19    
20     <p>
21 swift 1.24 If you have booted from a Gentoo LiveCD, you are able to use <c>mirrorselect</c>
22 swift 1.2 to update <path>/etc/make.conf</path> so fast mirrors are used for both Portage
23 swift 1.57 and source code (of course this requires a working network connection):

30     <p>
31     If for some reason <c>mirrorselect</c> fails, don't panic. This step is
32 swift 1.33 completely optional, the default values suffice.

41     <p>
42 swift 1.24 One thing still remains to be done before we enter the new environment and that
43     is copying over the DNS information in <path>/etc/resolv.conf</path>. You need
44 swift 1.5 to do this to ensure that networking still works even after entering the new
45     environment. <path>/etc/resolv.conf</path> contains the nameservers for your
46     network.

74 swift 1.1 <body>
75    
76     <p>
77 swift 1.19 Now that all partitions are initialized and the base environment
78 swift 1.1 installed, it is time to enter our new installation environment by
79 swift 1.9 <e>chrooting</e> into it. This means that we change from the current
80 swift 1.2 installation environment (LiveCD or other installation medium) to your
81 swift 1.19 installation system (namely the initialized partitions).
82 swift 1.1 </p>
83    
84     <p>
85     This chrooting is done in three steps. First we will change the root
86 swift 1.2 from <path>/</path> (on the installation medium) to <path>/mnt/gentoo</path>
87     (on your partitions) using <c>chroot</c>. Then we will create a new environment
88     using <c>env-update</c>, which essentially creates environment variables.
89 swift 1.1 Finally, we load those variables into memory using <c>source</c>.
90     </p>

100     Congratulations! You are now inside your own Gentoo Linux environment.
101 swift 1.10 Of course it is far from finished, which is why the installation still
102 swift 1.1 has some sections left :-)

108 swift 1.64 <title>Updating the Portage tree</title>
109 swift 1.2 <body>
110    
111     <p>
112 swift 1.64 If you have a working Internet connection and you don't want to install our
113 neysx 1.65 prebuilt packages later on (also known as GRP packages), you should update your
114     Portage tree to the latest version. <c>emerge --sync</c> does this for you.
115     Other users should <e>only</e> run <c>emerge --metadata</c> to create the cache
116     database Portage usually creates after <c>emerge --sync</c>.
117 swift 1.2 </p>
118

125 swift 1.13 </pre>
126    
127     <p>
128     If you are warned that a new Portage version is available and that you should
129 swift 1.34 update Portage, you should ignore it. Portage will be updated for you later
130 bennyc 1.16 on during the installation.
131 swift 1.13 </p>

134     </subsection>
135 swift 1.28 <subsection id="configure_USE">
136 swift 1.21 <title>Configuring the USE variable</title>
137     <body>
138    
139 swift 1.57 <warn>
140     Do not make any modifications to the USE variable if you are performing a stage3
141     with GRP installation. You can alter the USE variable after having installed the
142     packages you want. Gremlins are known to attack your system if you ignore this
143     warning!
144     </warn>
145    
146 swift 1.21 <p>
147     <c>USE</c> is one of the most powerful variables Gentoo provides to its users.
148     Several programs can be compiled with or without optional support for certain
149     items. For instance, some programs can be compiled with gtk-support, or with
150     qt-support. Others can be compiled with or without SSL support. Some programs
151     can even be compiled with framebuffer support (svgalib) instead of X11 support
152     (X-server).
153     </p>
154    
155     <p>
156     Most distributions compile their packages with support for as much as possible,
157     increasing the size of the programs and startup time, not to mention an enormous
158 swift 1.24 amount of dependencies. With Gentoo you can define what options a package
159 swift 1.21 should be compiled with. This is where <c>USE</c> comes into play.
160     </p>
161    
162     <p>
163     In the <c>USE</c> variable you define keywords which are mapped onto
164     compile-options. For instance, <e>ssl</e> will compile ssl-support in the
165     programs that support it. <e>-X</e> will remove X-server support (note the minus
166     sign in front). <e>gnome gtk -kde -qt</e> will compile your programs with gnome
167     (and gtk) support, and not with kde (and qt) support, making your system fully
168     tweaked for GNOME.
169     </p>
170    
171     <p>
172     The default <c>USE</c> settings are placed in
173     <path>/etc/make.profile/make.defaults</path>. What you place in
174     <path>/etc/make.conf</path> is calculated against these defaults settings. If
175     you add something to the <c>USE</c> setting, it is added to the default list. If
176     you remove something from the <c>USE</c> setting (by placing a minus sign in
177     front of it) it is removed from the default list (if it was in the default list
178     at all). <e>Never</e> alter anything inside the <path>/etc/make.profile</path>
179     directory; it gets overwritten when you update Portage!
180     </p>
181    
182     <p>
183     A full description on <c>USE</c> can be found in the second part of the Gentoo
184 neysx 1.52 Handbook, <uri link="?part=2&amp;chap=2">USE flags</uri>. A full description on
185     the available USE flags can be found on your system in
186 swift 1.23 <path>/usr/portage/profiles/use.desc</path>.
187     </p>

