I want to use the VAD module of webrtc, compiling on Cygwin. Cygwin has some packages for this: packages
I installed the selected packages and want to work out how to get things compiling. I've included what I've tried so far below. Am I taking the right approach to this? Or should I continue in a different way? I'm an amateur when it comes to c code.
main.cpp
int main() { AudioProcessing* apm; }
Compiling
$ g++ main.cpp main.cpp: In function ‘int main()’: main.cpp:3:2: error: ‘AudioProcessing’ was not declared in this scope AudioProcessing* apm; ^ main.cpp:3:19: error: ‘apm’ was not declared in this scope AudioProcessing* apm;
So I need to include some headers and link a dll to provide the implementation I'm guessing.
$ ls /usr/include/webrtc_audio_processing/webrtc/ base/ common_types.h system_wrappers/ common.h modules/ typedefs.h $ find / -name "*rtc*dll" /bin/cygsmartcols-1.dll /bin/cygwebrtc_audio_processing-1.dll /usr/bin/cygsmartcols-1.dll /usr/bin/cygwebrtc_audio_processing-1.dll
I found the header containing class AudioProcessing in audio_processing.h
main.cpp
#include "audio_processing.h" int main() { AudioProcessing* apm; }
Compiling
$ g++ main.cpp -o main -L/bin/ -lcygwebrtc_audio_processing-1 -I/usr/include/webrtc_audio_processing/webrtc/modules/audio_processing/include/ In file included from main.cpp:1:0: /usr/include/webrtc_audio_processing/webrtc/modules/audio_processing/include/audio_processing.h:22:35: fatal error: webrtc/base/arraysize.h: No such file or directory compilation terminated.
Sorry if this seems obvious, we all have to start somewhere.
Results of discussion:
The following resulted in a successful compilation of a trivial program using libwertc-audio-processing-devel on Cygwin.
$ cat main.cpp #include "webrtc/modules/audio_processing/include/audio_processing.h" int main() { webrtc::AudioProcessing* apm; } $ g++ main.cpp -o main -I/usr/include/webrtc_audio_processing/ -DWEBRTC_WIN -std=gnu++11 -L/bin/ -lcygwebrtc_audio_processing-1

the include directive is likely only
-I/usr/include/webrtc_audio_processing
