I'm absolutely new to Qt. I've made a program using C++ in Visual Studio 2010 in which I use the external library from Dcmtk. I now want to add a user interface to that program. In my original program I had to change the C++ <code>Runtime Library</code> in Code Generation setting in Visual Studio to <code>Multi-Threaded(/MT)</code> from <code>Multi-Threaded Debug DLL</code> otherwise the program would not work. I have to do the same in QtCreator, but I don't know how to change that setting in Qt. Could you please suggest how I should approach that? Thanks.

<code>/MT</code> is a compiler flag. You can specify flags in your .pro file like this: <code>QMAKE_CXXFLAGS += /MT</code> Moreover, you probably want to specify <code>/MTd</code> for debug build: <pre class="prettyprint"><code>Release:QMAKE_CXXFLAGS += /MT Debug:QMAKE_CXXFLAGS += /MTd </code></pre>

In the version of QT 5.5 the variable is QMAKE_CXXFLAGS_DEBUG and QMAKE_CXXFLAGS_RELEASE so the new working solution for QT 5.5 is: <pre class="prettyprint"><code>QMAKE_CXXFLAGS_DEBUG += /MTd QMAKE_CXXFLAGS_RELEASE += /MT </code></pre>

Moreover, you probably want to specify /MTd for debug build:

Release:QMAKE_CXXFLAGS += /MT
Debug:QMAKE_CXXFLAGS += /MTd

In the version of QT 5.5 the variable is QMAKE_CXXFLAGS_DEBUG and QMAKE_CXXFLAGS_RELEASE so the new working solution for QT 5.5 is:

QMAKE_CXXFLAGS_DEBUG += /MTd
QMAKE_CXXFLAGS_RELEASE += /MT
