i work on windows environment, i have installed QT creator recently and wanted to execute a c program from .c file in QT. There are couple of problems why the file does not compile, first it does not recognize the library headers "time.h" "math.h" and even "stdio.h"
Two, i'm not sure if it will compile even after fixing the library, because i changed the include path in the .pro file to the path of the libraries. and still had a proble of compilation.
Is there a way, that the compiler knows that the file is .c instead of c++...how can i proceed.
Thank you very much
It sounds like you installed the IDE but not the SDK. The SDK comes with gcc and the standard libraries that you are referring to. If you need to use your own separate compiler, you can configure it in Qt Creator > Tools > Options > Build and Run > Tool Chains.
Some additional information may be found here for your issue:
http://www.qtcentre.org/threads/33974-Compiling-c-files-using-C-and-QT
So, my suggestion is to download the full SDK of Qt, and then pick and choose the elements you want, and make sure it includes a compiler.
Hope that helps.

Hi I have a debian image on BBB I have already installed QT creator on B^3 but the problem is whenever I try to start a new project in qt creator, couldn't see any option of kit. Infact when i add qmake and compiler path the application throws error.
What can I do to solve the problem. Can i directly get the full pack of SDK from qt.io/download ?
You must compile Qt libraries for your device (BBB) on your own, using specified compiler. You can find more information on this topic, here:
Qt Cross-Compilation Options
As soon as you compile Qt libraries for your device, you must move them to appropriate directories (on your BBB).
First, I would suggest learning to cross-compile, it's much faster & more easily maintained when you want to move to new versions. There's a ton of documentation and community around doing this. Windows & Linux both of which are probably dated, but info is still relavent. I've heard it's much easier from a linux host, but that could be biased.
That being said, if you don't want to cross-compile I believe you can simply install the qt embedded libraries. This question may offer some good advice. Once you have the libraries installed, you should be able to use qmake directly to create the Makefile for your project, then you can use cmake, or g++, etc.. to do the actual compiling.
You're likely going to work in command line though, I'm not sure you can run QT Creator on the BBB directly. I could be wrong.
I'm a beginner on open source world.
I can compile my own C++ code in VS 2015. but, I have little knowledge about compiling open source code. I can't even find a project file of that.
Anyway, I'd like to compile Sigil 0.9.4 version from source. My system is Windows 10 64 bit, and Qt 5.6.0 is installed. I've been looking for any basic guide for that but I haven't found yet.
I have downloaded a source code zip file from the link
https://github.com/Sigil-Ebook/Sigil/releases
And I have no idea what's the difference between Sigil-0.9.4-Code.zip and Source code (zip).
Which one should I download to compile?
Intuitively, I used 'importing project' in Qt but I get message 'no rule to make target all. stop'
Any instructions for that?
Thank you in advance!!!
For compilation you will need to use CMake. I recommend going through their web-site and read about it.
If you look at the source repository of the software you are trying to build (Sigil), you will see the root folder contains CMakeLists.txt. This is the file that will tell cmake program how to build and configure the software.
If you are planning to use Qt as your IDE, I recommend to download and install cmake first. Then make sure, Qt's toolchain is set up properly with the cmake. Then all you have to do is to open that CMakeLists.txt in Qt (see more details in the aforementioned link). Also, you can find plenty other tutorials on how to use cmake to compile your projects.
Hope this will help you get started.
I would like to use netbeans 8 for make QT applications. How ever, I have to specify the qmake file, which is for compiling QT apps. Is there any official source where I can get it? I tried google a lot, but haven't found any normal place. Thanks for the help in advance.
qmake is a program that compiles Project Files (.pro) into a Makefile. Think of it as "autoconf" of Qt world. To compile a Qt project, you only need to perform 2 steps,
run qmake to generate a Makefile from the Project File (.pro)
run make to build your application
netbeans.org has a step-by-step guide how do set things up,
https://netbeans.org/kb/72/cnd/qt-applications.html
qmake is a Qt specific replacement for the make utility, not a compiler. It is part of the Qt distribution actually... Just checked here, yes, it is part of the libqt4-devel package. Note that obviously you need the Qt development packages in addition to the runtime Qt packages.
trying to create a GUI for the first time.
I've decided to try QT 5.0, but it keeps giving me the error:
error: Qt Creator needs a compiler set up to build. Configure a
compiler in the kit options.
I go into kit options, and I can choose a number of different Visual Studio 11 compilers, or a MinGW compiler.
I have tried pointing the MinGW compiler to several different .exe files in the minGW bin dir, like c++.exe, gcc.exe, g++.exe, etc. I still receive the error message.
Then I read somewhere that I need to use MSVC10 to compile, however I can not find this compiler anywhere.
I just need to create a simple window with a couple labels and text boxes and a button, and I can't even get as far as creating a window.
Thanks for any help
I had to install MSVC2010, and use that compiler.
First configure a compiler in the "Compilers" tab of the "Build & Run" section in the Creator options. Then you can chose a configured compiler in a kit. Then set your project to use that kit.
Hello i'm a young develop on Qt. I want to know that can we convert project Qt (header, source, form, resource) to a file can run without Qt Creator? And how can we convert it to a file executable on window (.exe)?
The compiler is responsible for making an executable out of the source code. This has nothing to do with Qt.
When you start a program from the QtCreator an executable file is built by the compiler, then started. Have a look in your project folder to find that .exe file.
You dont have to do anything special. Each Qt project has a .pro file that is used for compiling. You need to use qmake on the command line with the .pro file as input. This will generate a makefile that you can then give to nmake.exe (if using Visual Studio compilers) or mingw-make (if you are uisng mingw compilers) to build. These steps will compile your source code into the .exe. Look through documentation of qmake to know more. Qt Creator also does the same steps and you can check out the buildlog in Qt Creator to see it working.
Yes, the exe file that you compile with Qt Creator or alternatively some other IDE or compiler is technically all you need to run the project from there on, except you need to have the linked Qt libraries somehow available to the executable. This is especially important if you plan to run it on a machine different from the one you developed it on. See the Qt documentation on Deploying Qt Applications for other details you may need to consider in that case.
