On Ubuntu: 1. mount the RaspberryPi SD card image partition 2 on /mnt decide a better directory later 2. Run the script #!/bin/sh ## ## build the object file arm-linux-gnueabihf-gcc-4.6 -c \ -nostdlib -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard -marm -Wl,-t \ hello.c -o helloc.o ## ## link arm-linux-gnueabihf-gcc-4.6 -o helloc helloc.o \ -nostdlib -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard \ -marm -Wl,-t \ /mnt/usr/lib/arm-linux-gnueabihf/crt1.o \ /mnt/usr/lib/arm-linux-gnueabihf/crti.o \ /mnt/usr/lib/gcc/arm-linux-gnueabihf/4.6/crtbegin.o \ /mnt/lib/arm-linux-gnueabihf/libgcc_s.so.1 \ /mnt/lib/arm-linux-gnueabihf/libc.so.6 \ /mnt/usr/lib/arm-linux-gnueabihf/libc_nonshared.a \ /mnt/lib/arm-linux-gnueabihf/ld-linux-armhf.so.3 \ /mnt/usr/lib/gcc/arm-linux-gnueabihf/4.6/crtend.o \ /mnt/usr/lib/arm-linux-gnueabihf/crtn.o \ /mnt/lib/arm-linux-gnueabihf/libm.so.6 This produces an image that will execute on the Raspberry Pi. There seems to be a problem with either the crtxxx.o files or the libs. Where do I file a bug report? Tom Dean
