I see a bug was opened for this but its not valid and this shouldn't be an issue. Keep in mind that an SDK contains all multilibs so "bitbake X-image -c populate_sdk" would be equivalent to "bitbake libXX-X-image -c populate_sdk" and be the same thing. One didn't work so we remove that. > Another issue,if I try to add lib32 packages to my x86_64 image > building the rootfs fails due > to such odd apt errors: > The following packages have unmet dependencies: > lib32-packagegroup-core-ssh-dropbear : Depends: lib32-dropbear but it > is not installable > lib32-packagegroup-core-x11-base : Depends: lib32-dbus-1 but it is > not installable > Depends: lib32-matchbox-terminal > but it is not installable > Depends: lib32-matchbox-wm but it > is not installable > Depends: lib32-mini-x-session but > it is not installable > Depends: > lib32-packagegroup-core-x11-utils but it is not going to be installed > Depends: > lib32-packagegroup-core-x11-xserver but it is not installable Unfortunately the debian backend is the least supported for multilibs and I suspect you'd have better luck with ipk or rpm. > Are there other possibilities? > Userspace can be pure i586, so full multilib support is not needed. > Having a x86_64 toolchain should be goof enough, it could build > userspace with -m32 and the kernel as-is. The system can definitely do it, its just not something we tend to do very often so its not entirely clear the best way to do it. What may work is selecting the i586 tune from an x64-64 target machine? Copying qemux86-64.conf to qemux86-64-2.conf and changing it to have DEFAULTTUNE ?= "i586" did appear to start to build at least in a quick test here...
