Why would ksyms show "console_drivers"
as "c02099a0 console_drivers_R__ver_console_drivers" ???????
I've done a "so called" "Upgrade" from Redhat 6.2 to Red Hat 7.0 and note
the following problems getting v3.0 pre8 installed and working.
After getting the rh 7.0 system installed, I downloaded a fresh 2.2.17
kernel package from www.kernel.org, compiled and installed it. It
required patching in kgcc in place of gcc to get it to compile. After
that, I copied the whole 2.2.17 source tree and created an rt-2.2.17 tree.
I patched rtlinux 3.0 pre 8 against this tree and got a fresh rtlinux
kernel which boots and the new kernel works normally. To get rtlinux to
compile I had to:
1) Modify the Makefile and change HOSTCC to kgcc and
CC to kgcc.
2) In the file: /usr/src/linux/include/asm/rtlinux_cli.h
remove all the stuff after the actual name in all #undef statements.
The stuff causes warnings, not errors, but are annoying. For example I
changed:
#undef __cli()
to
#undef __cli
and the warnings go away.
3) After you do a "make" there will be errors caused by the
"-mpreferred-stack-boundary=2" flag being set. The only way I found
get past it was to edit the file: rtl.mk and remove it from the
CFLAGS and the CXXFLAGS. The rtl.mk is automatically generated. It
wasn't clear where (in what file) the option was actually defined.
The compiler claims to be "egcs-1.1.2 release" by:
[root@vicki rtlinux-3.0]# kgcc -v
Reading specs from /usr/lib/gcc-lib/i386-glibc21-linux/egcs-2.91.66/specs
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
4) The insrtl produced:
[root@vicki rtlinux-3.0]# sh scripts/insrtl
modules/rtl.o: unresolved symbol console_drivers
modules/rtl.o: unresolved symbol __start_rtlinux_funcs
modules/rtl_time.o: unresolved symbol rtl_printf
modules/rtl_time.o: unresolved symbol rtl_rt_system_is_idle
modules/rtl_time.o: unresolved symbol rtl_request_global_irq
modules/rtl_time.o: unresolved symbol rtl_hard_enable_irq
....... and many more.........
In looking at the ksyms I got:
[root@vicki rtlinux-3.0]# ksyms -a | grep console_drivers
c02099a0 console_drivers_R__ver_console_drivers
[root@vicki rtlinux-3.0]# ksyms -a | grep __start_rtlinux_funcs
c01fd048 __start_rtlinux_funcs_R__ver___start_rtlinux_funcs
Anyone have any idea hoe to fix this?
