9 | <p>N<p>ow that GCC has been built (and optionally tested), you can install it with
|
---|
10 | <pre>cd <var>objdir</var>; make install
|
---|
11 | </pre>
|
---|
12 |
|
---|
13 | <p>We strongly recommend to install into a target directory where there is
|
---|
14 | no previous version of GCC present.
|
---|
15 |
|
---|
16 | <p>That step completes the installation of GCC; user level binaries can
|
---|
17 | be found in <code><var>prefix</var>/bin</code> where <var>prefix</var> is the value you
|
---|
18 | specified with the <code>--prefix</code> to configure (or <code>/usr/local</code>
|
---|
19 | by default). (If you specified <code>--bindir</code>, that directory will
|
---|
20 | be used instead; otherwise, if you specified <code>--exec-prefix</code>,
|
---|
21 | <code><var>exec-prefix</var>/bin</code> will be used.) Headers for the C++ and
|
---|
22 | Java libraries are installed in <code><var>prefix</var>/include</code>; libraries
|
---|
23 | in <code><var>libdir</var></code> (normally <code><var>prefix</var>/lib</code>); internal
|
---|
24 | parts of the compiler in <code><var>libdir</var>/gcc-lib</code>; documentation in
|
---|
25 | info format in <code><var>infodir</var></code> (normally <code><var>prefix</var>/info</code>).
|
---|
26 |
|
---|
27 | <p>When installing cross-compilers, GCC's executables
|
---|
28 | are not only installed into <code><var>bindir</var></code>, that
|
---|
29 | is, <code><var>exec-prefix</var>/bin</code>, but additionally into
|
---|
30 | <code><var>exec-prefix</var>/<var>target-alias</var>/bin</code>, if that directory
|
---|
31 | exists. Typically, such <dfn>tooldirs</dfn> hold target-specific
|
---|
32 | binutils, including assembler and linker.
|
---|
33 |
|
---|
34 | <p>Installation into a temporary staging area or into a <code>chroot</code>
|
---|
35 | jail can be achieved with the command
|
---|
36 |
|
---|
37 | <pre>make DESTDIR=<var>path-to-rootdir</var> install
|
---|
38 | </pre>
|
---|
39 |
|
---|
40 | <p>where <var>path-to-rootdir</var> is the absolute path of
|
---|
41 | a directory relative to which all installation paths will be
|
---|
42 | interpreted. Note that the directory specified by <code>DESTDIR</code>
|
---|
43 | need not exist yet; it will be created if necessary.
|
---|
44 |
|
---|
45 | <p>There is a subtle point with tooldirs and <code>DESTDIR</code>:
|
---|
46 | If you relocate a cross-compiler installation with
|
---|
47 | e.g. <code>DESTDIR=<var>rootdir</var></code>, then the directory
|
---|
48 | <code><var>rootdir</var>/<var>exec-prefix</var>/<var>target-alias</var>/bin</code> will
|
---|
49 | be filled with duplicated GCC executables only if it already exists,
|
---|
50 | it will not be created otherwise. This is regarded as a feature,
|
---|
51 | not as a bug, because it gives slightly more control to the packagers
|
---|
52 | using the <code>DESTDIR</code> feature.
|
---|
53 |
|
---|
54 | <p>If you built a released version of GCC using <code>make bootstrap</code> then please
|
---|
55 | quickly review the build status page for your release, available from
|
---|
56 | <a href="http://gcc.gnu.org/buildstat.html">http://gcc.gnu.org/buildstat.html</a>.
|
---|
57 | If your system is not listed for the version of GCC that you built,
|
---|
58 | send a note to
|
---|
59 | <a href="mailto:gcc@gcc.gnu.org">gcc@gcc.gnu.org</a> indicating
|
---|
60 | that you successfully built and installed GCC.
|
---|
61 | Include the following information:
|
---|
62 |
|
---|
63 | <ul>
|
---|
64 | <li>Output from running <code><var>srcdir</var>/config.guess</code>. Do not send us
|
---|
65 | that file itself, just the one-line output from running it.
|
---|
66 |
|
---|
67 | <li>The output of <code>gcc -v</code> for your newly installed gcc.
|
---|
68 | This tells us which version of GCC you built and the options you passed to
|
---|
69 | configure.
|
---|
70 |
|
---|
71 | <li>Whether you enabled all languages or a subset of them. If you used a
|
---|
72 | full distribution then this information is part of the configure
|
---|
73 | options in the output of <code>gcc -v</code>, but if you downloaded the
|
---|
74 | "core" compiler plus additional front ends then it isn't apparent
|
---|
75 | which ones you built unless you tell us about it.
|
---|
76 |
|
---|
77 | <li>If the build was for GNU/Linux, also include:
|
---|
78 | <ul>
|
---|
79 | <li>The distribution name and version (e.g., Red Hat 7.1 or Debian 2.2.3);
|
---|
80 | this information should be available from <code>/etc/issue</code>.
|
---|
81 |
|
---|
82 | <li>The version of the Linux kernel, available from <code>uname --version</code>
|
---|
83 | or <code>uname -a</code>.
|
---|
84 |
|
---|
85 | <li>The version of glibc you used; for RPM-based systems like Red Hat,
|
---|
86 | Mandrake, and SuSE type <code>rpm -q glibc</code> to get the glibc version,
|
---|
87 | and on systems like Debian and Progeny use <code>dpkg -l libc6</code>.
|
---|
88 | </ul>
|
---|
89 | For other systems, you can include similar information if you think it is
|
---|
90 | relevant.
|
---|
91 |
|
---|
92 | <li>Any other information that you think would be useful to people building
|
---|
93 | GCC on the same configuration. The new entry in the build status list
|
---|
94 | will include a link to the archived copy of your message.
|
---|
95 | </ul>
|
---|
96 |
|
---|
97 | <p>We'd also like to know if the
|
---|
98 | <a href="specific.html">host/target specific installation notes</a>
|
---|
99 | didn't include your host/target information or if that information is
|
---|
100 | incomplete or out of date. Send a note to
|
---|
101 | <a href="mailto:gcc@gcc.gnu.org">gcc@gcc.gnu.org</a> telling us how the information should be changed.
|
---|
102 |
|
---|
103 | <p>If you find a bug, please report it following our
|
---|
104 | <a href="../bugs.html">bug reporting guidelines</a>.
|
---|
105 |
|
---|
106 | <p>If you want to print the GCC manuals, do <code>cd <var>objdir</var>; make
|
---|
107 | dvi</code>. You will need to have <code>texi2dvi</code> (version at least 4.1)
|
---|
108 | and TeX installed. This creates a number of <code>.dvi</code> files in
|
---|
109 | subdirectories of <code><var>objdir</var></code>; these may be converted for
|
---|
110 | printing with programs such as <code>dvips</code>. You can also
|
---|
111 | <a href="http://www.gnu.org/order/order.html">buy printed manuals from the Free Software Foundation</a>, though such manuals may not be for the most
|
---|
112 | recent version of GCC.
