I have installed Qt 5.1 VS2012 , but I do not have VS2012 installed. when I want to compile a project, I get an error saying that no compiler configuration is present. Is there a way not to install VS2012 completely ? forexample just installing its compiler alone ?

I downloaded the QT 5.2 build for MingW/OpenGL build and installed it. When I run QTCreator and try to create a project, I can't set it up because there is no kit available to choose from. I have MingW installed, so I tried to point QT to this installation, but there is qmake as well missing. I'm not sure if the manual configuration of the compiler would suffice to have a kit to choose from, but that would be my expectation.
So the question is, how do I setup QT properly that it recognizes my MingW installation and how do I get qmake to continue with QT? After downloading a 600MB package I would have expected that it works out of the box.
OS is Windows 7 and my MingW uses gcc 4.8 so it should be the same version that QT brings in it's package as well.
I just installed Qt 5.2 package on ubuntu. I simply created a Qt widget application, and when I tried to build it, I got the following message:
Qt Creator needs a compiler set up to build. Configure a compiler in
kit options
I have tried several things, all of which were unsuccessful. I tried setting the compiler kit to
Desktop Qt 5.2.0 GCC 32bit (default)
However it didn't work
After that I set the compiler to
GCC (x86 32bit in use/bin)
However that didn't work either.
I also tried adding gcc manually and gave it the path
/usr/bin/g++-4.6
but it still didn't work.
This is what appears in there Qt Version tab
This is what I get when I remove the .pro.user file and restart the IDE, Whats the difference between configuring a project as Desktop and Desktop Qt 5.2.0 GCC 32bit?
Qt Creator needs a version of tools that are able to link against the Qt binaries that the downloaded package contains. In your case, the local toolchain and the binaries don't match. That means that you would actually have to build the Qt with your toolkit and make sure that QtCreator can find the built binaries.
The simpler way for Ubuntu is to use the packaged version of the tools; they play well with the already delivered binaries. Use sudo apt-get install qtcreator to install it with all the dependencies.
I've recently came to linux from a 1 year Windows run in Qt so I don't know how this works exactly and couldn't find any thing decent. So here it is :
As is obvious from the title I'm trying to install Qt 5.1.1 and Qwt 6.1.0 in Ubuntu 12.04. I have written a project with the same versions in Windows and now I want to run the project in Linux. The problem is I don't know If I'm doing the installing process right!
I installed Qt 5.1.1 in /opt/qt5.1.1 and compiled Qwt 6.1.0 to /usr/local. I copied the files in include, lib, plugin/designer to the related folders in qt 5.1.1. After this the plugin is fine and I can see the .h files when I type include but when I want to run my project I get the error undefined reference to ... for every method or attribute of Qwt library used!
What am I doing wrong here?
Windows 7: I have installed Qt 4.8.4 Win and Qt Creator 2.6.2 Win, VS2010 (from here). When I try to open a project (previously compiled with Qt 4.8.3 / Creator 2.5.2), it says I need a kit (no valid kit) and eventually I end up at Qt version is not properly installed. All is shown in the screenshots below.
I have checked some solutions:
SO QT version is not properly installed, please run make install is for Linux
Some say, I need to install Qt SDK, but where do I find this (this one contains older Creator / Qt versions), and what sense would the individual installers make if I need SDK?
Some say, I need to add Qt to path, but what exactly? Creator? The Qt 4.8.4, the qmake dir?
Somehow I fail with this make install, nothing happens.
I have installed the 5.0.1 including Creator 2.6.2 as one installation, this works. But when I then download 4.8.4. and try to add it as QT Version, same issue: Qt version is not properly installed
Any idea what I would need to do or install.
-- Edit -- List of trials ---
Added my Qt 4.8.4 and its qmake dir to PATH
Re-installed Qt in different order: Qt 4.8.4 first / Creator 2.6.2 thereafter
Opened Qt CMD Prompt qmake install (as in the suggestions): 4.8.4\install:1: Parse Error ('INSTALLING Qt Source Package Version 4.8.4.') Error processing project file: install
qmake install from Qt CMD. Runs 20 minutes, Laptop gets extremly hot, then it crashes
P:\Qt\Libs\4.8.4>qmake\qmake.exe install
QMAKESPEC has not been set, so configuration cannot be deduced.
Error processing project file: install
I had the same problem. Try to choose "qmake.exe" from the BIN folder, not the qmake folder, so in your case probably P:\Qt\Libs\4.8.4\bin\qmake.exe
Based on SO: How to install Qt on Windows after building? I eventually got to http://qt-project.org/doc/qt-4.8/install-win.html
Simply running configure solved it for me, I did not build, nothing else. The installer did apply several patches, so I still do not get why I have to run configure.
I succesfully build Qt 4.8 (without QtWebKit) on CentOS 5.8 (Qt Assistant and the demo's run fine). I also built Qt Creator 2.4.1 against Qt 4.8. I did not observe any errors during the process of building Qt Creator. However, when I attempt to run Qt Creator I receive the following error:
[root#localhost bin]# ./qtcreator
Cannot resolve 'dbus_get_version' in your libdbus-1.
Aborted
Has anybody encountered this error before? How did you fix it? Unfortunately upgrading to a better OS (such as Ubuntu) is not an option for me.
Thanks,
David
QtDBus module loads libdbus-1 library in runtime (via dlopen). That's why you don't have compile/link errors.
You can try either to upgrade dbus package (or whatever package contains libdbus-1.so) or use previous version of Qt.
(In Gentoo QtDBus-4.8 depends on dbus-1.2 and QtDBus-4.7.4 depends on dbus-1.0.2).
