mac OSX Unknown pseudo-op: .type

问题:

I have to write some assembler code. Therefore I installed gcc4.4 (per homebrew) and called gcc-4.4 -c asma.s, but it does not work as expected:

asma.s:3:Unknown pseudo-op: .type
asma.s:3:Rest of line ignored. 1st junk character valued 97 (a).

The first lines consist only of standard pseudo-ops!

    .text
    .globl asma
    .type asma, @function
asma:

Do I have to install an alternative assembler?

回答1:

.type is an ELF/COFF directive, while OSX uses Mach-O format. In most cases you can safely remove the line.
