GNU ld on OS X

Post by ehird »

Going through "BareBones", I saw I needed binutils. So, I installed it via MacPorts.

But it doesn't include gas or gld. I used the nasm version of the loader, but what about the ld script? "ld" on OS X is a Mach-O OS X binary thing, that works totally different.

I'm not sure why the package doesn't include them, actually.

Most people use a cross-compiled toolchain for OS development. (There's a section for binutils on that page)

Yes, sounds like a good idea. Though, a question - on a 2.16ghz core 2 duo cpu with 1gb of ram, will the gcc compile be a slow one? I imagine it'll take some time, but hopefully not too long...

That's what I did and it worked for me. Just download the binutils source and follow the instructions on the wiki...
Top three reasons why my OS project died:
  1. Too much overtime at work
  2. Got married
  3. My brain got stuck in an infinite loop while trying to design the memory manager
Don't let this happen to you!

On a 2.33 GHz Core 2 Duo with 2 GB of RAM, compiling GCC and binutils took maybe 15 minutes altogether, maybe less.

Yeah, it finished really quickly and works.

Now I'm trying to get a bootable floppy, just to make me feel as if i'm way further than I am ;)
