file</samp>’

118 1.10 mrg <dd>
119 1.13 mrg <p>In order to build GNAT, the Ada compiler, you need a working GNAT
120 1.16 mrg compiler (GCC version 5.1 or later).
121 1.13 mrg </p>
122 1.13 mrg <p>This includes GNAT tools such as <code>gnatmake</code> and
123 1.13 mrg <code>gnatlink</code>, since the Ada front end is written in Ada and
124 1.13 mrg uses some GNAT-specific extensions.
125 1.13 mrg </p>
126 1.13 mrg <p>In order to build a cross compiler, it is strongly recommended to install
127 1.13 mrg the new compiler as native first, and then use it to build the cross
128 1.13 mrg compiler. Other native compiler versions may work but this is not guaranteed and
129 1.13 mrg will typically fail with hard to understand compilation errors during the
130 1.13 mrg build.
131 1.13 mrg </p>
132 1.13 mrg <p>Similarly, it is strongly recommended to use an older version of GNAT to build
133 1.13 mrg GNAT. More recent versions of GNAT than the version built are not guaranteed
134 1.13 mrg to work and will often fail during the build with compilation errors.
135 1.13 mrg </p>
136 1.13 mrg <p>Note that <code>configure</code> does not test whether the GNAT installation works
137 1.13 mrg and has a sufficiently recent version; if too old a GNAT version is
138 1.13 mrg installed and <samp>--enable-languages=ada</samp> is used, the build will fail.
139 1.13 mrg </p>
140 1.13 mrg <p><code>ADA_INCLUDE_PATH</code> and <code>ADA_OBJECT_PATH</code> environment variables
141 1.13 mrg must not be set when building the Ada compiler, the Ada tools, or the
142 1.13 mrg Ada runtime libraries. You can check that your build environment is clean
143 1.13 mrg by verifying that ‘<samp>gnatls -v</samp>’ lists only one explicit path in each
144 1.13 mrg section.
145 1.10 mrg </p>

147 1.17 mrg <dt><span><span id="GDC-prerequisite"></span>GDC</span></dt>
148 1.16 mrg <dd>
149 1.16 mrg <p>In order to build GDC, the D compiler, you need a working GDC
150 1.16 mrg compiler (GCC version 9.4 or later) and D runtime library,
151 1.16 mrg ‘<samp>libphobos</samp>’, as the D front end is written in D.
152 1.16 mrg </p>
153 1.16 mrg <p>Versions of GDC prior to 12 can be built with an ISO C++11 compiler, which can
154 1.16 mrg then be installed and used to bootstrap newer versions of the D front end.
155 1.16 mrg </p>
156 1.16 mrg <p>It is strongly recommended to use an older version of GDC to build GDC. More
157 1.16 mrg recent versions of GDC than the version built are not guaranteed to work and
158 1.16 mrg will often fail during the build with compilation errors relating to
159 1.16 mrg deprecations or removed features.
160 1.16 mrg </p>
161 1.16 mrg <p>Note that <code>configure</code> does not test whether the GDC installation works
162 1.16 mrg and has a sufficiently recent version. Though the implementation of the D
163 1.16 mrg front end does not make use of any GDC-specific extensions, or novel features
164 1.16 mrg of the D language, if too old a GDC version is installed and
165 1.16 mrg <samp>--enable-languages=d</samp> is used, the build will fail.
166 1.16 mrg </p>
167 1.16 mrg <p>On some targets, ‘<samp>libphobos</samp>’ isn’t enabled by default, but compiles
168 1.16 mrg and works if <samp>--enable-libphobos</samp> is used. Specifics are
169 1.16 mrg documented for affected targets.
170 1.16 mrg </p>

172 1.17 mrg <dt><span>A “working” POSIX compatible shell, or GNU bash</span></dt>
173 1.10 mrg <dd>
174 1.10 mrg <p>Necessary when running <code>configure</code> because some
175 1.10 mrg <code>/bin/sh</code> shells have bugs and may crash when configuring the
176 1.10 mrg target libraries. In other cases, <code>/bin/sh</code> or <code>ksh</code>
177 1.1 mrg have disastrous corner-case performance problems. This
178 1.10 mrg can cause target <code>configure</code> runs to literally take days to
179 1.1 mrg complete in some cases.
180 1.10 mrg </p>
181 1.10 mrg <p>So on some platforms <code>/bin/ksh</code> is sufficient, on others it
182 1.10 mrg isn’t. See the host/target specific instructions for your platform, or
183 1.10 mrg use <code>bash</code> to be sure. Then set <code>CONFIG_SHELL</code> in your
184 1.1 mrg environment to your “good” shell prior to running
185 1.10 mrg <code>configure</code>/<code>make</code>.
186 1.10 mrg </p>
187 1.10 mrg <p><code>zsh</code> is not a fully compliant POSIX shell and will not
188 1.1 mrg work when configuring GCC.

249 1.10 mrg <p>Several support libraries are necessary to build GCC, some are required,
250 1.3 skrll others optional. While any sufficiently new version of required tools
251 1.3 skrll usually work, library requirements are generally stricter. Newer

253 1.3 skrll versions documented. We appreciate bug reports about problems with
254 1.3 skrll newer versions, though. If your OS vendor provides packages for the
