Usage of CMake as a build system for a cocos makes the build process more universal and clear. Besides that it also has some implicit opportunities. Here I will describe how easy it becomes now to open a cocos2d project into Qt Creator IDE.
Setting up Qt Creator IDE
Qt Creator is a cross-platform (Windows, Linux, OS X) open source IDE currently maintained by Digia for Qt SDK. There is nothing special you should know about IDE installation process. Just download appropriate package for you system from official site.
Open cocos project into Qt Creator
Assuming that you have already installed IDE.
Step 1
Open it and follow: âFileâ -> âOpen File or Projectâ.
Step 2
Find CMakeLists.txt file of your project. And open it.
Qt Creator will ask for a build folder. I just leave the standard one.
Step 3
On the next window you need to just push âRun CMakeâ button
Step 4
At this point you already have opened cocos2d project into Qt IDE. Now you can launch it.
That is all for that tutorial. Thanks for your attention.
@Den
In the step 3, where is asks for âRun CMakeâ here are my errors as coming after running it:
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:

CYGWIN environment variable option ânodosfilewarningâ turns off this warning.
Consult the userâs guide for more details about POSIX paths: http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
cygwin warning:
â Configuring incomplete, errors occurred!
Please tell me what shall I be doing. I am trying to follow what is written in the errors but donât know how to fix what is asking.
Note: I am running it on Windows 8 and have installed cygwin.
What else should I do. I even included the cygwin/bin path in environments variablesâŚ
And also, are only those 3 to be installed. Anyways, Iâve installed all those that used to be required for cocos2d-x 2.2.2
Also, in the errors it is mentioned to add some path/variable which I am not able to understand how to do.
Please helpâŚ
Thanks for giving me tht link⌠Iâll try that and will tell you what happened.
Currently, I was having âQt 5.3.0 for Windows 64-bit (VS 2013, OpenGL, 636 MB)â from the link http://qt-project.org/downloads .
Also, can you tell me that in this what does âVS 2013â means in my install. I am asking because Iâve visual studio 2013, so do you knw if something is related to itâŚ
âVS2013â stands for Visual Studio 2013 compiler. That marks that this installation package contains pre-build binaries for that concrete compiler. As far as I know that package does not contains the compiler itself, whereas âMinGWâ version has a minimalistic version of MinGW.
Most of the build went Ok but im getting error [ 14%] Building CXX object cocos/audio/CMakeFiles/audio.dir/win32/SimpleAudioEngine.cpp.obj In file included from D:\dev\cpp\2d\cocos2d-x-3.1_mingw\cocos2d-x-3.1\cocos2d-x-3.1\cocos\audio\win32\MciPlayer.h:4:0, from D:\dev\cpp\2d\cocos2d-x-3.1_mingw\cocos2d-x-3.1\cocos2d-x-3.1\cocos\audio\win32\SimpleAudioEngine.cpp:30: D:/dev/cpp/2d/cocos2d-x-3.1_mingw/cocos2d-x-3.1/cocos2d-x-3.1/cocos/platform/win32/CCStdC.h:35:17: error: conflicting declaration 'typedef SSIZE_T ssize_t' typedef SSIZE_T ssize_t;

@Den
well after working on it , i dont understand how do you compile all the framework with mingw
and i explain :
first of all there are missing configuration in the CMakeList.txt , added with comment
`if(MINGW)
add_definitions(-DGLEW_STATIC)
add_definitions(-D__SSIZE_T) # add this line with it it not going to compile
endif()`
then the test-cpp canât compile Because of there are no libraries compiled for MINGW and there is no sources only headers
and of course it gives you linking errors:
Actually I have a Linux and use Qt Creator instead of Eclipse without any problems. I will figure it out for Windows and MinGW these days and give a feedback.
Hu you should say you compiled in Linux , for me when you say Qt and mingw its automatically cross platform .
any way . for windows using Qt 5.3 with mingw :
well you will have to compile the missing cocos2d-x external libâs in windows OS
and also add the: add_definitions(-D__SSIZE_T) # add this line with it it not going to compile
in the main CMakeList.txt file .
and also : ${CMAKE_CURRENT_SOURCE_DIR}/external/sqlite3/include
under include_directories( .... )
and also in CCConsole.cpp in line 197 , currently i comment out this but its problem with UNICODE i have to solve
CCConsole.cpp:197:107: error: cannot convert 'char*' to 'LPWSTR {aka wchar_t*}' for argument '4' to 'INT WSAAddressToStringW(LPSOCKADDR, DWORD, LPWSAPROTOCOL_INFOW, LPWSTR, LPDWORD)' if (WSAAddressToString((struct sockaddr*) &srcaddr, sizeof(struct sockaddr_in), 0, dst, (LPDWORD) &cnt) != 0) ^
the cocos2d-x lib compiles fine but now i try to ask the cocos2d-x team to post the sources of the external libâs and the way they compile them so i could compile the test-cpp
without success until now âŚ
I changed a dropdown box two times and selected back âMinGW Generatorâ after the second selection it seems to be working fine.
Anyway, I donât find how to build this for Android target. The CMakeList looks like it does only take into account linux, windows or mac but not android.
This is the output I receive after building the project
18:40:20: Running steps for project Cocos2dxâŚ

Sorry for the spam, i did not realize that the answer of the compilation errors was already there. It worked for me and I also have the issues with the externals libraries.
Still, I´m trying to figure out how to build this for android projects if it is not included in the build above. My idea is to combine QML with cocos2d it will be a very powerful platform for building graphics applications.
I found on possible approach to build android apps for android. Cmake does not support android natively so the way to go is a bit hacky. There is a web site with a walk through that explains how to build apps with cmake for android.
