Hi to you all, firstly I want to thanx a lot to help our 3days torturing of compiling qt

we are almost at the end of it, but our bitcoin-qt.exe wont launch, it just says "program bitcoin-qt.exe stopped working"
To make it work we had to change following first, to overcome ERROR:
I changed the set_vars.bat
@set BOOSTSUFFIX=-mgw46-mt-1_54
to
@set BOOSTSUFFIX=-mgw48-mt-1_54
changed 46 to
48, then procces continued further and both files were created succesfully
OK so heres what we got now:
bitcoind.exe is working fine
but bitcoin-qt.exe stops as said above
any idea?
thanks a lot
