When I build my project using the darwin toolset I get the following
warning:
g++: unrecognized option `-pthread'
when building, and the following error when linking:
ld: can't locate file for: -lrt
I traced the -lrt back to the bottom of the gcc toolset. In the default
case of that switch statement, it says:
flags gcc OPTIONS <threading>multi : -pthread ;
flags gcc FINDLIBS-SA <threading>multi : rt ;
If I remove those lines, both the warning and the error goes away.
I'm using the latest released version from source forge.
