Trying to run Julia on armv6l Arch-linux (Raspberry Pi)

[keyle]

Pardon my limited knowledge, but I'm trying to make Julia on my raspberry pi (mini server at home)

I get the following error:
Makefile:827: *** "unknown arch for openblas cross-compile". Stop.

Any help or tips much appreciated.

Never mind I just read carefully and it clearly says "x86/64 systems".

Ah well.

Thanks.

A port to ARM is something a few people have tried to look at, see #3134 - there are a few Makefile changes that ihnorton had to do for ARM. Also which LLVM version you use (see deps/Versions.make) can make a big difference to how far the compilation gets. Expect building LLVM to take a looong time.

We now build on ARMv7, but Raspberry Pi may be a generation older, that hasn't been tried yet.

I have a Gumstix ARM sitting on my desk that I think is ARMv6, not sure how to check. Would it be worth trying to turn on Ubuntu ARM builders on the PPA, for not-very-powerful ARM systems?

localhost:~/julia $ arch
armv7l

Good idea to turn on Ubuntu ARM builders on the PPA. Cc: @staticfloat

Also verified on Cortex A15. I do not fully understand the product naming schemes of various ARM manufacturers. /proc/cpuinfo is often helpful too.

According to http://llvm.org/docs/HowToBuildOnARM.html LLVM should build on ARMv6 too. So perhaps it is just a matter of trying and fixing a few things.
