I have a piece of code that can be compiled using the /MD keyword and another one that can be compiled only using the /MT keyword. Is there a way I could combine these two into one project, so that I can call the functions in both from each code?
Thanks.
probably not. you'll almost certainly end up with multiply defined symbols in the link table.
why can't you re-compile one or the other?
That's bad news then... One is written using the .NET library (but in C++) and needs to be compiled using /clr (no support for /MT). The other one relies on a 3rd party API (Perforce -p4api) that must be compiled using /MT. I need to use the functions of the API in my .NET code, else a nearly 3-day effort is going into the trash can.
if the code compiled with Multithreaded DLL is dll itself - should not be a problem...
Warnings about multiple definitions can be ignored in this case (i suppose) because both versions are release and multithreaded...
I'm not sure that versions of the CRT used by the NET code and by the standard C++ are the same... So the conflicts there could make a problem...
Have you tried to link these parts of the code?
Your third party API is compiled into a DLL?
You may be able to just scrap the import library and explicitly load the library (LoadLibrary(), FreeLibrary(), GetProcAddress()) as it really shouldn't matter how the DLL is implemented if you're not using an import library.
