It is provided for historical +reference only, because of a lack of volunteers to merge it into the +main manual. + + <p>Here is the procedure for installing GCC on a GNU or Unix system. + + <ol type=1 start=1> +<li>If you have chosen a configuration for GCC which requires other GNU +tools (such as GAS or the GNU linker) instead of the standard system +tools, install the required tools in the build directory under the names +<samp><span class="file">as</span></samp>, <samp><span class="file">ld</span></samp> or whatever is appropriate. + + <p>Alternatively, you can do subsequent compilation using a value of the +<code>PATH</code> environment variable such that the necessary GNU tools come +before the standard system tools. + + <li>Specify the host, build and target machine configurations. You do this +when you run the <samp><span class="file">configure</span></samp> script. + + <p>The <dfn>build</dfn> machine is the system which you are using, the +<dfn>host</dfn> machine is the system where you want to run the resulting +compiler (normally the build machine), and the <dfn>target</dfn> machine is +the system for which you want the compiler to generate code. + + <p>If you are building a compiler to produce code for the machine it runs +on (a native compiler), you normally do not need to specify any operands +to <samp><span class="file">configure</span></samp>; it will try to guess the type of machine you are on +and use that as the build, host and target machines. So you don't need +to specify a configuration when building a native compiler unless +<samp><span class="file">configure</span></samp> cannot figure out what your configuration is or guesses +wrong. + + <p>In those cases, specify the build machine's <dfn>configuration name</dfn> +with the <samp><span class="option">--host</span></samp> option; the host and target will default to be +the same as the host machine. + + <p>Here is an example: + + <pre class="smallexample"> ./configure --host=sparc-sun-sunos4.1 +</pre> + <p>A configuration name may be canonical or it may be more or less +abbreviated. + + <p>A canonical configuration name has three parts, separated by dashes. +It looks like this: ‘<samp><var>cpu</var><span class="samp">-</span><var>company</var><span class="samp">-</span><var>system</var></samp>’. +(The three parts may themselves contain dashes; <samp><span class="file">configure</span></samp> +can figure out which dashes serve which purpose.) For example, +‘<samp><span class="samp">m68k-sun-sunos4.1</span></samp>’ specifies a Sun 3. + + <p>You can also replace parts of the configuration by nicknames or aliases. +For example, ‘<samp><span class="samp">sun3</span></samp>’ stands for ‘<samp><span class="samp">m68k-sun</span></samp>’, so +‘<samp><span class="samp">sun3-sunos4.1</span></samp>’ is another way to specify a Sun 3. + + <p>You can specify a version number after any of the system types, and some +of the CPU types. In most cases, the version is irrelevant, and will be +ignored. So you might as well specify the version if you know it. + + <p>See <a href="#Configurations">Configurations</a>, for a list of supported configuration names and +notes on many of the configurations. You should check the notes in that +section before proceeding any further with the installation of GCC. + + </ol> + + <p><h2><a name="Configurations"></a>Configurations Supported by GCC</h2><a name="index-configurations-supported-by-GCC-1"></a> +Here are the possible CPU types: + + <blockquote> +<!-- gmicro, fx80, spur and tahoe omitted since they don't work. --> +1750a, a29k, alpha, arm, avr, c<var>n</var>, clipper, dsp16xx, elxsi, fr30, h8300, +hppa1.0, hppa1.1, i370, i386, i486, i586, i686, i786, i860, i960, ip2k, m32r, +m68000, m68k, m6811, m6812, m88k, mcore, mips, mipsel, mips64, mips64el, +mn10200, mn10300, ns32k, pdp11, powerpc, powerpcle, romp, rs6000, sh, sparc, +sparclite, sparc64, v850, vax, we32k. +</blockquote> + + <p>Here are the recognized company names. As you can see, customary +abbreviations are used rather than the longer official names. + +<!