Cross compile helloworld.c for powerpc

Question

I'm running Ubuntu 13.04 on an intel machine and I want to cross compile helloworld.c so that the resulting binary will execute on Ubuntu on a powerpc machine.

So something simple like:

gcc helloworld.c --target powerpc-linux -o helloworldppc

But the answer seems to always come back how to cross compile gcc itself...

Doesn't Ubuntu have a crossbuild-essential-powerpc package?

Answer 1

I have done for freescale board. you have to install power-pc compiler in your linux machine. you have to export PATH=$PATH:"path of powerpc-linux-gcc" in your linux machine. then you have to give command powerpc-linux-gcc file.c.

Answer 2

You need a cross compiler. The target is fixed when GCC is built, so you cannot use a GCC built for the intel target to build binaries for the powerpc target.

Answer 3

Of course, you're going to need an Ubuntu x86 -> powerpc cross compiler. Before we go through the steps of building one, please make sure that you can't get a packaged cross-compiler from someone else.

Once you have done that, we can show you how to build a cross-compiler. But be warned: it takes a fair bit of C and operating system experience, and you'll need to allocate a fair bit of time.
