mesa-20.0.6 fails to build on Raspberry Pi 4

[NeilMunday]

I was working in tweaking the mesa-20.0.6 package for debugging purposes, but it does not build (even without my tweaks).

If you need more info, please let me know.

Builds fine for me. How are you building? With devtools-alarm I trust.

[NeilMunday]

Thanks for the reply.

I was building the package on my Raspberry Pi 4 using:

$this->bbcode_second_pass_code('', 'makepkg -A -s')

I've since updated all the packages on my Raspberry Pi and tried building the package again and now it works. I'm not sure why it is working now but it is.

I haven't been using "devtools-alarm" package, is this intended for use on a x86_64 host to create an Arm based chroot to build the packages under? Is there a guide on how to use the tools provided by this package? I tried to find one but I've not had much success.

At the moment I build the packages on my Raspberry Pis and use distcc to speed up compilations.

Thanks for your help,

Neil.

See the devtools wiki page. Intent is to build in a clean environment for the native architecture, not to cross compile although you can use distcc to speed-up. I wrote a helper script I use for this: https://github.com/graysky2/buildhelper but it is optional and somewhat specific to my needs.
