[Savonet-users] Fwd: aacplus ocaml dynlink... how to tell if it's working?

[Matt C. <ma...@no...>]

Thanks... recompiling from source seems to have fixed that problem.

However, I've now found something new... it seems that whenever I compile
with fdkaac enabled, liquidsoap will immediately crash with 'Illegal
Instruction'.

I only need do 'ocamlfind remove fdkaac' then recompile liquidsoap and it
goes back to working fine...

Again, this is on the raspberry pi, using the libfdk-aac-dev:armhf
and libfdk-aac0:armhf from deb-multimedia.

Any ideas? Stack trace is below if that helps (partial)
