Re: [certi-dev] Problem building CERTI on Mac OS X

[Mark Brown]

It still doesn't quite work - I commented out the lines

IF (NOT WIN32)
...
#FIND_LIBRARY(RT_LIBRARY rt)
#SET(CMAKE_REQUIRES_LIBRARIES ${CMAKE_REQUIRED_LIBRARIES} ${RT_LIBRARY})

and tried again but it still fails to link (library not found for -lrt) 
so I'm not sure where it's trying to pick that up from. However, I don't 
think I need the test program.

Cheers,
Mark.
