Is MFC not supported?

[tjdskaqks]

It was built in a Windows environment.
However, the project I want to add is currently being built with MFC, vs 2010 x86.
I also set the header file and link path.
However, an error occurs as follows.

error LNK2001 unresolved external symbol "extern "C" int __cdecl sentry_close(void)" (?sentry_close@@$$J0YAHXZ) test D:\test.obj 1

I don't think this has anything to do with using MFC. Can you please provide more details on how you are building the library, including:

• the CMake invocation on the command line
• the CMake configuration output
• a short description of how you link the library to your program (is it possible that you didn't add the library under Project Properties -> Linker -> Input -> Additional Dependencies)
  Thanks!

check whether sentry_close is in that list (is this the only function the linker is complaining about?
--> No, This applies to all functions used.

It looks like the library build exports the functions correctly. You said, that you use VS 2010 x86 in the application, but you seem to build with mingw w64. Is it possible that you build an x64 library that you link to x86 application?

Was this the issue @tjdskaqks?

[tjdskaqks]

@supervacuus
sorry. I just gave up. 😥

[supervacuus]

Okay, I'm so sorry to hear. Let me know if you ever want to tackle this again.
