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, ===== Best Regards, Park Lee __________________________________ Do you Yahoo!? Meet the all-new My Yahoo! - Try it today! http://my.yahoo.com
