Cross compile helloworld.c for powerpc

0 votes
500 views

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?

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.

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.

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.

I need to use microhttpd.a and pthread.a to build a cross-compiled program to be deployed on an arm-linux-gnueabihf device.

Where can I find instructions on how to do this? Or, is this simply a matter of downloading the source code and compiling (on a 64 bit UbuntuPC) to a library with my existing gcc-arm-linux-gnueabihf-4.8 cross-compiler?

While I may be able to find microhttpd.a and pthread.a binaries for an arm-linux-gnueabihf device, they will likely have been built with a different version of gcc-arm-linux-gnueabihf, which, I fear, could open up a can of worms.

how can I configure GCC to emit the calls to __cxa_thread_atexit() for destructor registration? On a Linux PowerPC target I see the registration of destructors, but not on the powerpc-rtems target. I guess I missed a configuration option or define. Has someone a hint for me?

I'm studying about C compiler for increasing software quality. So I want to get all of compile error message list of gcc about C language. I was trying to find it. But I can't find it anywhere. How can I find it?

Please help?

Is there a conditional define that expands to a string of the full gcc command-line used to compile the given .c/.cc file? I'd like to embed in the executable the exact compilation options used to build it.

I want to build a 'static toolchain', with option --disable-shared, for no shared library include/depend in the toolchain-self

cause I don't want the target binary runs depend on the toolchain, such as libc.so, ld-xxx.so.

But when the target binary need the function dlopen, it give a build error that libc.a need to recompile with -fPIC

So, how to compile glibc with -fPIC? or maybe I should ask is it possible to gen a shared library with
static toolchain?
