What do you mean by "plain binary"? From the context, it looks like you want some sort of stand-alone executable but you don't say how you intend to run it. >But I give linker error like a "undefined reference to putchar" This implies that you have a reference to putchar() in foo.c - you will need to provide an implementation of it and the implementation will (of necessity) require knowledge of the execution environment. >ld -Ttext 0x0 -e main -s --oformat binary -o foo.bin foo.o -lc This won't work because libc in intended to work in an environment hosted on FreeBSD and needs infrastructure that is part of crt*.o Have a look in (eg) /usr/src/sys/boot/i386 for code that is intended to run without the kernel. -- Peter Jeremy
