Compilation fail at pycryptodome for aarch64

Hi, LibreELEC devs,

I have successfully compile LibreELEC(32bit) for PineH64 successfully. It's running pretty well.

When I try building aarch64 version, it failed at pycryptodome:

Code

Error: unrecognized option march native

So do I have to edit the Makefile or something?

Or is there other recommeded way to modify CFLAGS for LibreELEC build system?

Thank you.

It's a known issue, but not a high priority for investigation as LE does not currently release aarch64 images (as we need arm userspace for libwidevine compatibility). If you build with ARCH=arm the image will complete.

Hi, Chewitt,

Thanks for the reply!

And thank you for reminding about missing widevine support for aarch64.

But please allow me to ask further 2 questions:

1. What if I wish to complete this build despite widevine support? Or at least complete building Kodi? Is there any official way to modify cflags?

2. In the completed ARM build, I wish to know what KODI did enable during its configuration. (opengl? libressl? alsa?... ) I can't find config.log in build/kodi-[0-9]* directory. Is there anyway to find out?
