Recently lots of people asked me how to build QJson under Windows. Most of them reported build/link errors, so I decided to try personally.
The good news is that QJson can be successfully built under Window, I can show you proof 
I have written the build instructions on QJson website: just take a look here.
One last note: if you have problems with QJson please subscribe to the developer mailing list and post a message.

Hi,
in your documentation on QJson website is an error.
In the line ‘cmake -G “MinGw Makefiles” ..’ it is ‘MinGW’ not ‘MinGw’
Maybe you can fix it on the QJson website to save others some time
Steffen
Thanks, I fixed it.
Hi
The link to the windows build instructions returns a 404. Would you please take a look.
Thanks

Just follow these instructions. Make sure you execute step 5.
Hi,
I am getting the following
“CMake Error: CMake was unable to find a build program corresponding to “Visual Studio 9 2008″. CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: Could not find cmake module file:C:/Program Files/qjson/build/CMakeFiles/CMakeCCompiler.cmake
CMake Error: Could not find cmake module file:C:/Program Files/qjson/build/CMakeFiles/CMakeCXXCompiler.cmake

I supposed you were trying to build qjson using QtCreator. Have you tried to do that?
yes.. I tried that itself. But If I use the qmake then it shows the error like…
C:\qjson-0.7.1\qjson>qmake
‘qmake’ is not recognized as an internal or external command,
operable program or batch file.
I could not create qjson.pro file.. :’(
Please follow the instructions I liked right above. Just use QtCreator, do not use qmake from the command line.
Ok. I am trying that one. But where could I find the qjson.pro file. The pro file is not available in the qjson folder. Thanks in advance.
You can find them using latest version of qjson from git.
Hi,, Thanks..
I got the following files when I built the qjson.pro. (libqjson0.a,qjson0.dll,qjson.prl). and I used the following line import the qjson to my project…
INCLUDEPATH += “C:\qjson\src\include”
LIBS += “C:\qjson\build\lib\libqjson0.a”
Still I am getting the errors “qjson/parser.h:No Such file or dirctory”
“qjson/qobjecthelper.h:No Such file or dirctory”
I included the both header file in my one of the cpp file. Where can I make the mistake. Please assist me. Thanks in advance.
Your LIBS directive is wrong.
On the page I linked you there’s an example project for windows developers. Check out its .pro file.
Hi,,
Sorry… I used the following lines but I could not solve the error. :’(
INCLUDEPATH += c:\qjson\include
LIBS += -Lc:\qjson\build\lib -lqjson
Please help me. THanks in advance

Girija
Have you tried to build the example project? Does it work fine or do you get the same error?
No.. I could not build the sample. Project. I am getting the same error.
I’ll try to reproduce the issue. Right now I’m pretty busy (I’m moving to a different location).
Please send me a mail containing a list of sw you are using.
Hi Flavio,
I’m having problem in making QJson work on the actual Symbian device.
I followed the detailed build instructions in here: http://qjson.sourceforge.net/get_it/symbian.html
When I tried to install qjson.sis and cmdline_tester.sis to my n97 mini, I got “Request application Access not Granted” and “Update error” errors respectively.
I was able to run your sample qmake project (foo).
I created a “Mobile Qt Application” project to test the QJson on the phone.
It’s working on Qt Simulator, but when I switched the project target to “Symbian Device”, it could not start the application.
Here’s what I get in the Application Output
Executable file: 7696 2011-01-22T09:58:57 C:\NokiaQtSDK\Symbian\SDK\epoc32\release\gcce\udeb\qjsontest.exe
Package: 8316 2011-01-22T09:59:00 C:\Users\allan\workspace\Qt\qjsontest\qjsontest.sis
Deploying application to ‘Nokia N97 mini USB (COM4)’…
Copying installation file…
Installing application…
Starting application…
Could not start application: General OS-related error
Finished.
Hope you could help me with this.
Thanks in advance!
I completely followed the Qt Creator guide for compiling qjson, and I noticed that qjson does not have an include folder. is it supposed to make an include folder or something after compiling? what does INCLUDEPATH += …/qjson/include do if there is no include folder in qjson in the first place? doesnt that mean the code is looking for a header file in a folder which does not exist?

It works perfectly on simulator. but when we build smart installer sis file to Symbian devices, it occurs an error of Undefined Error of QJson::Parser~parser; and QJson::Serializer~serializer; i cant create my projects sis file.
Unfortunately I have no experience with symbian development.
Please send me a patch if you figure out how to fix that.
