Qt in Visual Studio 2012

[daniel347x]

I'd like to suggest that these notes be formalized and displayed prominently in an article linked on the home page. I am a newcomer to Qt, but I am an experienced C++ programmer and I use VS 2012.

It seems to me that integration instructions for Microsoft's current development environment, as of April 2013, might rightfully be considered of paramount importance in terms of a "getting started on Windows" guide.

That way, a user who wishes to integrate Qt with Microsoft's most current IDE will not have to dig through forum postings, as I have had to do.

Thanks,
Dan

Hey guys. I've been working on a community wiki on stackoverflow for this exact problem. It's certainly not perfect and I think needs some work from people who know more than I, but it's a start: http://stackoverflow.com/questions/15826893/getting-qt5-to-install-and-work-with-visual-studio-2012/15893226#15893226

I have carefully followed the steps to build Qt on Windows 7 64-bit (but building Qt in 32-bit mode) in the linked StackOverflow Community Wiki (see previous comment for link), but I cannot overcome the following error while running nmake:

"c1xx : fatal error C1083: Cannot open source file: '.rcc\debug_shared\qrc_mimetypes.cpp': No such file or directory."

(And, indeed, there is no "qrc_mimetypes.cpp" file anywhere in my Qt folder or its subfolders.)

I have posted a new StackOverflow question here: http://stackoverflow.com/questions/15932767/missing-qrc-mimetypes-cpp-while-attempting-to-build-qt-on-windows-7-32-bit-bu

Any help would be appreciated. It seems that building Qt on Windows is not straightforward, even when following all directions with meticulous care. Thanks!

I have resolved the problem to be a catastrophic bug with the Avast! antivirus sandbox. Only a complete uninstallation of Avast! suffices; as long as Avast! remains installed on the system, it is impossible under any circumstances to build Qt.

See http://stackoverflow.com/q/15932767/368896.

If it's a bug with Avast's sandboxing engine, then it needs to be fixed as it will probably frustrate many other users in the meantime. Please notify the Avast developers.

[daniel347x]

I have already alerted Avast. I sent them a detailed email this morning. Frankly, I suspect that their company (with 200,000,000 users) is now too top-heavy to care.

I will report here if and when they respond.

Great, thanks for your efforts :) Fingers crossed that they remember how they grew popular in the first place

Another VS2012 build issue, involving ICU support.

When ICU is enabled ("-icu" on the configure command line, along with a proper build of ICU in VS2012 and proper inclusion of all ICU paths (header, .lib, and .dll)), Line 688 of "qtbase\src\corelib\codecs\qtextcodec.cpp" returns a NULL codec (ICU fails to return a codec) when asked for a codec whose name is "US-ASCII".

Later, this NULL codec variable is dereferenced by the "lrelease.exe" utility when it attempts to perform a translation during the Qt build, which crashes lrelease.exe and causes the Qt build to stop with an error.

It therefore seems to be impossible to include ICU support with a VS2012-compiler 32-bit build of Qt5.

Might someone possibly be able to confirm and/or look into this?

I have posted this question to StackOverflow: http://stackoverflow.com/questions/15975608/icu-support-in-a-32-bit-build-of-qt5-with-the-vs2012-compiler-causes-qt5-build-f

Note the further, related issue that this means that Webkit cannot be built for VS2012, either, since Webkit requires an ICU build of Qt.
