Linux Build Issues When Using alembic in own project

[GoogleCodeExporter]

I'm getting a lot of linker error using Qt / qmake. The project works under mac 
fine but under linux I'm getting the following errors (g++ 4.4.3 ubuntu 10.4 
lts )

There are lots of other linker problems most of which seem to be for the dtors 
what am I missing as I presume it's some sort of g++ flag to do with virtual 
methods etc? 

I've attached a full output of the error messages

cheers

I've actually fixed it now, seems I needed to add both the .a files and 
-llAlembicAbc etc not sure why this is the case under linux and not Mac OSX but 
I presume it's something to do with g++ / qmake. The solution in the qt project 
file is as follows incase anyone else has these issues
