Hi,

I am new to QNX...

When trying to compile the code provide in:
http://www.qnx.com/developers/docs/6.5.0/index.jsp?topic=/com.qnx.doc.io-pkt_en_user_guide/filtering.html


I got the following error:

There is an old thread about this issue, but there seems no final solutions:

Did I miss something in Momentics Project Properties settings? 

Thanks,
