在C ++ / CLR项目中使用C ++ DLL库项目

Question

I'm trying to use a unmanaged C++ DLL library project in a C++ /CLR managed wrapper project, but because the unmanaged project uses <thread> the managed project won't build: error C1189: #error : <thread> is not supported when compiling with /clr or /clr:pure.

to be clear: the managed project itself does NOT use <thread> , only the referenced unmanaged

Is there anyway I can use threads in the unmanaged project and still have it interact properly with the managed wrapper project? (changing the project nature to use managed threads is not an option)

---

Edit: I received -2. I'm not sure why, I couldn't find anything for this specific case and I have no idea what is wrong exactly but it seems like the managed project is also compiling the unmanaged project?

Answer 1

Does the include file for the unmanaged project include <thread> , directly or indirectly? That's probably the cause of the error.

Try to make the interface header of the unmanaged project just define the interface, and not include any implementation-dependent include files.
