<title>Installation of Grub</title>

<para>This package is known to behave badly when you have changed its default
optimization flags (including the -march and -mcpu options). Therefore, if you
have defined any environment variables that override default optimizations,
such as CFLAGS and CXXFLAGS, we recommend unsetting them when building
Grub.</para>

<para>First fix a compilation problem with GCC-&gcc-version;:</para>

<screen><userinput>patch -Np1 -i ../&grub-patch;</userinput></screen>

<para>Now prepare Grub for compilation:</para>

<screen><userinput>./configure --prefix=/usr</userinput></screen>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>And install it:</para>

<screen><userinput>make install
mkdir /boot/grub
cp /usr/share/grub/i386-pc/stage{1,2} /boot/grub</userinput></screen>

<para>Replace <filename class="directory">i386-pc</filename> with whatever
directory is appropriate for your hardware.</para>

<para>The <filename class="directory">i386-pc</filename> directory also
contains a number of <filename>*stage1_5</filename> files, different ones
for different filesystems. Have a look at the ones available and copy the
appropriate ones to the <filename class="directory">/boot/grub</filename>
directory. Most people will copy the <filename>e2fs_stage1_5</filename>
and/or <filename>reiserfs_stage1_5</filename> files.</para>
