Common build errors

This page is supposed to give a summary of the most common build errors that are encountered when building Mumble and how to fix them.

Error message Description and fix
inlining failed in call to always_inline vdupq_n_f32: target specific option mismatch This error message occurs when attempting to build Opus. It seems to be an issue specific to the Raspberry Pi (4) (or maybe to ARM in general). This is a known problem in Opus.

It can be fixed relatively easy by specifying -DOPUS_DISABLE_INTRINSICS=ON when invoking CMake.
