Hello Pavel,

I had the same problems on Fedora15. I used these two patches to fix the problems.

Best regards,
Florian

Hello Miroslav!

I have experienced the same problem you had - http://www.aps.anl.gov/epics/tech-talk/2011/msg00964.php
How did you resolve it? I have changed "size_t _refCount;" to "std :: size_t _refCount;" in epicsSingleton.h as was proposed. But still I get this:

In file included from ../cac.cpp:39:0:
