Can qt embedded still use png if it was not configured with -qt-libpng ?
-
I configured qt embedded without this options and when create an application with simple pushbutton i have no problem running it on my card but when i try add an icon to a push button (by using a resource file) the program don't work anymore (error SEGV). My program is static.
I can't find informations about -qt-libpng, this is why i did not put it in the configuration. i thought that simply displaying a image would not need it and that this lib would be to work (change colors, painting...) with them. -
Hi,
What configuration options did you use ?
What does a run through the debugger tell you ?If you don't specify that option, Qt will try to use your system's libpng.

I used the configuration :
./configure -embedded arm -no-armfpa -big-endian -qt-gfx-transformed -qt-gfx-linuxfb -nomake demos -nomake examples -no-svg -no-phonon -no-qt3support -no-feature-CURSOR -qt-mouse-tslib -L/usr/local/lib -I/usr/local/include -static
I can't currently debug because the board don't have a ssh server to connect with qt creator.
After searching in the board i don't think it has a libpng so i should be forced to use the one from qt i think.
EDIT : One error is solved but another appeared !
My segv error came from the way my ftp client was sending files to the board even when using a ubuntu pc and selecting "unix" server as target filezilla was thinking it was dos and was modifying some file. I am now using the simple ftp client of ubuntu and i don't have this SEGV error anymore, the application s running.
But the images are not loading "nicely", the colors are wrong. -
What board is it ?

How are the colors wrong ?
