Hello, I try to build a cross-compiler for a Raspberry Pi. Information about my target machine: # uname -a Linux slackware 4.1.19+ #852 Mon Mar 7 14:35:56 GMT 2016 armv6l BCM2708 GNU/Linux # cat /proc/cpuinfo processor : 0 model name : ARMv6-compatible processor rev 7 (v6l) BogoMIPS : 2.00 Features : half thumb fastmult vfp edsp java tls CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xb76 CPU revision : 7 Hardware : BCM2708 Revision : 000e Serial : 000000005035c7ce # ./config.guess armv6l-unknown-linux-gnueabihf That's how I build gcc: $ ../gcc-5.3.0/configure --prefix=/usr --target=armv6l-unknown-linux-gnueabihf --with-cpu=arm6 --with-fpu=vfp --with-float=hard --enable-languages=c --with-newlib --without-headers --disable-shared --disable-nls --disable-libssp
The problem is --with-cpu=arm6 You may mean --with-arch=armv6
