PPC: Textual blur in 10.7.4 (32bit) and 10.8.4 (Multilib) (Cfg dynlinker)

[Thomas]

In chapter 10.7.4 of 32 bit powerpc book and chapter 10.8.4 of ppc64 multilib book (Configuring the dynamic linker) there is /lib/ld-linux.so.2 named as default linker, mostly true but not on PPC systems. There it should read as /lib/ld.so.1 and/or /lib64/ld64.so.

This sounds as if it might affect other arches too. I'll take a look.

Sparc64 and Sparcv9 use ld-linux.so.2. Alpha uses ld-linux.so.2 x86 uses ld-linux.so.2 x86_64 uses ld-linux-x86-64.so.2

This has gone a while without any changes, what's the status of it?

Replying to Moody:

In chapter 10.7.4 (Configuring the dynamic linker) there is /lib/ld-linux.so.2 named as default linker, mostly true but not on PPC systems. There it should read as /lib/ld.so.1, isn't it?

This section no longer exists and I don't see anywhere in the book where it talks about default linker. It is now in section 10.8.4. I confirm ld.so.1 for this ppc and ppc64, and no other architecture. If anyone else has no objections, the book text should read:

By default, the 32bit dynamic loader (/lib/ld.so.1) searches through /lib, /usr/lib, and the 64bit dynamic loader (/lib64/ld64.so.1) searches through /lib64, /usr/lib64 for dynamic libraries that are needed by programs as they are run. However, if there are libraries in directories other than these, they need to be added to the /etc/ld.so.conf file in order for the dynamic loader to find them. Some directories that are commonly known to contain additional libraries are /usr/local/lib, /usr/local/lib64, /opt/lib, and /opt/lib64, so add those directories to the dynamic loader's search path.

Someone else may suggest a better structure for the entry in the book, but that is the proper way it should read for ppc64 multilib. As it is now seems pretty correct for ppc except ld-linux.so.2 should read ld.so.1 for the default linker.

The ldso names on the following archs are:

x86	ld-linux.so.2
x86_64	ld-linux-x86-64.so.2
x86_64-64	ld-linux-x86-64.so.2
ppc	ld.so.1
ppc64	ld64.so
sparc	ld-linux.so.2
sparc64	ld-linux.so.2
sparc64-64	ld-linux.so.2
alpha	ld-linux.so.2
mips	ld.so.1
mips64	ld.so.1
mips64-64	ld.so.1

Reassigning this to myself to update right now
