[rtl] Unresolved symbols while running examples

[Vijay Subramani]

I have installed rtlinux 2.2a for Redhat linux 6.1 kernel version 2.2.12. When i tried to run the example programs after booting from the new RT kernel , it gave 'unresolved symbols' error. I recompiled the kernel from scratch after doing a 'make mrproper ; make menuconfig ; make dep ; make clean ; make bzImage'. Still the problem wasn't solved. Then I checked the System.map file that was generated when the kernel was compiled. It did not have the symbols that were reported as unresolved. Then I checked the kerenel_patch file. It did not have the definitions of these symbols (functions) either.   for example , the function 'gethrtime' was not defined in the patch file.   What should I do ?   Thanks in advance, Vijay Subramani.
