10.72.1. Installation of Yaboot
Yaboot defaults to build as 32bit, so we need to pass appropriate
options to both the compiler and the linker. To prevent the build
from failing due to compiler warnings, the -Werror flag is removed.
The Makefile already overrides any CC and ignores LDFLAGS in favour
of its own variables, so we need to use the following seds for a
successful compile and install.
sed -i -e "s/m32/m64/g" \
-e "s/-Werror//" \
-e "s/elf32ppclinux/elf64ppc/" Makefile
The meaning of the sed parameters:
-
"s/m32/m64/g"
-
Replaces -m32 with -m64 to force gcc to create 64-bit code
when compiling yaboot.
-
"s/-Werror//"
-
This deletes the -Werror flag from the Makefile.
-
"s/elf32ppclinux/elf64ppc/"
-
This replaces the 32 bit emulation with a 64 bit emulation
flag to force ld to use a suitable 64-bit
emulation picked from the output of 'ld -V'.
The following patch adds stub functions for newer e2fsprogs
releases:
patch -Np1 -i ../yaboot-1.3.17-stubfuncs-1.patch
The following patch adds Parted support to yabootconfig:
patch -Np1 -i ../yaboot-1.3.17-parted-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:
![[Important]](../images/important.png)
Important
The install of yaboot can fail if you miss any of the patches or
seds. ld will issue
warnings, but the install will appear to complete successfully.
That would result in an unbootable system, so you need to log the
output to check it.
make PREFIX=/usr install 2>&1 | tee instlog
To ensure that the install was successful, run the following
command:
grep 'powerpc:common64' instlog
If the command gave you any
output (... is incompatible with powerpc:common output) the build
of yaboot is broken and you will have to correct your error(s) and
repeat it.
