Building on Linux on ARM64

[k8ieone]

Is aarch64 Linux ever going to be supported like with Embree? Or is it never going to happen like with OpenImageDenoise?

Right now building openpgl on ARM fails. I have attached the error.
build.log

@a13xie could you give us a little bit more information of your arm-based system?

[k8ieone]

Sure thing, sorry I didn't go more detailed in the first place.
It's Arch Linux ARM running in a Docker container. The host that the container runs on is x86, but uses qemu-user-static to emulate ARM.

You are apparently affected by RenderKit/embree#410

TLDR: add "-flax-vector-conversions" to your CXXFLAGS

[k8ieone]

@StefanBruens Thank you so much! Indeed using -flax-vector-conversions while building OPGL seems to fix this.

Should I close the issue?

[sherholz-intel]

@a13xie wait with the closing for the next point release.
I will add this flag with some others.

@StefanBruens thanks for looking up a fix and pointing it out.

Hi @a13xie ,

could you try and see if the fix/linux-arm-and-visibility branch fixes your problem?

Will do!

[k8ieone]

@sherholz-intel I can confirm that building from the fix/linux-arm-and-visibility branch doesn't require manually adding the -flax-vector-conversions flag anymore.

Thanks for testing. This fix will be included in the next release.
