I don't know what a .com file is, but you can use objcopy from binutils to convert between file formats. You could use objcopy to convert an ELF file into a binary file by using "-O binary" for instance. See the objcopy documentation. The binary file format may be what you are looking for.

If you want code without function calls, then you would have to write a C program without any function calls. Neither gcc nor binutils will help you there. -- Jim Wilson, GNU Tools Support, http://www.specifix.com
