Description

i´m trying to compile methods to access from javascript after, but some errors come up...

\celt\celt_decoder.c:110:26: error: static declaration of 'opus_custom_decoder_get_size' follows non-static declaration
OPUS_CUSTOM_NOSTATIC int opus_custom_decoder_get_size(const CELTMode *mode, int channels)

i don´t understand wht means...
I´m compiling from Windows using VSProj into win32 folder...
the command followed to compile is:
emcc ..\..\src\opus.c ..\..\src\opus_decoder.c ..\..\src\opus_encoder.c ..\..\src\opus_multistream.c ..\..\src\opus_multistream_encoder.c ..\..\src\opus_multistream_decoder.c ..\..\celt\celt_decoder.c ..\..\celt\celt_decoder.c -o WASM\opus_decoder.wasm -I..\..\include\ -I..\..\src\ -I..\..\celt\ -I..\..\silk\ -s EXPORTED_FUNCTIONS="['_opus_decoder_create','_opus_decoder_destroy','_opus_decode_float']" -DVAR_ARRAYS

Research direction

Reproduce the Windows emcc command from the issue and inspect the reported declaration in celt/celt_decoder.c. Check the command's duplicate celt_decoder.c input and the requested JavaScript exports; completion would require a confirmed WebAssembly build with callable exported methods, but the issue does not define a specific target change.
