[Scons-users] scons and openmp problem

[Bill Deegan]

Do you have multitple versions of gcc installed?
What's the path to the one you want to use?

My first guess is you're picking up and older version of g++ from /usr/bin
and your gcc 5.3.0 is installed elsewhere so you'll have to be explicit
about it's location.
