Re: How to make an application look somewhere other than /lib for ld-linux.so.2

Ok - thanks.

For #1, if I build with --static, then no libraries can be linked in 
dynamically at runtime...  I need to do this for some custom Qt libraries 
and plugins, so I can't just make a completely static executable.  This is 
unfortunate - the resulting binaries would be big, but they'd work on any 
distro.

#2 - I'd never heard of LSB or lsbcc...  I've just done a google and turned 
up an article on an IBM website on building binary-compatible Linux 
applications...  Thanks for the pointer on this one - it looks like this may 
be the way to go.
