<h1 align="center">Old installation documentation</h1>
|
| 45 |
|
|
|
| 46 |
|
|
<p>Note most of this information is out of date and superseded by the
|
| 47 |
|
|
previous chapters of this manual. It is provided for historical
|
| 48 |
|
|
reference only, because of a lack of volunteers to merge it into the
|
| 49 |
|
|
main manual.
|
| 50 |
|
|
|
| 51 |
|
|
<p>Here is the procedure for installing GCC on a GNU or Unix system.
|
| 52 |
|
|
|
| 53 |
|
|
<ol type=1 start=1>
|
| 54 |
|
|
<li>If you have chosen a configuration for GCC which requires other GNU
|
| 55 |
|
|
tools (such as GAS or the GNU linker) instead of the standard system
|
| 56 |
|
|
tools, install the required tools in the build directory under the names
|
| 57 |
|
|
<samp><span class="file">as</span></samp>, <samp><span class="file">ld</span></samp> or whatever is appropriate.
|
| 58 |
|
|
|
| 59 |
|
|
<p>Alternatively, you can do subsequent compilation using a value of the
|
| 60 |
|
|
<code>PATH</code> environment variable such that the necessary GNU tools come
|
| 61 |
|
|
before the standard system tools.
|
| 62 |
|
|
|
| 63 |
|
|
<li>Specify the host, build and target machine configurations. You do this
|
| 64 |
|
|
when you run the <samp><span class="file">configure</span></samp> script.
|
| 65 |
|
|
|
| 66 |
|
|
<p>The <dfn>build</dfn> machine is the system which you are using, the
|
| 67 |
|
|
<dfn>host</dfn> machine is the system where you want to run the resulting
|
| 68 |
|
|
compiler (normally the build machine), and the <dfn>target</dfn> machine is
|
| 69 |
|
|
the system for which you want the compiler to generate code.
|
| 70 |
|
|
|
| 71 |
|
|
<p>If you are building a compiler to produce code for the machine it runs
|
| 72 |
|
|
on (a native compiler), you normally do not need to specify any operands
|
| 73 |
|
|
to <samp><span class="file">configure</span></samp>; it will try to guess the type of machine you are on
|
| 74 |
|
|
and use that as the build, host and target machines. So you don't need
|
| 75 |
|
|
to specify a configuration when building a native compiler unless
|
| 76 |
|
|
<samp><span class="file">configure</span></samp> cannot figure out what your configuration is or guesses
|
| 77 |
|
|
wrong.
|
| 78 |
|
|
|
| 79 |
|
|
<p>In those cases, specify the build machine's <dfn>configuration name</dfn>
|
| 80 |
|
|
with the <samp><span class="option">--host</span></samp> option; the host and target will default to be
|
| 81 |
|
|
the same as the host machine.
|
| 82 |
|
|
|
| 83 |
|
|
<p>Here is an example:
|
| 84 |
|
|
|
| 85 |
|
|
<pre class="smallexample"> ./configure --host=sparc-sun-sunos4.1
|
| 86 |
|
|
</pre>
|
| 87 |
|
|
<p>A configuration name may be canonical or it may be more or less
|
| 88 |
|
|
abbreviated.
|
| 89 |
|
|
|
| 90 |
|
|
<p>A canonical configuration name has three parts, separated by dashes.
|
| 91 |
|
|
It looks like this: `<samp><var>cpu</var><span class="samp">-</span><var>company</var><span class="samp">-</span><var>system</var></samp>'.
|
| 92 |
|
|
(The three parts may themselves contain dashes; <samp><span class="file">configure</span></samp>
|
| 93 |
|
|
can figure out which dashes serve which purpose.) For example,
|
| 94 |
|
|
`<samp><span class="samp">m68k-sun-sunos4.1</span></samp>' specifies a Sun 3.
|
| 95 |
|
|
|
| 96 |
|
|
<p>You can also replace parts of the configuration by nicknames or aliases.
|
| 97 |
|
|
For example, `<samp><span class="samp">sun3</span></samp>' stands for `<samp><span class="samp">m68k-sun</span></samp>', so
|
| 98 |
|
|
`<samp><span class="samp">sun3-sunos4.1</span></samp>' is another way to specify a Sun 3.
|
| 99 |
|
|
|
| 100 |
|
|
<p>You can specify a version number after any of the system types, and some
|
| 101 |
|
|
of the CPU types. In most cases, the version is irrelevant, and will be
|
| 102 |
|
|
ignored. So you might as well specify the version if you know it.
|
| 103 |
|
|
|
| 104 |
|
|
<p>See <a href="#Configurations">Configurations</a>, for a list of supported configuration names and
|
| 105 |
|
|
notes on many of the configurations. You should check the notes in that
|
| 106 |
|
|
section before proceeding any further with the installation of GCC.

