hello,
There was a compilation error....
-----------x--------------x------------------x-- MODPOST vmlinux.symvers MODINFO modules.builtin.modinfo GEN modules.builtin BTF: .tmp_vmlinux.btf: pahole (pahole) is not available Failed to generate BTF for vmlinux Try to disable CONFIG_DEBUG_INFO_BTF make: *** [Makefile:1183: vmlinux] Error 1
Is this a regression? If so, what commit caused this?
i did CONFIG_DEBUG_INFO_BTF=n in .config and then compilation was success.
Or you can install pahole, right? That's a requirement for that build option I think.
Looks like some distros enabled this option - either disable the option or install pahole. Not a regression.
Keep in mind that CONFIG_DEBUG_INFO_BTF is a dependency to build bpf tests. bpf build pulls kernel defines from BTF to generate a header file. Not desirable to generate header that conflicts with standard libgcc defines which is not relevant to this conversation.
thanks, -- Shuah
