Hi, since people are mostly on vacation today, I offer an answer according to my latest information: Applications are built natively within the build-chroot. But not "on" the target, but for the target, using the target arch. > If, for any reason, this is not possibile, one has to cross-build the > applications. This is a wrong assumption. One can enter a cross-chroot and inside this cross-chroot, using binfmt support, target-arch tools can be executed "quasi natively" since the kernel passes execution to a qemu emulator. > Which approach do you recommend to set up the cross-build environment, in > order to make it work smoothly with Isar? > I am not an active Isar user and lack details, but I thougt this might help in meantime.
