Arm support

Is there any chance for ARM/ARM64 support?

We have a couple of Raspberry PI around but as far as I know there is no "manylinux" equivalent for ARM.

If there is actually a need for it, we have the computer to do the build if needed. Which processor are you targeting ?

I'm personally trying to run on the rockchip OP1 processor, which uname -m identifies as aarch64 but I feel like that's missing some of the point, is there any way to make hdf5plugin compile on the client if it can't find a suitable pre-compiled version?

The OP1 has 2xA72 and 4xA53 cores. Compiling for the A53 is rather easy as I have access to raspberry pi and pine64 boards but none with A72 cores. By the way, how reactive is it ? is it usable as desktop computer ? Cheers, Jerome

With PR #18 being merged in master, hdf5plugin no longer embeds pre-built DLLs but instead build the filters from source with python setup.py build.
I haven't tested on ARM, but it should be possible to build it there now.
The possible issue is the embedded H5pubconf.h header file from HDF5 which is platform dependent.

We have an operational board in the office if needed...

@bamartin-ua
You can find a build in http://www.silx.org/pub/wheelhouse_arm64/
All tests have been passing.
Give it a chance. It was built on debian10 ... if our libc are compatible it could work.

@kif, thanks for the test!

Can this be closed? It is enough to specify where the HDF5 library is located to get the desired support.

The alternative is to provide the H5pubconf.h file used by @kif if we want to pip install from source.

The latest version builds out of the box on ARM and AARM64.

depends on your use. mine's in a chromebook and it's really snappy for what i need it for. takes a while to do any real work of course (which is why I need hdf5plugin, because gz compression is so slow). runs forever on battery though.

Thanks for all your help!
