Had this already yesterday with two questions which were "pulled". For one I could even understand it.
Today (just now) the question here
https://superuser.com/questions/252728/library-loading-order
... disappeared while I was typing my answer.
What exactly was wrong with the question? Even though it was about a particular program which exhibited the behavior thanks to loader configuration, the use of environment variables to control the loader and figuring out loader issues is of value to more than the poster of the question. Is it not?
Here's the answer I was preparing so far:
See: http://linux.die.net/man/8/ld-linux (or man ld.so
)
Use the environment variables LD_DEBUG
and LD_DEBUG_OUTPUT
to write a log file with the details of which lib was picked for which symbols.
