Cross compile for ARMv7

[lecndav]

Hi,

is it possible to compile a program with e.g. random forest classification for ARM architectures?

@lecndav Did you get this library working on ARM?

[lecndav]

@debugaftercoffee Yes, got it running on a raspberry pi

@lecndav Can you share how you got it to cross compile? I'm on Mac trying to build for ARM. When I try to cross compile for ARM or set CGO_ENABLE=0 I get the error associated with 270. From what I can tell the first reference to a C reference causes the build to fail. Any pointers you have would be greatly appreciated.

@debugaftercoffee The main problem, I think, was with OpenBLAS. I had to install Fortran and needed to compile a lot packages and dependencies manually. But I can't remember the details. It was not suitable for me because the performance was bad.
