I need to use Papi on a ARMv7l architecture, the OS is "Linux 3.2.0-1000-highbank #142-Ubuntu".
I downloaded the last version ans compiled it without any errors.
However the 'make test' return me
ctests/zero
test_utils.c FAILED
Line # 697
Error: Zero Counters Available! PAPI Won't like this!
I read that ubuntu may prevent access to those counters for non-root user, but being root does not change a thing.

Is there really a platform problem ? Or did I miss a step somewhere (which is likely^^)
Thank you for your help.
Marc.
EDIT:
The problem have been solved by upgrading to Papi 5.2.0
