Shouldn't you be able to run $ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang-16 ~/bin/make.cross W=1 O=build_dir ARCH=hexagon SHELL=/bin/bash kernel/ after the command you just ran to reproduce this now? It is essentially the same fix that they mention above but for the second invocation of make.cross. You can also not even bother with the wrapper altogether if you have the compiler installed in the default path that they provide (W=1 is not necessary to reproduce this issue): $ mkdir -p build_dir $ curl -LSso build_dir/.config https://download.01.org/0day-ci/archive/20231116/202311160431.BXPc7NO9-lkp@intel.com/config $ make -skj"$(nproc)" ARCH=hexagon LLVM=$HOME/0day/llvm-16.0.6-x86_64/bin/ O=build_dir olddefconfig kernel/crash_core.o ... kernel/crash_core.c:554:3: error: call to undeclared function 'kexec_dprintk'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] kexec_dprintk("Crash PT_LOAD ELF header. phdr=%p vaddr=0x%llx, paddr=0x%llx, " ^ 1 error generated. > > Here you are.
