<para>This package is known to have issues when its default
optimization flags (including the <parameter>-march</parameter> and
<parameter>-mcpu</parameter> options) are changed. If any environment
variables that override default optimizations have been defined, such
as <envar>CFLAGS</envar> and <envar>CXXFLAGS</envar>,
unset them when building GRUB.</para>

<para>Prepare GRUB for compilation:</para>

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

<para>Compile the package:</para>

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

<para>To test the results, issue:
<userinput>make check</userinput>.</para>

<para>Install the package:</para>

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

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

<para>The <filename class="directory">i386-pc</filename> directory
contains a number of <filename>*stage1_5</filename> files, different
ones for different file systems. Review the files available and copy
the appropriate ones to the <filename
class="directory">/boot/grub</filename> directory. Most users will
copy the <filename>e2fs_stage1_5</filename> and/or
<filename>reiserfs_stage1_5</filename> files.</para>
