Re: [CMake] QTCreator project to VS2008 problems
Thanks for all the help, I got it working. I was not including the automoc generated headers or wrapped ui in the executables, I was adding the original files instead. - Original Message - From: "John Drescher" To: "Michael Jackson" Cc: Sent: Friday, March 19, 2010 1:40 PM Subject: Re: [CMake] QTCreator project to VS2008 problems I may have worded that badly, so just to clarify - the QT I am using to create the VS2008 project (the one used with cmake) was compiled with VS2008, it's just the original code that was created in a mingw compiled QTCreator.

Re: [CMake] QTCreator project to VS2008 problems
You may want to take a look at the following sample project:
http://www.cmake.org/Wiki/images/2/25/QtTest-Package-Example.zip
While the project was geared towards OS X specific topics the project
will compile and run on any platform that Qt is supported on,
Including MinGW and Visual Studio.

To me this is a problem with what gets run with moc.I am using Qt and
vs2008 every day so I can assure you that it works. Try adding the
header file to the auto moc. You should have the header files in the
source anyways.

Hi John,
Thanks for the reply - I added mainwindow.h to the automoc but I get
the same thing - I thought it might be the QMetaobject header or
library it was looking for, looking at the the error messages, but I
checked and the header is there, and the search paths are correct. I
built the QTProject with a mingw compiled version of QTCreator -
this wouldn't matter would it?
