I am trying to compile protobuf-2.3.0.tar.gz & protobuf-c-0.13.tar.gz on the latest CYGWIN platform in windows.
While compiling protobuf-c-0.13.tar.gz i am ending up with the following error: Is there any flag to update LD_FLAGS?? (even though i am able to compile 2.3.0 without setting any flags and my understanding was there is no need to set any flags and i am through with this apporach in linux with out any problems).
Any help is really appreciated..

perhaps you need to add -Llibdir to your LDFLAGS.
