Cross-Compiled Linux From Scratch - Version 1.0.0rc6-PowerPC

Chapter 10. Installing Basic System Software

10.57. Yaboot-1.3.13

The Yaboot package contains a PowerPC Boot Loader for machines using Open Firmware such as NewWorld Macintoshes.

10.57.1. Installation of Yaboot

Yaboot has a compilation error. The following patch properly fixes the issue: 

patch -Np1 -i ../yaboot-1.3.13-fix-1.patch

The following patch removes a redundant test which prevents ofpath from executing against SATA disks: 

patch -Np1 -i ../yaboot-1.3.13-ofpath_sata-1.patch

The supplied man pages have /usr/local in the text. This sed will correct that: 

sed -i 's%/usr/local%/usr%' man/*

Compile the package: 

make PREFIX=/usr

Install the package: 

make PREFIX=/usr install
