Linker Errors on Ubuntu 11.10

[GoogleCodeExporter]

Hi All,

I've experienced some strange behaviors while trying to compile r198 on Ubuntu 
11.10. 

After upgrading to Ubuntu 11.10 from 11.04, I faced to many linker errors while 
trying to compile SSL-Vision. I found out that the $QT_LIBRARIES variable in 
the CMakeList.txt points to wrong place, /usr/lib instead of currect 
/usr/lib/i386-linux-gnu/. This seems like a upgrade problem/bug.

I started again with a fresh install of Ubuntu 11.10 with all SSL-Vision 
required libraries installed. This time the $QT_LIBRARIES pointed to the 
correct place, however I receive this strange error while doing `make`:

Estou passando pelo seguinte problema, acredito ser similar 
utilizo o kubuntu versão:

Linux version 3.2.0-33-generic (buildd@batsu) (gcc version 4.6.3 (Ubuntu/Linaro 
4.6.3-1ubuntu5) ) #52-Ubuntu SMP

poderia ser problema de arquitetura este roda em 64?

Hello. Tim has applied a workaround for this back in Dec 2011, I believe he 
forgot to close the issue, so I'm doing it.

Cheers, Angelo
