Can't build demos and examples
Hello, I just installed Qt and wanted to try some examples. I couldn't build many of them. I use Windows 7 and I built for Desktop. I got these errors from Affine Transformations, Arthur Plugin:
@:-1: error: cannot find -ldemo_shared
:-1: error: collect2: ld returned 1 exit status
Plug & Paint gave this:
@:-1: error: cannot find -lpnp_basictoolsd
:-1: error: collect2: ld returned 1 exit status@

Please disable the "shadow build"
It didn't work. Still same errors.
Is there anything else I can try?
you are running in debug mode, try in release mode
Still no luck. :(
one more bump, really want it to work :-)
soo any clues why it misbehaves?
