Zhangjin, I cannot get this one to work, regardless of what I try:
$ make -j8 O=$PWD/output-i386 nolibc-test XARCH=i386 CROSS_COMPILE=/f/tc/nolibc/gcc-12.3.0-nolibc/i386-linux/bin/i386-linux- CC=/f/tc/nolibc/gcc-12.3.0-nolibc/i386-linux/bin/i386-linux-gcc (...) CC nolibc-test In file included from sysroot/i386/include/stdio.h:14, from nolibc-test.c:13: sysroot/i386/include/errno.h:10:10: fatal error: asm/errno.h: No such file or directory 10 | #include <asm/errno.h> | ^~~~~~~~~~~~~ compilation terminated.
I'll leave it aside for now as I've spent way longer than I hoped on these series. I could take the previous two patches however.
Thanks, Willy
