Problem with Qjson
-
Hi all!
I have problem with qjson library(from http://qjson.sourceforge.net). I downloaded sources and builded for symbian(like in instruction here http://qjson.sourceforge.net/get_it/symbian.html) without errors during building. Then I used qjson library for my project, build it(building is OK without errors) on device(sis-file was created normaly). BUT! When I install this file manualy and trying to launch, nothing happens. If I try to run from Qt, installing is ok, but when launching error "General OS-related error" only.
If I disconnect qjson library, and not use it, installing and launching normaly, all work...
Help who can!
Thx in advanceP.S.
I use Qt SDK 1.1 -
It may be caused by the certificate. How do you sign it?
-
I use self-signed certificate, but it does not influence in this case, without doubt. Same time ago I used qjson library with SDK 1.0 on my old computer, and everything was ok with the project,the device launched the application correctly(the certificate was also self-signed). Then I started working with new one, clean, without development environment, after installing Qt SDK 1.1 and building qjson library the problem occured=(

Could you please check what exact error did you get? This might be a clue to the solution because a list of all native Symbian error are available "here":http://symbian.newlc.com/Symbian-OS-Error-Codes.html

Could you try to install the sis file manually? After you finish the installation start the application and I guess the error message will be displayed on the screen.
Btw what device are you using? I just thought that the required Qt dependencies might not present on the device. If so you should wrap "your sis file with smart installer":http://developer.qt.nokia.com/wiki/Nokia_Smart_Installer_for_Symbian

This error can be caused by wrong capabilities or by stack size (rare, but possible).
-
I tried install manualy, of course, installation is ok, but when I launch app, nothing happens . No errors, screen not change.
About wrong capabilities..This project worked nice before, installed and launched well. I didn't change it. Yesterday I tried other projects, which has use qjson, and all are work equally - not launched. I do not understand what is the problem...

If it is interesting for anyone, I solved my problem. I used dynamic linking qjson library to the project like
@
symbian: LIBS+= -LC:\qjson\lib -lqjson
@
But after building qjson project, file qjson.lib is not created.(I can't find it on computer)
So I just copied this file from my old computer, and replaced linking on static:
@symbian: LIBS+= -LC:\qjson\lib -lqjson.lib@Thanks for all!
