load a shared lib created using gcc/Cygwin
Thu Jun 30 23:51:00 GMT 2005
I made a mistake in the previous reply.
Here I state my question again.
mylib.dll was built using gcc/cygwin based on some library that
might depends on cygwin1.dll.
I don't want to load cygwin1.dll explicitly, but I do need to load
mylib.dll dynamically at run-time in an application which was built by
Visual C++ or .NET.
How should I do?
