slackware arm 14.2 + mpd 0.20.5 compile error

tb404 · 02-27-2017, 02:32 PM

I cannot get MPD to compile on versions above 0.19.9.

This is what happens when i compile MPD 0.20.5 on Slackware ARM - 14.2:

Could it be something to do with soft float 14.2 ?

it seems something similar happens also elsewhere...

https://archlinuxarm.org/builder/in-...v5.log.html.gz

looking at their packages (search for mpd) they actually keep the soft-float version to 0.19.x...

tb404 · 02-27-2017, 04:59 PM

so do you think the latest versions of MPD will compile ok on Slackware Arm Current hard float?

ponce · 02-28-2017, 05:33 AM

yes, I just tried and it built fine on slackwarearm-current with just these modifications to the SlackBuild on SBo
