Changing VBR methods to CBR throws error

[NegiBaba]

Hello,
So I have been using another library that utilises vmsg for audio recording and since I have some issues with VBR audio file I needed a way to record audio mp3 in CBR, thankfully vmsg has those options.
What I did was fork this library and started development in my system and after modifying the VBR methods such as lame_set_VBR in vmsg.c and then using make to build the wasm file for it. But after doing so it's throwing errors which I can't see anywhere even tried logging and it never records.
Am I doing something wrong? I am new to this whole emscripten, clang and wasm stuff so won't be able to explain better.
