when I start ROOT5.34/30 the following error appear:

Error in <TSystem::ExpandFileName>: input: $/bin/g++, output: $/bin/g++

add info:

Chassis: laptop
Operating System: Debian GNU/Linux 8.1 (jessie)
Kernel: Linux 3.16.0-4-amd64
Architecture: x86-64


Please, could anyone help me to correct it?

I’m sorry if my problem has already been solved and, in such a case, I kindly ask to send me the link to the right post.

thank you in advance