-- What should be done about merlin, tek*, dolphin? --> + <blockquote> +acorn, alliant, altos, apollo, apple, att, bull, +cbm, convergent, convex, crds, dec, dg, dolphin, +elxsi, encore, harris, hitachi, hp, ibm, intergraph, isi, +mips, motorola, ncr, next, ns, omron, plexus, +sequent, sgi, sony, sun, tti, unicom, wrs. +</blockquote> + + <p>The company name is meaningful only to disambiguate when the rest of +the information supplied is insufficient. You can omit it, writing +just ‘<samp><var>cpu</var><span class="samp">-</span><var>system</var></samp>’, if it is not needed. For example, +‘<samp><span class="samp">vax-ultrix4.2</span></samp>’ is equivalent to ‘<samp><span class="samp">vax-dec-ultrix4.2</span></samp>’. + + <p>Here is a list of system types: + + <blockquote> +386bsd, aix, acis, amigaos, aos, aout, aux, bosx, bsd, clix, coff, ctix, cxux, +dgux, dynix, ebmon, ecoff, elf, esix, freebsd, hms, genix, gnu, linux, +linux-gnu, hiux, hpux, iris, irix, isc, luna, lynxos, mach, minix, msdos, mvs, +netbsd, newsos, nindy, ns, osf, osfrose, ptx, riscix, riscos, rtu, sco, sim, +solaris, sunos, sym, sysv, udi, ultrix, unicos, uniplus, unos, vms, vsta, +vxworks, winnt, xenix. +</blockquote> + +<p class="noindent">You can omit the system type; then <samp><span class="file">configure</span></samp> guesses the +operating system from the CPU and company. + + <p>You can add a version number to the system type; this may or may not +make a difference. For example, you can write ‘<samp><span class="samp">bsd4.3</span></samp>’ or +‘<samp><span class="samp">bsd4.4</span></samp>’ to distinguish versions of BSD. In practice, the version +number is most needed for ‘<samp><span class="samp">sysv3</span></samp>’ and ‘<samp><span class="samp">sysv4</span></samp>’, which are often +treated differently. + + <p>‘<samp><span class="samp">linux-gnu</span></samp>’ is the canonical name for the GNU/Linux target; however +GCC will also accept ‘<samp><span class="samp">linux</span></samp>’. The version of the kernel in use is +not relevant on these systems. A suffix such as ‘<samp><span class="samp">libc1</span></samp>’ or ‘<samp><span class="samp">aout</span></samp>’ +distinguishes major versions of the C library; all of the suffixed versions +are obsolete. + + <p>If you specify an impossible combination such as ‘<samp><span class="samp">i860-dg-vms</span></samp>’, +then you may get an error message from <samp><span class="file">configure</span></samp>, or it may +ignore part of the information and do the best it can with the rest. +<samp><span class="file">configure</span></samp> always prints the canonical name for the alternative +that it used. GCC does not support all possible alternatives. + + <p>Often a particular model of machine has a name. Many machine names are +recognized as aliases for CPU/company combinations. Thus, the machine +name ‘<samp><span class="samp">sun3</span></samp>’, mentioned above, is an alias for ‘<samp><span class="samp">m68k-sun</span></samp>’. +Sometimes we accept a company name as a machine name, when the name is +popularly used for a particular machine. Here is a table of the known +machine names: + + <blockquote> +3300, 3b1, 3b<var>n</var>, 7300, altos3068, altos, +apollo68, att-7300, balance, +convex-c<var>n</var>, crds, decstation-3100, +decstation, delta, encore, +fx2800, gmicro, hp7<var>nn</var>, hp8<var>nn</var>, +hp9k2<var>nn</var>, hp9k3<var>nn</var>, hp9k7<var>nn</var>, +hp9k8<var>nn</var>, iris4d, iris, isi68, +m3230, magnum, merlin, miniframe, +mmax, news-3600, news800, news, next, +pbd, pc532, pmax, powerpc, powerpcle, ps2, risc-news, +rtpc, sun2, sun386i, sun386, sun3, +sun4, symmetry, tower-32, tower. +</blockquote> + +<p class="noindent">Remember that a machine name specifies both the cpu type and the company +name. +If you want to install your own homemade configuration files, you can +use ‘<samp><span class="samp">local</span></samp>’ as the company name to access them. If you use +configuration ‘<samp><var>cpu</var><span class="samp">-local</span></samp>’, the configuration name +without the cpu prefix +is used to form the configuration file names. + + <p>Thus, if you specify ‘<samp><span class="samp">m68k-local</span></samp>’, configuration uses +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>, +<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 +directory <samp><span class="file">config/m68k</span></samp>. +<hr /> +<p><a href="./index.html">Return to the GCC Installation page</a> + +<!-- ***GFDL******************************************************************** --> +<!-- *************************************************************************** --> +<!-- Part 6 The End of the Document --> +</body></html> + |
