crle

[Igaduma]

Hi All,

Slow crle death here.
Got a binary that is called by a script.

Script:
# Script to control the operation of the Sun loader when loading eProcess executables
LD_CONFIG=/fnsw/bin/vw_virtual_table.conf
export LD_CONFIG
exec VWJs.X $*

The binary lacks some libs.
When setting LD_LIBRARY_PATH to where the libs are, no luck.
When linking them into /usr/lib ,it finds them.

crle -c vw_virtual_table.conf contains this:
Configuration file [version 4]: vw_virtual_table.conf [ RTLD_REL_RELATIVE ]
Default Library Path (ELF): /usr/lib (system default)
Trusted Directories (ELF): /usr/lib/secure (system default)

when executing the crle -u -c vw_virtual_table.conf and trying to add a different location, crle seems to loose all the directory & alternate pointers.

How are the directories & alternate pointers then created when the command in crle -c <conf_file> doesn't retain them ?

can I see the output of with a set LD_LIBRARY_PATH and without
# ldd ./crle

Hi DaFranze

What you want is a ldd of the called binary, once without LD path & once with LD path ?

ldd /usr/bin/crle gives this:

bash-2.05$ ldd /usr/bin/crle
libelf.so.1 => /usr/bin/../lib/libelf.so.1
libdl.so.1 => /usr/bin/../lib/libdl.so.1
libc.so.1 => /usr/bin/../lib/libc.so.1
/usr/platform/FJSV,GPUSK/lib/libc_psr.so.1

strange path string /usr/bin/../lib/ - I mean this is ok, but I have never seen this. There are no unresolved paths to libs, that was my major goal.
I suggest to add a
ldd /usr/bin/crle >> /tmp/lddcrle
to your script and check if the libs are resolved by the script, too.

Best Regards, Franz
