Build for aarch64-linux

[rwilliams]

I'm keenly interested in having a working aarch64-linux build for IQ-Tree. It looks like there has been work done to getting it to work on the new M1 Macs (#42) If someone could point me in the right direction to get started I'd be happy to take a stab at this myself.

Cheers,
Ron

Dear Ron,
I have compiled a very initial build of IQ-TREE for M1 Mac by adopting "IQ-TREE : ARM NEON Implementation" by Joshlvmh. However, that initial build still needs further improvements.
For the implementation, you can have a look at the following commits:

• 44bfe3d
• 15195c8
• 748f436

The key idea is to detect the ARM architecture by #if !defined(__ARM_NEON) and implement the corresponding codes for that architecture.
I think you can try similar things for aarch64. Hope it help.
Cheers,
Nhan

@trongnhanuit Can you assign this to me so I don't forget I want to get to it :)

Hi all, I was just curious if there is an update on the aarch64 build?
Thanks!

Hi!
I've created a Pull Request that adds support for Linux ARM64 to CMakeLists.txt - #148
I also added CI based on Github Actions for Linux x86_64 and aarch64. You could see the results at my fork - https://github.com/martin-g/iqtree2/actions/runs/6768981048
The build for x86_64 is green but I'm still fixing the missing OS dependencies for the aarch64 one!

It would be great if linux-aarch64 builds could be enabled - bioconda recently added support for that. It would also be useful for arm docker images that can run without qemu on arm macs.
