The command '/bin/sh -c ep /etc/network/interfaces' returned a non-zero code: 2

any idea what could be causing this?

Can you attach the config file(s) that ep is parsing?

[paolomemoli]

sure:

driver=${RADIO_DRIVER}
country_code=${AP_COUNTRY}
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=${AP_SSID}
hw_mode=g
channel=${AP_CHAN}
beacon_int=100
auth_algs=1
wpa=0
macaddr_acl=0
wmm_enabled=1
ap_isolate=1
ieee80211n=1

I dont think its to do with the file, its poping up the same error on every file, even files without any envs in.

I think its more to do with the Pi using being arm rather than x64/x86 - anyway to fix this?

[yawn]

Hmm - it's possible! Currently the release is not cross-compiled (or tested for that matter) for anything else then x64. Have you tried cross-compiling from source to linux/arm and using that? If this fixes your problem, I'll probably add gox to the project and provide a release for all possible platforms.

[paolomemoli]

that's a bit beyond me!

I'll have to look into a work around

[yawn]

I locally cross compiled ep for ARM 7 linux: ep-rpi.gz. Can you try that out and report back?

[yawn]

Any news regarding the custom build @memolipd ?

Sorry, been busy with other work. I will definitely give it a try when I finish my current project. Next week some time at the latest

I've released a RC for 1.0.0. Feel free to test and close if this fixes your issues.

[paolomemoli]

I wont be able to test the release, but as said above the binary works fine.

[yawn]

👍

[paolomemoli]

We're trying to run this on a Pi Zero but it fails due to the zero being a ARM and not ARM7.

Any chance someone can throw up a ARM binary? I've tried compiling the go code but its not easy!
