Hi Laurent! I gave your working tree qemu-m68k [1] a try with sbuild today.
I configured the sources as follows: $ ./configure --target-list=m68k-linux-user --static Then ran "make && make install". Then created an m68k chroot using: $ debootstrap --no-check-gpg --variant=buildd --foreign --arch=m68k unstable sid-m68k-sbuild ftp://ftp.debian-ports.org/debian And copied the static qemu-m68k into sid-m68k-sbuild/usr/bin: $ cp -av /usr/local/bin/qemu-m68k sid-m68k-sbuild/usr/bin And tried to chroot into the m68k environment: $ chroot . qemu: fatal: Illegal instruction: ebc0 @ f67e66d2 D0 = 6ffffef5 A0 = f67fcf58 F0 = 7fff 4000000000000000 D1 = 0000010a A1 = 00000000 F1 = 7fff 4000000000000000 D2 = f6fff294 A2 = 00000000 F2 = 7fff 4000000000000000 D3 = 0000000f A3 = f67e1000 F3 = 7fff 4000000000000000 D4 = 00000000 A4 = 00000000 F4 = 7fff 4000000000000000 D5 = 00000000 A5 = f67fd000 F5 = 7fff 4000000000000000 D6 = 00000000 A6 = f6fff4e4 F6 = 7fff 4000000000000000 D7 = 00000000 A7 = f6fff274 F7 = 7fff 4000000000000000 PC = f67e66d2 SR = 0000 ----- Aborted $ I haven't figured out so far which instruction ebc0 is. I couldn't find it in any m68k documentation yet which I have skimmed through. Adrian -- .''`.
