Say I have a static C++ lib, static.lib and I want to call some functions from a C++ shared lib, say shared.lib. Is it possible? Now assume that I have another shared lib, say shared2.lib which links to static.lib but does not link to shared.lib. Does the linker automatically link shared2.lib to shared.lib in this case? I am using Micr...

When I reversed the arguments the program stopped aborting. This is an example of the syntax I'm using. The thing is, a_ needs to be init...
