Re: symbol lookup error: /usr/lib/libPhysics.so: undefined symbol: gRandom

Hi,

You can preload all the libraries we "usually" recommend by running root-config --libs. You could to take those (the ones starting with -l...) and LD_PRELOAD them all:

LD_PRELOAD="/usr/lib/libRIO.so /usr/lib/libTree.so /usr/lib/libCore.so ..." ./binary

Cheers, Axel.
