If you're doing this on a pure64 system, you don't need to specify ARCH or HOSTCC. If you're running a 32bit kernel, you can't run 64bit binaries. So programs that have to run during the build process (like programs that do the menuconfig dialogs) have to be 32bit. -- #define X(x,y) x##y Peter Cordes ; e-mail: X(peter@cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!
