Fix Compilation on ARM
It seems like -m64 is an x86 tag. See (compilation error cc: error: unrecognized command line option ‘-m64' in #40 ). This appears to be breaking ARM builds.
@LilyGinger could you add the following to external/geogram/CMakeLists.txt at line 41:
message("VORPALINE_PLATFORM: ${VORPALINE_PLATFORM}")
and then run python setup.py build and paste the output
Hi, @fwilliams Here is the output:

@LilyGinger I think something might be amiss. Did you paste the above lines in external/geogram/CMakeLists.txt around line 41? Your output should contain ON ARM CPU or NOT ON ARM CPU in the output. Can you run python setup.py clean before building?
Is there a solution to build on ARM systems that you have not documented here @fwilliams ?
From my understanding the problem comes from geogram, which (as you mentioned) has the -m64 tag that breaks the ARM build.
In the geogram repo they mention a way to make it work but I'm unsure on how to integrate it into this repository. Any suggestions?
https://github.com/alicevision/geogram/issues/19
Hi, yes it seems the problem is with geogram (geogram is also blocking builds on M1 macs).
I have a copy of geogram directly in the repo (i.e. not a CMake external project), so you can modify geogram's CMake directly to make it work. I don't have an ARM machine to test this on so I haven't done it. If you manage to get it compiling, I would love a PR. Also very happy to answer any questions/work with you to get this working!
I'm actually working on a Khadas Vim3 board (https://www.khadas.com/vim3). I will see what i can do to make it work. Any initial hints what I should look out for?
I think making a branch in the geogram cmake without the -m64 flag is a good start. Embree may also give you trouble but bumping the version should work. See the M1 Mac issue #42 which has more on that. Geogram had issues building on M1 Mac but that's just because the ifdefs for OSX assume Intel CPUs and include things like SSE headers. This shouldn't impact your case. Let me know if you run into any issues!
Geogram should indeed just have a switch for excluding the -m64 and -m32 flags on non arm builds and as you mentioned eigen is the next problem a build runs into. I am figuring that one out now and will let you know as soon as I found something. Maybe I'll come round the corner with a PR ;P
Thanks @Layer3! Did you embree instead of Eigen?
For both @brunovollmer and @Layer3, I created an arm branch which has the latest version of embree. If you can fix geogram, you can use that as the base for your PR.
Yea @fwilliams compiling geogram isn't the big issue for me, that is easily doable by adding a little cmake switchto exclude the -m64/-m32 flags. The bigger problem is that the CortexA73 doesn't play nice with sse, so now I'm currently stuck with this.

compilation terminated.
Up to this point I've just been deactivating sse where I could or adjust the asm calls if I had to, but this one feels just too wrong. Upside though. It's getting to 94% now : )
Hey @fwilliams,
I managed to compile point_cloud_utils on arm now. In the end I used simde to translate the sse2 calls that are used in igl to arm compatible instructions.
I'm now running into the issue that _pcu_internal is not found when I try importing the module.
Just wondering if you got any thoughts on this.
I have all my changes for this on a fork currently.
Thanks for this, I'd love to merge these changes into the repo!
Could you create a PR with your fork? That would help me resolve your issue.
Sure, I can clean them up some more and then PR them to one of the arm branches. Regarding the issue I still had. I am able to manualy import _pcu_internal from the build directory, so I think the pcu should be generally good to go still and it's probably just some confusion between the build and deploy configurations. Also I've seen that you already did some updates on the arm branches. I haven't used those as a base, so will have to merge that in first and confirm that everything still works.
Just to confirm that it runs, this is on a CortexA73

Amazing that it works!!!
I would ignore the current arm branch! I was messing around with updating embree but didn't really get anywhere. I'll delete it for now.
Hi @fwilliams, I am trying to install your repo. But I can't install using pip and source code.
Can you make a documentation about installation for M1 mac users? It will be useful for arm users. Thanks a lot and have a good day :)
Hi @BupyeongHealer thanks for posting here. There's currently an open PR which fixes M1 mac compilation #55 I'm going to try and merge this soon and cut a new release which works on M1 macs.
