Building 1.2.1 for Windows using mingw yields error: Undefined reference to read_wav...

[zorlack]

I'm following the instructions in #168 but with version 1.2.1 I can no longer compile successfully:

I start in a fresh Debian container and I prep it by doing:

apt-get update -y
apt-get install git curl build-essential g++-mingw-w64-x86-64-posix gcc-mingw-w64-x86-64-posix -y
git clone -b v1.2.1  https://github.com/ggerganov/whisper.cpp.git

Now I go to do the build

root@3fc79d49a589:/# cd whisper.cpp
root@3fc79d49a589:/whisper.cpp# mkdir bin-windows
root@3fc79d49a589:/whisper.cpp# mkdir bin-windows/models
root@3fc79d49a589:/whisper.cpp# cp ./models/download-ggml-model.sh bin-windows/models

I'm not sure what's happening here. Seems like it doesn't see a reference, but I'm not sure what's changed.

This process works just fine for v1.2.0

Thanks very much!

There's a new file in "examples" named "common.cpp" in this version.
You need to build this file also.
x86_64-w64-mingw32-g++-posix -I. -I./examples -O3 -std=c++11 -lwinpthread -c examples/common.cpp -o common.o
And add the "common.o" to build "main.cpp".
x86_64-w64-mingw32-g++-posix -I. -I./examples -O3 -std=c++11 -static-libgcc -static-libstdc++ -lwinpthread examples/main/main.cpp common.o whisper.o ggml.o -o main

Thank you! @lijihhh you're exactly right.

@lijihhh Running the main.exe after building it this way doesn't yield any results
I'm not sure what I'm doing wrong

[lijihhh]

Which cpu are you using？My E5 cpu can't print any results either. But it works correctly on my i3 PC.

I'm using an i7-4700MQ

I'm getting the same error when building on Ubuntu 22.04 on WSL2, even after compiling common.cpp and adding it to main.cpp
