I don't have setenv (BTW do you know what package do i have to install in order to have it) installed on my freebsd system so i followed your advice and did : export TARGET=arm export TARGET_BIG_ENDIAN=t export TARGET_CPUTYPE=xscale (I am using bash shell) Target Arch is set correctly (arm) and BUILD_ARCH is i386, so i get the error about cross-build and the TARGET_ARCH set. What release are you using for your build ? If i am building a distro on an i386 machine for ixp425 (arm) what are the values for TARGET, TARGET_ARCH BUILD_ARCH and why can't i build the distro with the values i am setting (TARGET=arm, TARGET_ARCH=arm, TARGET?
