I am trying to compile and link a simple “hello, world!” program with GCC. This program uses the “printf” C function. The problem that I am having is that the terminal throws back multiple errors. I am running Archlinux, compiling with NASM, linking with GCC. Here is my code:<\/p>\n

; ----------------------------------------------------------------------------\n; helloworld.asm\n; \n; Compile: nasm -f elf32 helloworld.asm\n; Link: gcc helloworld.o\n; ----------------------------------------------------------------------------\nSECTION .data\n    message db \"Hello, World\",0\nSECTION .text\n    global  main\n    extern  printf\n\n    section .text\n_main:\n    push    message\n    call    printf\n    add     esp, 4\n    ret\n<\/code><\/pre>\n
The errors that I receive are as follows:<\/p>\n
\/usr\/bin\/ld: skipping incompatible \/usr\/lib\/gcc\/x86_64-unknown-linux-gnu\/4.7.2\/libgcc.a     when searching for -lgcc\n\/usr\/bin\/ld: cannot find -lgcc\ncollect2: error: ld returned 1 exit status\n<\/code><\/pre>\n
Can someone tell me what is causing these errors and what I need to do to fix them?<\/p>\n
Thanks in advance,<\/p>\n

    For such things, you should first understand what exactly gcc<\/code> is doing. So use<\/p>\n
     gcc -v helloworld.o -o helloworld\n<\/code><\/pre>\n
    and what is happenning is that you have a 64 bits Linux and linking a 32 bits object in it. So try with<\/p>\n
     gcc -m32 -v helloworld.o -o helloworld\n<\/code><\/pre>\n
    But I think that you should avoid coding assembly today (optimizing compilers do a better work than you can reasonably do). If you absolutely need a few assembly instructions, put some asm<\/code> in your C code.<\/p>\n
    BTW, you could compile with gcc -fverbose-asm -O -wall -S helloworld.c<\/code> and look inside the generated helloworld.s<\/code>; and you could also pass .s<\/code> files to gcc<\/code><\/p>\n<\/li>\n<\/ol>\n
