I'm trying to compile linux kernel using this instruction: Running 64- and 32-bit RISC-V Linux on QEMU
My environment is macOS Monterey on M1, case sensitive APFS
riscv-gnu-toolchain building instructions:
arch -x86_64 zsh
./configure --prefix=/opt/riscv
make linux
After toolchain installation I've tried to build linux but got an error
make ARCH=riscv CROSS_COMPILE=riscv64-unknown-linux-gnu- -j 8
HOSTCC scripts/mod/file2alias.o
In file included from scripts/mod/file2alias.c:13:
scripts/mod/modpost.h:11:10: fatal error: 'elf.h' file not found
#include <elf.h>
^~~~~~~
1 error generated.
make[1]: *** [scripts/Makefile.host:112: scripts/mod/file2alias.o] Error 1
make: *** [Makefile:1193: prepare0] Error 2
Also I've tried to create symlink /usr/local/include -> /opt/riscv/sysroot/usr/include but got a new error:
make ARCH=riscv CROSS_COMPILE=riscv64-unknown-linux-gnu- -j 8
