I don't know how to check this.

Right. I didn't know that.

That's true. It breaks this function badly, but I don't know if it wasn't broken before. Someone with knowledge should revise that and prove that this plugin works at all.

Then just add a comment, that this is a work around and has to be fixed later.

Oh, this is more complicated than I thought. What about using:

set(CMAKE_REQUIRED_INCLUDES "${LIBOFX_INCLUDE_DIR}")
check_struct_has_member("struct OfxFiLogin" "clientuid" "libofx/libofx.h" LIBOFX_HAVE_CLIENTUID)
unset(CMAKE_REQUIRED_INCLUDES)

This does not require compiler distinctions and is shorter. Since we have FindLibOfx.cmake under our control this code can go there (then we do not worry about setting and unsetting CMAKE_REQUIRED_INCLUDES). However, this is not required (and the lientuid var has to be marked as cached).

Btw: CMake docu for CMAKE_REQUIRED_INCLUDES in this context is here: https://cmake.org/cmake/help/latest/module/CheckStructHasMember.html

Can you send me the MSVC error this line causes? Then I can try to handle that.

As I remember correctly, I tried with CMAKE_REQUIRED_INCLUDES and failed. If it works for you on MS Windows, then go for it.
If you checked it only on Linux then please don't touch it.

Hey Łukasz and Christian,

it's been a while, but I think I ran into that issue before. It is somehow related to which methods MSVC exports into a dll. I somewhere found the info this might be related to the order libraries are linked, but couldn't really get it to work. I didn't bother figuring out the details back then because I wasn't patient enough, but "fixed" it rather brutally by patching mymoneyaccount.h in craft as follows. That way I was able to successfully compile (although, if I remember correctly, the result looked terrible because all icons were missing).

This is certainly not elegant, but maybe it's a good starting point for either of you to dig deeper into it ?

Kind Regards,
Marc

Don't define EXPORT yourself. Use KMM_MYMONEY_EXPORT which is declared by cmake in kmm_mymoney_export.h and should have the necessary definitions for your build environment.
