I've just compiled a assembley file with nasm this way:
$ nasm -f elf somefile.asm -o somefile.o
After that I want to link somefile.o to a programm with gcc
$ gcc -m32 somefile.o -o someprogramm
But linking the file prints the following error:
ld: warning: ignoring file somefile.o, file was built for unsupported file format which is 
not the architecture being linked (i386)
Undefined symbols for architecture i386:
  "_main", referenced from:
     start in crt1.10.6.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
