10.88.1. Installation of GRUB
![[Note]](../images/note.png)
Note
This package is known to have issues when its default optimization
flags (including the -march
and -mcpu
options) are changed. If any environment variables that override default
optimizations have been defined, such as CFLAGS
and
CXXFLAGS
, unset them when building GRUB.
Prepare GRUB for compilation:
./configure --prefix=/usr \
--sysconfdir=/etc --disable-werror
Compile the package:
make
To test GRUB you must have QEMU installed and then, issue:
make check
.
Install the package:
make install
10.88.2. Configuring GRUB
Now that grub is installed, we need to configure the defaults that
will be used to generate the configuration after we install the kernel.
Create this file with the following:
install -m755 -dv /etc/default
cat > /etc/default/grub << "EOF"
# Begin /etc/default/grub
GRUB_DEFAULT=0
#GRUB_SAVEDEFAULT=true
GRUB_HIDDEN_TIMEOUT=
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=Cross-LFS
GRUB_CMDLINE_LINUX=""
GRUB_CMDLINE_LINUX_DEFAULT=""
#GRUB_TERMINAL=console
#GRUB_GFXMODE=640x480
#GRUB_GFXPAYLOAD_LINUX=keep
#GRUB_DISABLE_LINUX_UUID=true
#GRUB_DISABLE_LINUX_RECOVERY=true
#GRUB_INIT_TUNE="480 440 1"
#GRUB_DISABLE_OS_PROBER=true
# End /etc/default/grub
