Btw, the latest riscv libc6-dev package is required, otherwise, we would also get such error: In file included from /usr/riscv64-linux-gnu/include/sys/cdefs.h:452, from /usr/riscv64-linux-gnu/include/features.h:461, from /usr/riscv64-linux-gnu/include/bits/libc-header-start.h:33, from /usr/riscv64-linux-gnu/include/limits.h:26, from /usr/lib/gcc-cross/riscv64-linux-gnu/9/include/limits.h:194, from /usr/lib/gcc-cross/riscv64-linux-gnu/9/include/syslimits.h:7, from /usr/lib/gcc-cross/riscv64-linux-gnu/9/include/limits.h:34, from /labs/linux-lab/src/linux-stable/tools/testing/selftests/nolibc/nolibc-test.c:6: /usr/riscv64-linux-gnu/include/bits/wordsize.h:28:3: error: #error "rv32i-based targets are not supported" 28 | # error "rv32i-based targets are not supported" The glibc commit 5b6113d62efa ("RISC-V: Support the 32-bit ABI implementation") fixed up above error, so, glibc >= 2.33 (who includes this commit) is required.
