[Freeswitch-users] Cross compiling freeswitch for raspberry pi

[Dušan Dragić]

Autotools is definitely a pain when cross compiling.
I'm probably gonna build it in a chroot (well systemd-nspawn, but same
thing) for now using qemu-arm-static, as Jeff and Ken sugested.
That is how I did it last time when I compiled FS for rpi (few months
back), but it's slow and I wanted to try cross-compiling it (and I'm
not giving up on this idea just yet).

I'm gonna compare config.cache between cross compile and native to see
if there are any glaring differences.

Did anyone have a chance to look at that backtrace, any ideas whats going on?

Also I found this wiki page:
https://wiki.freeswitch.org/wiki/Raspberry_PI-specific_documentation
It references a script
(https://github.com/bmanojlovic/rpi-cross-compile/blob/master/debootstrap_raspbian_chroot)
which seems to create a "mixed" chroot where the compiler is running
on x86 while everything else is running emulated with qemu.
At least that is what I think it does (by looking at the script),
haven't used it yet.
