Hi!
I trying to install rtlinux-3.1 on kernel linux-2.4.4.
I folow the installation note and compile kernel and rtlinux
without any problem or error message!
But when i want to run "rtlinux start" appear this error:

   # rtlinux start
     /usr/rtlinux-3.1/modules/rtl_time.o unresolved symbol rtl-pritntf
     ...
     ...
   hint: you are trying to load a modules without a GPL compatible
         license and it has unresolved symbols.
         Contact the modules supplier for assistance,
         only they can help you!
   Scheme: (-) not loaded, (+) loaded
   (+) mbuff
   (-) rtl_fifo       
   (-) rtl_posix        
   (-) rtl_sched       
   (-) rtl_time
   
  
please tell me what is wrong in my installation?
