undefined reference to `xilkernel_main'

I am usig xilkernel on microblaze spartan 3 board. I am getting an unusual
error that is

undefined reference to `xilkernel_main'

when i write the code below

int main (void) {
   print("-- Entering main() --\r\n");
   xilkernel_main();
   print("-- Exiting main() --\r\n");
   return 0;
}

Any idea what is wrong. I did configure input and output port (as RS232),
i am using timer1 as the sytem timer for xilkernel. I have statically
linked only two task using "software Platform Setting" in
'static_pthread_table' entry. There is no resource on this subject on
xilinx website. Please help.

Hello David,

I just ran into the same error the other day, and the reason I got the 
error was that the parameter MYAPP_LFLAGS in the file myapp_compiler.opt 
(in the __xps directory) wasn't set properly. It should be set to 
-lxilkernel in order to include the kernel when linking the code. (The 
same parameter should be set in the same way in the system_incl.make file)

Btw, I have had problems working with the Xilkernel in the XPS GUI. Not 
until I edited the make- and opt- and mss-files manually and compiled 
the applications in cygwin I was able to build the project properly. 
Hopefully this is fixed in EDK 8.1...
