Hello, Opus currently always sets default visibility for exported functions when OPUS_BUILD macro is set. However, it is not a desirable behavior when libopus is statically linked with the final binary (e.g. libxul.so in firefox), since all symbols get exported even with -fvisibility=hidden. In firefox, this problem is partially solved by wrapping translation units with #pragma visibility push(hidden), which is stronger than the command line flag, however, only libopus functions that are actually used in firefox code are affected, and others are still exported. It would be great if Opus provided some macro (like OPUS_STATIC_BUILD) that, when set, would make OPUS_EXPORT empty even when OPUS_BUILD is set. Can it be provided in future versions? -- Alexey Izbyshev
