Jason,
When you compile and link, make sure you have your "Build", "Set active
configuration" settings for "Debug.
The mak files contain both "Debug" and "Release" settings but one or the
other is actually chosen in the "Build" environment.
It is possible that somehow or other, the *.def file is missing from
your project. This very short text file is required so that during the
linking of the compiled objects, the proper functions are exported so that
the rest of the world can get access to them. An example of what the *.def
file should look like is as follows:
___________________________________________
LIBRARY FX_ATS_ff.dll
;EXETYPE WINDOWS
HEAPSIZE 1024
EXPORTS
RMACreateInstance
---------------------------
The only required parameter is the "Exports" statement. The "library"
statement just needs to agree with the name of the dll as it is created
during linking and isn't even needed, the "Exetype" isn't used and in this
case is commented out by the ";" and the "heapsize" which in this casse is
the default size anyway just tells the system how much memeory to allocate
for the dll when it is loaded.
I see by your last paragraph, if it is exactly correct, that you are not
including the *.def file, something that has tripped me up too many times
for me to still laugh at! ;-)
I would be willing to bet that if you include that file that everything
will start working again. BTW, it is an excellent test to view the
RealPlayer copyright information to see if the plug-ins got loaded or not.
It is a simple test that many people forget about.
Good luck and if you have anymore questions, please repost.
