Cross-compiling apps #20

Open ronaaron opened 7 years ago

ronaaron commented 7 years ago

I'm interested in cross-compiling on my main Linux box. What I need is the appropriate sysroot to use (system-specific headers).

What is the best way to get a set of such headers for cross-compiling?

bamarni commented 7 years ago

Do you mean linux kernel headers? Starting from the latest release (2017-07-31), they should be available in /usr/include (cf. #10).

You mean in the running image?  Because I don't see them in the
  source tar.gz etc...

Maybe you can apply the principles explained here : https://community.arm.com/iot/embedded/b/embedded-blog/posts/cross-compilation-for-arm and https://resin.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/ to cross compile programs for aarch64 on x86 machines ?

You can find statically compiled qemu binaries here : https://github.com/multiarch/qemu-user-static

Yes in the running image, starting from 2017-07-31, or you can just grab them manually form here https://github.com/bamarni/pi64-kernel/releases (there is just the kernel / modules).

However I'm not sure if you need those or just cross compiling standard programs as shown by @farfeduc?
