Somewhere in the changes over the last year or maybe longer, the KERNEL_CC option is no longer used to build the kernel. This bit me when trying to use a different GCC to test an issue, and finding genkernel still used: COMMAND: nice -n10 make -j10 -l8 ARCH='x86' AS='x86_64-pc-linux-gnu-as' AR='x86_64-pc-linux-gnu-ar' CC='x86_64-pc-linux-gnu-gcc' LD='x86_64-pc-linux-gnu-ld' NM='x86_64-pc-linux-gnu-nm' OBJCOPY='x86_64-pc-linux-gnu-objcopy' OBJDUMP='x86_64-pc-linux-gnu-objdump' READELF='x86_64-pc-linux-gnu-readelf' STRIP='x86_64-pc-linux-gnu-strip' HOSTAR='x86_64-pc-linux-gnu-ar' HOSTCC='x86_64-pc-linux-gnu-gcc' HOSTCXX='x86_64-pc-linux-gnu-g++' HOSTLD='x86_64-pc-linux-gnu-ld' Despite my attempts at KERNEL_CC in the config file, or --kernel-cc on the commandline. I'll try to bisect when it started happening later.
Are you sure? It's working for me (and it's required for compiling kernel with LLVM/CLANG for example: > >>> Started genkernel v4.2.3-git on: 2021-08-30 01:26:43 > * CMD_KERNEL_CONFIG: /proc/config.gz > *
