 Posted: Wed Dec 27, 2023 8:32 pm Post subject: [Solved] Where is CONFIG_DEBUG_INFO_BTF? |
 |
|
I have a 6.1.67 kernel and am trying to work with libbpf which calls for a kernel built with CONFIG_DEBUG_INFO_BTF=y. A search in 'menuconfig' says the module is here ...
-> Kernel hacking
-> Compile-time checks and compiler options
-> Generate BTF typeinfo (DEBUG_INFO_BTF [=n])
But when I go there, I do not see the option. How else can I find a way to enable these options witin the kernel?

| If you press 'z' in menuconfig, it may appear and allow you to choose "Help" to show what depending option is missing preventing its selection. |

Hi,
Im interested in test of Extensible Scheduler Class, which requires this option too.
Am i correct, that option depends on CLANG as default C compiler? (CC_IS_CLANG) |
