Fine, I followed this: https://www.netbsd.org/docs/guide/en/chap-build.html just with"i386" instead of sparc64 Also, it is not that different from what you and Maya suggested. I just update cvs src and then retried.. and now it apparently worked. It is compiling... now I only need to be patient to the kernel :) RIccardo

You can look at the /usr/obj/tooldir.NetBSD-8.99.1-amd64/bin/nbmake-i386 make wrapper script and check what does it set TOOLDIR too. I have this in mk.conf : CFLAGS+= -march=core2 CXXFLcoAGS += -march=core2 MAKE_JOBS = 3 could this affect cross-compilation? I hope not. What should build my 486 gcc? I suppose the run of "./build.sh -U -m i386 -u tools ", or not? Riccardo

Yes, it's full cross compilation.

TOOLDIR defaults to tooldir.${host_ostype}, so it reflects your os.

This is strange. Anything in your /etc/mk.conf or environment? You
can look at the /usr/obj/tooldir.NetBSD-8.99.1-amd64/bin/nbmake-i386
make wrapper script and check what does it set TOOLDIR too.

Re: cross-compiling kernel
./build.sh -U -u -m i386 kernel=CONFNAME doesn't work?
