Hi,
Now, I'm using FC2 (linux-2.6.5-1.358), for some
reason, I need to disable CONFIG_KALLSYMS for kernel
development.
In /usr/src/linux/.config, we can see that
"CONFIG_KALLSYMS=y" is included in the General setup
section like the following:
#
# General setup
#
CONFIG_SWAP=y
CONFIG_SYSVIPC=y
CONFIG_POSIX_MQUEUE=y
CONFIG_BSD_PROCESS_ACCT=y
CONFIG_SYSCTL=y
CONFIG_AUDIT=y
CONFIG_AUDITSYSCALL=y
CONFIG_LOG_BUF_SHIFT=17
CONFIG_HOTPLUG=y
# CONFIG_IKCONFIG is not set
# CONFIG_EMBEDDED is not set
CONFIG_KALLSYMS=y
CONFIG_FUTEX=y
CONFIG_EPOLL=y
CONFIG_IOSCHED_NOOP=y
CONFIG_IOSCHED_AS=y
CONFIG_IOSCHED_DEADLINE=y
CONFIG_IOSCHED_CFQ=y
CONFIG_CC_OPTIMIZE_FOR_SIZE=y
But, when we run 'make menuconfig', we can only see
that the General setup section only contains the
following items:
[*] Support for paging of anonymous memory (swap)
[*] System V IPC
[*] POSIX Message Queues
[*] BSD Process Accounting
[*] Sysctl support
[*] Auditing support
[*] Enable system-call auditing support
(17) Kernel log buffer size (16 => 64KB, 17 =>
128KB)
[*] Support for hot-pluggable devices
[ ] Kernel .config support
[*] Configure standard kernel features (for small
systems) --->
[*] Optimize for size
Then, It seems that there is no place to disable
CONFIG_KALLSYMS (i.e. turn 'CONFIG_KALLSYMS=y' to
'CONFIG_KALLSYMS is not set'), How can I turn off the
'CONFIG_KALLSYMS' item?? Is CONFIG_KALLSYMS=y set
automatically by system?
Thanks,
