Dear Mr. Andrew Gaul,
At present I am having the gcc version 2.96.81. When I searched on the web
for the egcs package, I found a update patch for gcc 2.96.81 that patch will
make the current version to 2.96.85. But after patching I am having the same
problem again. I don't know what is wrong with my work. Also, this tinme the
rtl.o is informing that it is having a unresolved symbol smp_config.. .
Tell me~, If I want to use Watch Dog timer, is it necessary to have LOCAL
APIC and I/O APIC. Because only when I enable these options in kernel
configuration I am getting into these problem
Regards
RD
