使用libwebrtc-audio-processing-devel的Cygwin编译程序

问题描述

我要使用在Cygwin上编译的webrtc的VAD模块.Cygwin为此提供了一些软件包:软件包

I want to use the VAD module of webrtc, compiling on Cygwin.Cygwin has some packages for this: packages

我安装了选定的软件包，并想弄清楚如何进行编译.我已经在下面列出了我已经尝试过的内容.我是否对此采取了正确的方法?还是应该以其他方式继续?我是C语言方面的业余爱好者.

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;
}

编译

$ 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;

因此，我需要包含一些标头并链接dll以提供我猜测的实现.

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

我在audio_processing.h中找到了包含AudioProcessing类的标头

I found the header containing class AudioProcessing in audio_processing.h

main.cpp

#include "audio_processing.h"
int main() {
    AudioProcessing* apm;
}

编译

$ 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.

抱歉，这似乎很明显，我们都必须从某个地方开始.

Sorry if this seems obvious, we all have to start somewhere.

讨论结果:

以下内容导致在Cygwin上使用libwertc-audio-processing-devel成功编译了一个琐碎的程序.

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

可能只有include指令

the include directive is likely only

-I/usr/include/webrtc_audio_processing
