qjpeg

I'm not running Windows, so some simpel check's:

Can you find qjpeg.dll or something in your Qt installation directory?
Have you something like QTPLUGIN += qjpeg in your pro-file?

Hi,

How are you trying to load .jpeg images in your application ?

Qt abstracts that part for you through QImage or QPixmap depending on your needs.

@SGaist I am using qimage and i always get this error when i use plugin jpeg. i dont know how to solve some suggestion?

SGaist

Are you trying to use a custom static build of Qt ?

If not then there should be no reason to have that error.

Can you share your .pro file ?

@SGaist Hi i think because i was using manual mingw 4.4.0 i am using the last now. I wanted to use this because i wanted to update some old project. Anyways i put the pro file but i think maybe it is the mingw is not well configured (for this i prefer last version). Pro file:

Do you also have a static build of Qt ?

omardavinci

@SGaist yes i built static libraries with command configure

SGaist

Did you build both the debug and release version of Qt ?
