Dear Sanjeev,
Thanks for your help.
Now, I am building for omap5912osk, and we have a new board omap5912
based. I hope in some months changing my efforts to OMAP35.
Part of my .config file is listed below. The flag CONFIG_CPU_FREQ_TABLE
was set to "m", I changed to "y". I tried to compile again, but the
error still happening.
I took a look at .config after compiling and CONFIG_CPU_FREQ_TABLE got
back to "m" (automatically).
==== .config ===
#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=m
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=m
CONFIG_CPU_FREQ_STAT_DETAILS=y
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m
#
=============
After, i changed the flags CONFIG_CPU_FREQ_TABLE=y and
CONFIG_CPU_FREQ_STAT=y.
Then that error didn't occurred again, but another error happened:
====

Again, thanks for your help

Ramon,
Can you confirm if you have CONFIG_CPU_FREQ_TABLE=y in the .config?
The 'undefined' functions in your compile log are defined in drivers/cpufreq/freq_table.c
If you look at Makefile in the same dir, this file is included in compile based on the flag mentioned above.
Which platform are you building for?
Are you sure you haven't disabled CPU_FREQ manually?
If you haven't made any modifications the problem could be in the defconfig?
Though, I believe that cpu-omap.c may also need to be updated to take care of CONFIG_CPU_FREQ OR specifically CONFIG_CPU_FREQ_TABLE.
Best regards,
Sanjeev

Subject: Problems compiling kernel
Dear fellows,
I am facing some compiling errors in my kernel.
My kernel version is:
VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 27
EXTRAVERSION =
NAME = Rotary Wombat
And I updated the source using "git pull" today, before
trying to compile the kernel.
I got these errors:
MODPOST vmlinux.o
GEN .version
CHK include/linux/compile.h
UPD include/linux/compile.h
CC init/version.o
LD init/built-in.o
LD .tmp_vmlinux1

/home/ramon/work/linux-omap-2.6.new.teste/arch/arm/plat-omap/c

arch/arm/plat-omap/built-in.o:(.data+0x91c): undefined
reference to `cpufreq_freq_attr_scaling_available_freqs'
make: *** [.tmp_vmlinux1] Error 1
I looked in "plat-omap.c" and it calls the library cpufreq.h.
cpufreq.h has the prototipes of that undefined references and
cpufreq.c has the impementations of it.
So, I don't understand why it is happening. By the way, I am
a begginer in linux development.
Any help will be welcome.
