Building ActiveQt Applications (COM) with MinGW

Question

I am using Qt 4.6.3 with MinGW on Windows to create Qt applications and now you need to add a COM interface to my application. I enabled ActiveQt, but was getting post-link errors because I was missing a copy of the MIDL compiler. I downloaded a copy of the latest MS Windows SDK, which includes MIDL, but now MIDL complains that it cannot find cl.exe. The only conclusion I can make is that you can only create ActiveQt applications using the MS compiler, which I would prefer to avoid. Is there a way to get this to work with MinGW or am I out of luck?

Answer 1

Using the MS compiler and tools seems to be the only reliable way to make this work.

Answer 2

Well, you can create ActiveQt with MinGW, but using a bunch of COM files on top of this may not be possible because it may or may not be present in MinGW. Some thoughts:

• Using any MS SDK tools with MinGW will not work (the exception is mingw.org + DXSDK, which should work most of the time).

• Are you sure that when compiling you link all the necessary libraries? I can no longer help if you are not showing the exact error messages.

• mingw-w32/w64 "Windows SDK GCC"; /, . x64 x86 DX. COM-, , , mingw.org. , .
