The 'make install...' failed and it took me some time to understand the reason. For the cross-compilation on the i386 system I have had to build like this: # cd /usr/local/acerC720/src # mkdir /usr/local/acerC720/obj-amd64 # MAKEOBJDIRPREFIX=/usr/local/acerC720/obj-amd64 # export MAKEOBJDIRPREFIX # make buildworld TARGET=amd64 TARGET_ARCH=amd64 # make buildkernel TARGET=amd64 TARGET_ARCH=amd64 If you later use the obj-tree on the bootet 64 bit system to install into the new disk, one must set the MAKEOBJDIRPREFIX to MAKEOBJDIRPREFIX=/usr/local/acerC720/obj-amd64/amd64.amd64 and all will be installed fine. matthias -- Matthias Apitz, guru@unixarea.de, http://www.unixarea.de/ +49-170-4527211 1989-2014: The Wall was torn down so that we go to war together again.
