Undeclared identifier 'o2'

Dear all,

I’m running the simulation challenge script O2/prodtests/sim_challenge.sh -n 10 -s pp and I’m getting these errors in the execution of the macros:

Processing /Users/auras/alisoft/sw/osx_x86-64/O2/dev-local2/share/macro/analyzeHits.C…
In file included from input_line_9:1:
/Users/auras/alisoft/sw/osx_x86-64/O2/dev-local2/share/macro/analyzeHits.C:116:15: error: use of undeclared identifier ‘o2’
void addHit(o2::trd::Hit const& hit)
^

Any hint?

Thanks, cheers
Antonio
