rttlua: LD_LIBRARY_PATH cleared

Submitted by ereekmans on Wed, 2012-07-11 13:47

Hello,

The LD_LIBRARY_PATH variable seems to be cleared in rttlua-gnulinux:

$ rosrun ocl rttlua-gnulinux -i
> ld = os.getenv("LD_LIBRARY_PATH")
> print(ld)
nil

I am using ROS Fuerte and the ocl toolchain-2.5 branch on an Ubuntu 12.04
kernel.

Any ideas?

Regards,
Eli Reekmans

My guess is that either your rttlua binary has set setuid/setgid or
you have configured capabilities(7), IIRC in both cases
LD_LIBRARY_PATH is cleared for security reasons.

What are you trying to do?