192 swift 1.23 </pre>
193    
194     <p>
195     As an example we show a <c>USE</c> setting for a KDE-based system with DVD, ALSA
196     and CD Recording support:

198    
199     <pre caption="Opening /etc/make.conf">

205     </pre>
206    
207 dertobi123 1.53 <p>
208     You will probably only use one or maybe two locales on your system. Up until now
209 swift 1.55 after compiling <c>glibc</c> a full set of all available locales will be
210     created. As of now you can activate the <c>userlocales</c> USE flag and specify
211 dertobi123 1.53 only the locales you will need in <path>/etc/locales.build</path>.

239    
240     <p>
241     If you are interested in using a collection of systems to help in compiling your
242     system you might want to take a look at our <uri
243     link="/doc/en/distcc.xml">DistCC Guide</uri>. By using <c>distcc</c> you can use
244     the processing power of several systems to aid you with the installation.

254     <p>
255     Now take a seat and think of your previous steps. We asked you to
256     select a <e>stage1</e>, <e>stage2</e> or <e>stage3</e> and warned you
257     that your choice is important for further installation steps. Well, this
258 neysx 1.48 is the first place where your choice defines the subsequent steps.

260    
261     <ul>
262     <li>
263 swift 1.4 If you chose <e>stage1</e>, then you have to follow <e>both</e> steps in

271 swift 1.1 </li>
272     <li>
273 swift 1.4 If you chose <e>stage3</e> (either with or without GRP) then you can skip both

284     <title>Introduction to Bootstrapping</title>
285     <body>
286    
287     <p>
288     So, you want to compile everything from scratch? Okay then :-)
289     </p>
290    
291     <p>
292     In this step, we will <e>bootstrap</e> your Gentoo system. This takes a
293     long time, but the result is a system that has been optimized from the
294     ground up for your specific machine and needs.
295     </p>
296    
297     <p>
298     <e>Bootstrapping</e> means building the GNU C Library, GNU Compiler
299 swift 1.32 Collection and several other key system programs.
300 swift 1.1 </p>
301    
302     <p>
303 swift 1.62 Before starting the bootstrap, you might want to download all necessary
304     sourcecode first. If you do not want to do this, continue
305     with <uri link="#bootstrap">Bootstrapping the System</uri>.

310     <subsection>
311 swift 1.1 <title>Optional: Downloading the Sources First</title>
312     <body>
313    
314     <p>
315 swift 1.25 If you haven't copied over all source code before, then the bootstrap
316 swift 1.1 script will download all necessary files. It goes without saying that
317     this only works if you have a working network connnection :-) If you want to
318 swift 1.25 download the source code first and later bootstrap the system (for instance
319 swift 1.1 because you don't want to have your internet connection open during the
320     compilation) use the <e>-f</e> option of the bootstrap script, which will
321 swift 1.25 fetch (hence the letter <e>f</e>) all source code for you.
322 swift 1.1 </p>
323    
324     <pre caption = "Downloading the necessary sources">

336     Okay then, take your keyboard and punch in the next commands to start
337 swift 1.36 the bootstrap. Then go amuse yourself with something else because this step
338     takes quite some time to finish.

346     <p>
347 swift 1.63 When you have set the <c>nptl</c> USE flag, rerunning <c>bootstrap.sh</c> might
348     fail with a message that <c>linux-headers</c> blocks <c>linux26-headers</c>.
349     When you receive this error, remove <c>linux-headers</c> and retry:

377    
378     <p>
379     <e>All</e> system packages? No, not really. In this step, you will build
380 swift 1.19 the system packages of which there are no alternatives to use.
381     Some system packages have several alternatives (such as system loggers)
382 swift 1.1 and as Gentoo is all about choices, we don't want to force one upon you.
