Cross-Compiled Linux From Scratch - Version 3.0.0-SYSTEMD-MIPS64-Multilib

Chapter 10. Installing Basic System Software

10.130. Colo-1.22

The Colo package contains the Cobalt Boot Loader.

10.130.1. Installation of Colo

[Note]

Note

This bootloader is for the MIPS based cobalt servers RaQ, RaQ2, Qube, or the Qube2.

This patch updates the Colo bootloader to build under 64 bit: 

patch -Np1 -i ../colo-1.22-make_fix-1.patch

This patch fixes a relocation error when linking with Binutils: 

patch -Np1 -i ../colo-1.22-relocation_fix-1.patch

Disable -Werror in one of the Makefiles to prevent a compile failure: 

sed -i '/^CFLAGS/s/-Werror //' stage2/Makefile

Compile the Colo package: 

make binary
make CC="gcc ${BUILD64}" tooldirs

Install the package: 

install -dv  /usr/lib/colo/examples
install -v chain/colo-chain.elf /usr/lib/colo
install -v tools/lcdtools/e2fsck-lcd/e2fsck-lcd /sbin
