[SOLVED] Unknown Symbol!

Mohammad Abdelhadi · 07-19-2010, 06:12 AM

Dear All,

My name is Mohammad Abdelhadi, I am working on research using a USB wireless card (WUSB600N) which works by a driver from Ralink (rt3572). In order to achieve my task, I am trying to modify that driver. One of the ways, I tried to call a function written in different module from that which I am working in. Every thing went fine (make & make install) until the modprobe command when i got (Unknown Symbol) about that function. I tried many ways to solve that problem like; Export_Symbol, and function pointers but, with no results!

Therefore, could you please help me in order to solve the problem of Unknown Symbol?

Thank you in advance..

Mohammad

How, exactly, do you think we can help you debug your code, without seeing it??
