It's referring to the DWARF version. Assuming you're compiling with gcc12, the kernel build is emitting DWARF 5 by default, which our libdwarf does not handle. Earlier this year I worked on extending libdwarf to support the new standard, at least well enough for ctfconvert's purposes. I'll try to get back to it shortly.help
