Building a cross toolchain from scratch is an intricate process, it is not building just the compiler, you also need bintutils, C library headers and C library itself. Assuming you want Glibc for C library, try following procedure documented here: http://www.eglibc.org/cgi-bin/viewvc.cgi/trunk/libc/EGLIBC.cross-building?view=markup . Consider using one of pre-built cross toolchains, e.g., Linaro's. -- Maxim Kuvyrkov www.kugelworks.com
