How to check the installed Qt version on Mac OS X

Is there a command to check the version of the installed Qt on Mac OS X. My Mac OS X version is 10.6.7.

Eidt: Update the status 10/28/2011

When running /usr/sbin/system_profiler SPFrameworksDataType, the version of the QTkit is 7.6.6.

The value of the macro QT_VERSION_STR in qglobal.h is "4.7.2".

I'm confused why the two version strings are different? Obviously, the version string "4.7.2" is what I want.

Thanks, Jeffrey

If installed via brew, this will get the version into the variable QT_VERSION

QT_VERSION=`brew list --versions qt5 | sed -En -e 's/qt ([0-9._]+).*/\1/p'`

You can then invoke it thusly:

/usr/local/Cellar/qt/${QT_VERSION}/bin/qmake

On terminal:

qmake -v

It should return versions of QMake and Qt.

Something like:

QMake version 3.0

Using Qt version 5.6.2 in /Users/thiago/anaconda/lib

If you installed with brew, just do...

brew info qt or brew info qt5

Update:

Doing it this way will cut out all the extra stuff and only show versions.

brew list --versions qt or brew list --versions qt5

Here's a nice cheatsheet for brew, btw: http://ricostacruz.com/cheatsheets/homebrew.html

cd to the include directory where your qt headers are located and then...

grep --include=\*.h -rnw ./ -e "QT_VERSION_STR"

which should output something like...

./QtCore/qglobal.h:40:#define QT_VERSION_STR "5.4.2"

Go to your "Applications>>Tools" folder and launch the System-Profiler. Look at "Software>>Frameworks>>QTKit". There you will find the version.

To get in in a terminal (to use it from Java for example) execute the following command:

  /usr/sbin/system_profiler SPFrameworksDataType

There you will find something like this:

  QTKit:

    Version: 7.7
    Last Modified: 13.04.11 16:02
    Kind: Universal
    64-Bit (Intel): Yes
    Get Info String: QTKit 7.7, Copyright 2003-2011, Apple Inc.
    Location: /System/Library/Frameworks/QTKit.framework
    Private: No

In XCode there should be an environment-variable available.

IF you speak about programming here...: At compile time you can check Qt's version with QT_VERSION_STR. During runtime you can use qVersion(). Obviously, the version you build you application with does not always match the version you run it with.

If you can find where Qt's headers are installed, qglobal.h contains a define for QT_VERSION_STR. You can simply grep for that.
