Hi again,

Spent quite some time chasing my tail on this in that if I change the 
path so  /opt/qtsdk-2010.02/qt/bin is at the start of my path, it stops 
the mysql classes working.

I have even tried taking the analogue clock widget example and building 
that with exactly the same result. ie it builds locally, the .so is not 
put anywhere else and the only way to get designer to see it is by 
coping the file which gives errors about headers.

So, would you be able to confirm:

1. *Should* the .so file be automatically put into a plugins directory?
2. If not, and putting it in manually, why am I getting errors. even if 
I put an absolute path to the relevant header file?
3. If 1 is true, what can be done to track down why that's not happening?

I can just live with creator not opening files is designer as I can open 
them manually there. It's a pain, but not terrible. IT would be nice to 
have that working without breaking mysql!

It's frustrating because I have a custom widget I really want to be able 
to drag on to forms in designer!

Cheers,

Rob
