[yocto] aarch64-oe-linux/bin/ld: cannot find -lgcc . Adding native build support for arm64/aarch64 in oe-rootfs.

[Jaggi, Manish]

It worked, thanks!!


But I couldnt find support to include multilibs say for 32bit and 64bit gcc.

There is a MULTILIB macro but I am not sure how to use it?

I think multilib recipes (bbfiles) are required, how to get them?

Manish Jaggi

You left out the development headers and libraries required to actually link.

IMAGE_FEATURES is a more efficient way of doing this.  EXTRA_IMAGE_FEATURES += "tools-sdk" will add gcc/cpp/make/etc, and "dev-pkgs" will ensure that all of the -dev packages are installed on your image, so you can link against anything you've installed.
