external function '_Z23transportEnc_GetLibInfoP8LIB_INFO' is missing

[MRITUNJAY GOUTAM]

Hello,

I am compiling fdkaac (https://github.com/nu774/fdkaac) with emscripten. This project uses libFDK-aac as shared library. 

Steps :

 Make project and libFDK-aac(shared) -  emmake make EMCC_FORCE_STDLIBS=1 EMCC_DEBUG=1 EM_BUILD_VERBOSE=3

Building project (LLVM bitcode)-  emcc project.o  libfdk-aac.o -s WASM=1  -s FORCE_FILESYSTEM=1 --preload-file ra.wav -o project.html --emrun --log_html -s FULL_ES3=1

But I got error :

error: undefined symbol: _Z23FDK_MpegsEnc_GetLibInfoP8LIB_INFO

error: undefined symbol: _Z23transportEnc_GetLibInfoP8LIB_INFO

error: undefined symbol: _Z24FDK_MetadataEnc_GetDelayP20FDK_METADATA_ENCODER

error: undefined symbol: _Z26FDKaacEnc_QuantizeSpectrumiiiPKiPKliS0_Psi

error: undefined symbol: _Z26transportEnc_EndAccessUnitP12TRANSPORTENCPi

Error in Javascript console :

external function '_Z23transportEnc_GetLibInfoP8LIB_INFO' is missing. perhaps a side module was not linked in? if this function was expected to arrive from a system library, try to build the MAIN_MODULE with EMCC_FORCE_STDLIBS=1 in the environment

error is saying side module was not linked. But I building it with bitcode of shared library. I think I am missing something which can link system library too, I am not getting how to do that.

Thank you,
