[ptxdist] Using a different toolchain for certain packages

[ptxdist] Using a different toolchain for certain packages

[Guillermo Rodriguez Garcia]

Hello,

We have a BSP that uses an arm-linux-gnueabihf toolchain, and are
having some issues when compiling TF-A with the same toolchain.

While we managed to work around the problems that we found, we noticed
that the TF-A docs officially recommend using an arm-none-eabi
toolchain (https://trustedfirmware-a.readthedocs.io/en/latest/getting_started/prerequisites.html#toolchain).

Does PTXdist support using a different toolchain for specific packages?

Thanks,

Hello Guillermo.

I suggest not getting to hung up on compiler triplets. You'd be fine
compiling TF-A with something that has a OS/C-library interface, like
Linux. You can steer away your compiler from using that interface.

And yes, afaik, ptxdist supports different toolchains for various
packages. You can for example look on how the pre/kernel.make and
pre/bootloader.make do it. That would be the typical suspects.

I routinely add the selected_toolchain_kernel to my projects although it
has been a long time since I needed a separate one. It was mostly vendor
kernels stuck on _old_ stuff that wouldn't build with a newer compiler.

Regards,
Christian
