To conclude the topic of using crle(1) and the observed error message:
> ld.so.1: ps: fatal: /usr/lib/libc.so.1: wrong ELF class: ELFCLASS32
> Killed
I had asked (in a private email):
> If you run "truss -fe" you'll see the environment passed to each process.
> Is LD_CONFIG shown to exist?
And the answer was that LD_CONFIG was set. So, through a series of historic
events it seemed that a default configuration file was being created in
/var/ld/ld.config, but that an LD_CONFIG setting in /etc/profile was causing
all applications (32-bit and 64-bit) to see this one file.
Here's a wrap up of some of my clarifications and recommendations:
The 32-bit ld.so.1 looks for /var/ld/ld.config by default,
you do not have to set LD_CONFIG.
The 64-bit ld.so.1 looks for /var/ld/64/ld.config by default,
you do not have to set LD_CONFIG.
By setting LD_CONFIG, *all* processes that see this environment
variable are reading the associated configuration file. So,
if this configuration file uses 32-bit paths, any 64-bit process
that sees the environment variable is being given bad information.
And similarly, if this configuration file uses 64-bit paths, any
32-bit process that sees the environment variable is being given
bad information.
Use LD_CONFIG to point to a "temporary" configuration file as you
experiment. Better yet, use LD_CONFIG_32 and LD_CONFIG_64 to
be precise in regards the configuration files use.
Once happy with the configuration file, populate it in the
default location (/var/ld/ld.config or /var/ld/64/ld.config)
and remove any LD_CONFIG settings.
It would be more optimal, and perhaps less confusing to use:
% crle -u -l /your/32-bit/libs:/3rd-party/32-bit/libs
This will create /var/ld/ld.config, and append your search paths
to the 32-bit system defaults. This configuration file will be used by
default by all 32-bit processes.
% crle -64 -u -l /your/64-bit/libs:/3rd-party/64-bit/libs
This will create /var/ld/64/ld.config, and append your search paths
to the 64-bit system defaults. This configuration file will be used by
default by all 64-bit processes.
Unset LD_CONFIG.
It's obvious from these discussions that the crle(1) man page could do
with some improvement, so I'll work to populate the information above
into the man page over the coming months.
