<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 un-setting them when building
|
|
Grub.</para>
|
|
|
|
<para>First prepare Grub for compilation:</para>
|
|
|
|
<screen><userinput>./configure --prefix=/usr</userinput></screen>
|
|
|
|
<para>A few of the files comprising Grub have issues with optimizations done
|
|
by GCC 3.4. Compile these few files with known-good optimizations:</para>
|
|
|
|
<screen><userinput>make -C stage2 STAGE2_CFLAGS=-O2 \
|
|
pre_stage2_exec-builtins.o pre_stage2_exec-serial.o</userinput></screen>
|
|
|
|
<para>Now compile the rest of the package:</para>
|
|
|
|
<screen><userinput>make</userinput></screen>
|
|
|
|
<para>To test the results, issue:
|
|
<userinput>make check</userinput>.</para>
|
|
|
|
<para>Now 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 file systems. 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>
