Qmake: Error compiling qtforms from the Maya devkit [C++]

[Settoken]

I'm trying to compile qtforms which is one of the Qt example plugins provided by Autodesk with the Maya Devkit. It demonstrates 3 different ways to integrate Qt in a maya plugin. 

You can find it here: devkit plug-ins 

I've been through several issues already but I am now stuck with errors while compiling.Here is the output:

I've found this thread which seems pretty similar to what I'm experiencing right now. 

Any idea how I can fix this ?

Are you using a compiler and Qt version that is compatible with Maya 2016?

Well I'm not sure about the compiler. I'm using the visual studio 2013 command prompt, QMAKESPEC is set on win32-msvc2010, and the Qt version is the 4.8.6 shipping with Maya2016 and the devkit.

I've found this, but I don't really know what I'm supposed to do with that information.

[Justin Israel]

I don't know much about compiling on Windows, but that is telling you the required version of Visual Studio, for compatibility with Maya 2016. I know that when compiling Maya plugins, on Windows, you have to use the right msvc version to match the particular Maya. 

Aside from that, your error suggests missing includes. Have you tried adding:   #include <windows.h> 

to your plugin?

Yes but no result.

Maya 2016 on windows uses VS2012 not 2013. So you'll need to install the other compiler. I believe there is a way to tell VS2013 to use older compilers, but I'm not sure how on earth to go about doing that.
Also if you don't want the entire VS2012 installation you should be able to use the Windows8 SDK instead, it contains the compilers and a command line shortcut to run everything in.

Unfortunately I've already tried to compile with VS2012. I just installed the update 4 to see if it helps but it doesn't.

According to this: http://stackoverflow.com/questions/6943865/visual-c-cant-find-windows-types-like-pvoid-dword-ulong-etc, I've given #include<windows.h> another try, this time including it before anything else in qtForms.h and it worked.

Thank you for your help.

Ah cool. Glad that ended up sorting it out. Because I was out of suggestions :-)
