| 4 | <para>This chapter attempts to install a complete Gnome-&gnome-version; desktop
|
|---|
| 5 | environment and a limited Gnome 1.4 library environment that is
|
|---|
| 6 | sufficient to run Gnome 1.4 applications included in this book. The
|
|---|
| 7 | order of the pages are meant to follow the build order defined by the
|
|---|
| 8 | Gnome development team as published in the <ulink
|
|---|
| 9 | url="http://www.gnome.org/start/&gnome-version;/notes/rninstallation.html">release notes</ulink>, with two exceptions. If a package is in the release notes build list, but not in this chapter, it has been installed elsewhere in the book.</para>
|

|
|---|
| 11 | <para>The installation of Gnome-&gnome-version; is a large undertaking and one we would
|
|---|
| 12 | like to see you complete with the least amount of stress. One
|
|---|
| 13 | of our first goals in this installation is to protect your previously
|
|---|
| 14 | installed software, especially if you are testing Gnome on your machine.
|
|---|
| 15 | Gnome-&gnome-version; packages utilize the --prefix= option for configure, so we will
|
|---|
| 16 | use that and an Environment variable (<envar>GNOME_PREFIX</envar>) to add flexibility to
|
|---|
| 17 | the install.</para>
|
|---|
| 18 |
|
|---|
| 19 | <para>If you know that you want Gnome as your desktop, it is recommended that
|
|---|
| 20 | you install with --prefix=/usr. If you are not sure that you are going
|
|---|
| 21 | to keep Gnome on your installation, it is recommended that you install with
|
|---|
| 22 | --prefix=/opt/gnome-&gnome-version;. Setting the Environment variable and the
|
|---|
| 23 | additional edits required by the second option are covered on the
|
|---|
| 24 | pre-installation page.</para>
|
|---|
| 25 |
|
|---|
| 26 | <para>If you choose the second option, removal of Gnome-2.2 is as easy as removing the edits from the pre-installation page and issue the following command:
|
|---|
| 27 | <screen><userinput>rm /opt/gnome-&gnome-version; -r </userinput></screen></para>
|
|---|
| 28 |
|
|---|
| 29 | <para>If your system was completely built per LFS and BLFS
|
|---|
| 30 | instructions, you have a very good chance of using Gnome-&gnome-version;
|
|---|
| 31 | after your first install. If you are a typical LFS user, you have made
|
|---|
| 32 | modifications to the instructions along the way knowing that you have to
|
|---|
| 33 | take those modifications into account on future installations. You
|
|---|
| 34 | should have no problems integrating Gnome-&gnome-version; into your unique setup, but
|
|---|
| 35 | you will have 28 to 33 packages installed before you can run Gnome
|
|---|
| 36 | through any testing (assuming your window manager is preinstalled and
|
|---|
| 37 | tested). We would anticipate that you will be rebuilding gnome at least
|
|---|
| 38 | once to make adjustments for your setup.</para>
|
|---|
| 39 |
|
|---|
| 40 | <para>If you are building a Gnome 1.4 desktop environment, you would
|
|---|
| 41 | install only those libraries in the Gnome 1.4 chapter <emphasis>and</emphasis> any dependencies listed on those pages whether labeled or not. Gnome packages without pages are simply installed with:
|
|---|
| 42 | <screen><userinput>./configure --prefix=/opt/gnome &&
|
|---|
| 43 | make &&
|
|---|
| 44 | make install</userinput></screen>
|
|---|
| 45 | These instructions are simplistic to facilitate removal of Gnome 1.4
|
|---|
| 46 | from BLFS systems when it is no longer necessary. These instructions
|
|---|
| 47 | may be refined later to comply with BLFS standards for file locations,
|
|---|
| 48 | specifically <filename class='directory'>/opt/gnome/etc</filename> to
|
|---|
| 49 | <filename class='directory'>/etc</filename> and <filename
|
|---|
| 50 | class='directory'>/opt/gnome/var</filename> to
|
|---|
| 51 | <filename class='directory'>/var</filename>. You should consider using the Gnome 1.4 hint
|
|---|
| 52 | located at <ulink url="http://hints.linuxfromscratch.org/hints"/> if you
|
|---|
| 53 | have no interest in Gnome-&gnome-version;.</para>
|

|

|