</blockquote>
|
| 121 |
|
|
|
| 122 |
|
|
<p>Here are the recognized company names. As you can see, customary
|
| 123 |
|
|
abbreviations are used rather than the longer official names.
|

|
<!-- What should be done about merlin, tek*, dolphin? -->
|
| 126 |

|
| 133 |
|
|
|
| 134 |
|
|
<p>The company name is meaningful only to disambiguate when the rest of
|
| 135 |
|
|
the information supplied is insufficient. You can omit it, writing
|
| 136 |
|
|
just `<samp><var>cpu</var><span class="samp">-</span><var>system</var></samp>', if it is not needed. For example,
|
| 137 |
|
|
`<samp><span class="samp">vax-ultrix4.2</span></samp>' is equivalent to `<samp><span class="samp">vax-dec-ultrix4.2</span></samp>'.
|
| 138 |
|
|
|
| 139 |
|
|
<p>Here is a list of system types:
|
| 140 |
|
|
|
| 141 |
|
|
<blockquote>
|
| 142 |
|
|
386bsd, aix, acis, amigaos, aos, aout, aux, bosx, bsd, clix, coff, ctix, cxux,
|
| 143 |
|
|
dgux, dynix, ebmon, ecoff, elf, esix, freebsd, hms, genix, gnu, linux,

|
|
vxworks, winnt, xenix.
|
| 148 |
|
|
</blockquote>
|
| 149 |
|
|
|
| 150 |
|
|
<p class="noindent">You can omit the system type; then <samp><span class="file">configure</span></samp> guesses the
|
| 151 |
|
|
operating system from the CPU and company.
|
| 152 |
|
|
|
| 153 |
|
|
<p>You can add a version number to the system type; this may or may not
|
| 154 |
|
|
make a difference. For example, you can write `<samp><span class="samp">bsd4.3</span></samp>' or
|
| 155 |
|
|
`<samp><span class="samp">bsd4.4</span></samp>' to distinguish versions of BSD. In practice, the version
|
| 156 |
|
|
number is most needed for `<samp><span class="samp">sysv3</span></samp>' and `<samp><span class="samp">sysv4</span></samp>', which are often
|
| 157 |
|
|
treated differently.
|
| 158 |
|
|
|
| 159 |
|
|
<p>`<samp><span class="samp">linux-gnu</span></samp>' is the canonical name for the GNU/Linux target; however
|
| 160 |
|
|
GCC will also accept `<samp><span class="samp">linux</span></samp>'. The version of the kernel in use is
|
| 161 |
|
|
not relevant on these systems. A suffix such as `<samp><span class="samp">libc1</span></samp>' or `<samp><span class="samp">aout</span></samp>'
|
| 162 |
|
|
distinguishes major versions of the C library; all of the suffixed versions
|
| 163 |
|
|
are obsolete.
|
| 164 |
|
|
|
| 165 |
|
|
<p>If you specify an impossible combination such as `<samp><span class="samp">i860-dg-vms</span></samp>',
|
| 166 |
|
|
then you may get an error message from <samp><span class="file">configure</span></samp>, or it may
|
| 167 |
|
|
ignore part of the information and do the best it can with the rest.
|
| 168 |
|
|
<samp><span class="file">configure</span></samp> always prints the canonical name for the alternative
|
| 169 |
|
|
that it used. GCC does not support all possible alternatives.
|
| 170 |
|
|
|
| 171 |
|
|
<p>Often a particular model of machine has a name. Many machine names are
|
| 172 |
|
|
recognized as aliases for CPU/company combinations. Thus, the machine
|
| 173 |
|
|
name `<samp><span class="samp">sun3</span></samp>', mentioned above, is an alias for `<samp><span class="samp">m68k-sun</span></samp>'.
|
| 174 |
|
|
Sometimes we accept a company name as a machine name, when the name is
|
| 175 |
|
|
popularly used for a particular machine. Here is a table of the known
|
| 176 |
|
|
machine names:
|
| 177 |
|
|
|
| 178 |
|
|

|
| 192 |
|
|
|
| 193 |
|
|
<p class="noindent">Remember that a machine name specifies both the cpu type and the company
|
| 194 |
|
|
name.
|
| 195 |
|
|
If you want to install your own homemade configuration files, you can
|
| 196 |
|
|
use `<samp><span class="samp">local</span></samp>' as the company name to access them. If you use
|
| 197 |
|
|
configuration `<samp><var>cpu</var><span class="samp">-local</span></samp>', the configuration name
|
| 198 |
|
|
without the cpu prefix
|
| 199 |
|
|
is used to form the configuration file names.
|
| 200 |
|
|
|
| 201 |
|
|
<p>Thus, if you specify `<samp><span class="samp">m68k-local</span></samp>', configuration uses
|
| 202 |
|
|
files <samp><span class="file">m68k.md</span></samp>, <samp><span class="file">local.h</span></samp>, <samp><span class="file">m68k.c</span></samp>,
|
| 203 |
|
|
<samp><span class="file">xm-local.h</span></samp>, <samp><span class="file">t-local</span></samp>, and <samp><span class="file">x-local</span></samp>, all in the
|
| 204 |
|
|
directory <samp><span class="file">config/m68k</span></samp>.
