How do I compile this LLVM ASM?

I'm just trying to play around with LLVM to figure out how it works. I'm trying to compile the following snippet:

;hello.ll
@.LC0 = internal constant [4 x i8] c"%d\0A\00"

declare i32 @printf(i8*, i32)

define i32 @main() {
       %cast210 = getelementptr [4 x i8]* @.LC0, i64 0, i64 0
       %result = add i32 1, 4
       call i32 @printf(i8* %cast210, i32 %result)
       ret i32 0
}

If I try to compile it with llvmc, I get the following:

% llvmc hello.ll
ld: in /tmp/llvm_1291dX/hello.o, ObjectFileAddressSpace::mappedAddress(0x54) not in any section
collect2: ld returned 1 exit status

If I compile it to bitcode and run llc and gcc on it, I get the same thing:

% gcc -v hello.s

However, if I JIT it with lli, it works:

% lli hello.bc
5

What am I doing wrong?

It turns out that I'm running 32-bit LLVM and 64-bit gcc. If I run gcc like this it works:

gcc -m32 hello.s -o hello
