Getting Qt Creator setup properly

hdevine

The QT version says "Qt in PATH". When I check Tools->Options->Qt4, I get the following:

Auto-detected
Qt in Path /usr/bin/qmake-qt4
Manual
Qt 4.6.3 OpenSource /opt/qtsdk-2010.04/qt/bin/qmake

Sorry if these seem like dumb questions. I'm feeling my away around Qt after being a Windows/MFC/Developer Studio programmer for over 10 years.

I bet your Qt in Path has version < 4.6. The item QKeySequence::Quit appeared in QKeySequence::StandardKey enum only in Qt 4.6 (according to documentation). Modify the build settings for your project in Qt Creator and explicitly tell it to use Qt 4.6.3.

hdevine

When I do that, it says "This Qt version is invalid" next to the Qt version drop down box (which says Qt 4.6.3 OpenSource at the moment). So, how do I get the Creator to see a valid Qt version?

Harry

This is means that Qt 4.6.3 has not been registered correctly.
Please show the output of the following cmd

$ ls -l/opt/qtsdk-2010.04/qt/bin

I started looking back at this again today, and I see that the Qt4 section in Qt Creator says "Qt version is not properly installed, please run make install". So, when I do that in the area where I have the 4.6.3 source, I get the following compile error:

I did some Googling and saw a suggestion to make sure that the gstreamer headers are installed. I'm running 32 bit Fedora 11 and I have the gstreamer stuff installed already from what I can tell. Any ideas?

Harry

lyuts

The directory with gstreamer headers should be passed via -I flag during compilation. Something like

-I/usr/include/gstreamer-0.10

This can be done in .pro file by adding this path to INCLUDEPATH.

hdevine

It appears like I don't have the gstreamer headers. I don't see anything like that under /usr/include on my system. I also tried to look for gst.h (which was mentioned in the output above) and I don't have that either. Do you know what package I need to install to get those headers?

Thanks,
Harry

lyuts

The name can vary a little bit depending on your distro. But i think it should be easy for you to figure out the correct name since the package name should have a suffix 'dev' or 'devel'. For openSUSE it is gstreamer-0_10-devel.

hdevine

OK, I got it working finally. I installed the gstreamer-devel package for Fedora 11, redownloaded the SDK, and rebuilt the source. Then I told QT Creator to use the newly build source and the demos build. Now its time to start learning Qt!

Thanks,
Harry

Great, have fun!

i had same problem but now i think i can fix it
