Re: LD_RUN_PATH required? SUNWspro/GCC ld differences?

Here are some comments from a Solaris guru (not me...):

> LD_LIBRARY_PATH does NOT contain the libaceclnt.so (third party .so lib).
> LD_RUN_PATH is empty.

Where exactly is libaceclnt.so on the two machines?  I'd guess
/usr/local/lib...

There are *significant* differences between the two versions - one is built 
with shrplib, one without, and the libpths are different - specifically the 
working one includes /usr/local/lib, and the broken one doesn't.

He can verify this by using 'ldd' and 'dump -Lv' on the various perl, 
libperl.so and module .so files and looking at the dependencies.  Another 
trick is to do 'LD_DEBUG=libs perl sometestscript' which will display the 
library search processing.

As for a fix, he can hack the module Makefile.PL - I'm not sure which would 
work best, adding -R<library path> to LIBS, or using
     dynamic_lib  => { OTHERLDFLAGS => '-R<library path>' }
Whatever, he should use 'dump -Lv' on the resulting .so and check that 
libaceclnt.so appears in the NEEDED section, and the directory it is in 
appears in RUNPATH/RPATH.
