What is wrong with my cross compiler?

问题

I am trying to compile a basic program that i can get to cross compile on my mac. I am running Mac OS X Mavericks. My cross compiler is arm-elf-gcc-4.7.3. I wrote a simple test program that looks like:

int main()
{
    ;
    return 0;
}

When I run /opt/local/bin/arm-elf-gcc-4.7.3 -o test test.c I receive these errors.

test.c:4:Unknown pseudo-op: .global
test.c:4:Rest of line ignored. 1st junk character valued 109 (m).
test.c:5:Unknown pseudo-op: .type
test.c:5:Rest of line ignored. 1st junk character valued 109 (m).

What is wrong with my cross compiler?

回答1:

Reads like the compiler spat out assembly the assembler couldn't read. Check for mismatches.

回答2:

The compiler was using the wrong assembler. I had to specify the prefix with -B/opt/local/arm-elf-
