Ponyc: compile ponyc on rpi/raspbian stretch

[WoodyAtHome]

Hello,

I cloned and compiled ponyc on the current raspbian:
`
sudo apt-get install make gcc g++ git zlib1g-dev libncurses5-dev libssl-dev llvm-3.9 llvm-3.9-dev libpcre2-dev

export LLVM_CONFIG=/usr/lib/llvm-3.9/bin/llvm-config

make default_pic=true
`
The make stopped with an error. I had to change in the makefile line 48 to:
arch ?= native
tune ?= native

Then the ponyc was built and works fine here.

Good catch, I had a similar problem, but didnt follow it through tbh.

I think we should detect a raspian build and change the tune flag to native accordingly. Could you have a look on your raspian system how this could be reliably detected?
Maybe there is something we could use similarly to how we do it for other systems: https://github.com/ponylang/ponyc/blob/master/Makefile-ponyc#L1:L39

Maybe this helps:

@WoodyAtHome what is your output when running uname -s?

[WoodyAtHome]

pi@homeserver:~ $ uname -s
Linux

I got it working on my pi and will create a PR to update the makefile soonish.

Is there a full blogpost or tutorial somewhere with instructions to compille pony on an raspberry pi for beginners?

[SeanTAllen]

@nfuhs not at this time. what do you imagine would be a blog post beyond the sort of directions that are the repo README where the installation instructions are?

[nfuhs]

The installation instructions at https://github.com/ponylang/ponyc/blob/master/README.md#building-pony-on-non-x86-platforms are just a stub in my opinio.

I tried to run make on my raspi but only got an error message, I bet its my fault not setting up llvm to the right version

It would be nice if there are more details in the README howto setup llvm on Raspbian with the right version followed by the right make command.

[patches11]

Any update on this?

I can successfully build on raspbian stretch on a raspberry pi zero w, but any program I compile just says: Illegal instruction

[SeanTAllen]

@patches11 No one that I am aware of has access to the necessary hardware. A fix would need to come from someone with the environment who can debug it. Sounds like you are having a different issue however as you can build.

[aturley]

@patches11 can you verify that this is an ARM6? ARM6 is currently broken.

[patches11]

@aturley yes it was a Raspberry Pi Zero which uses the same SoC as the original Raspberry Pi the ARM1176JZF-S

I actually have a working ARMv6 branch just disabling the ASM, and I tried the update the ASM for ARMv6 based on some feedback, but didn't get it working, probably due to me not knowing ASM.

I will try to get my attempt together and comment on the new ARMv6 support issue when I get a chance
