hi,
I am using Visual Studio 2010 with qt 3rd party libraries which belong to 4.7.0.0 (version as mentioned in the .dll files). I'm doing the following:
This always returned "true". So i compiled the same line using installed QtSDK and it returned "false", which meant it successfully read the jpeg file. After some analysis i realized that the problem was with the 3rd party qt libraries. QGuid4.dll was of version 4.7.0.0. I replaced this (and others since you must have all .dll's of the same version else it gives errors like "entry point not found...") with the SDK's 4.8.1.0 and the code compiled with visual studio worked fine too (returned "false"). But i'm required to use only 4.7.0 libraries.Qt Code:
qDebug() << "NULL?" << image.isNull();To copy to clipboard, switch view to plain text mode
<1> why this behaviour? what is lacking in 4.7.0.0 dll's (i need only gui,core and network dll's at the moment)?
<2> how should i proceed if i'm restricted to use only 4.7.0.0?
