如何在我的应用程序中使用voice_engine.lib？ [英] how to use voice_engine.lib in my application?

问题描述

大家好：

我在vs2008上构建了webrtc，并获得了voice_engine.lib。但我怎样才能在我的应用程序中使用它？我试过简单的#pragma comment（lib， voice_engine.lib），但链接时出现错误（未解析的外部符号），例如：

voice_engine.lib（dtmf_inband_queue.obj）：错误LNK2001：未解析的外部符号public：static void __cdecl webrtc :: Trace :: Add（enum webrtc :: TraceLevel，enum webrtc :: TraceModule，int，char const *，...）（？添加@ Trace @ webrtc @@ SAXW4TraceLevel @ 2 @ W4TraceModule @ 2 @ HPBDZZ）



我只是感到困惑，我有#pragma lib，有我吗？但是错误就发生了。



感谢任何回复！

Hi,everyone:
I have build webrtc on vs2008,and got the voice_engine.lib .But how can i use it in my application?I have tried to simply #pragma comment(lib,"voice_engine.lib"),but errors occur when linking (unresolved external symbols),such as:
voice_engine.lib(dtmf_inband_queue.obj) : error LNK2001: unresolved external symbol "public: static void __cdecl webrtc::Trace::Add(enum webrtc::TraceLevel,enum webrtc::TraceModule,int,char const *,...)" (?Add@Trace@webrtc@@SAXW4TraceLevel@2@W4TraceModule@2@HPBDZZ)

I just get confused ,i have #pragma the lib ,have i?But error just occurs.

appreciation to any reply!

推荐答案

似乎我已经获得了解决方案。

voice_engine.lib不是单独构建的，它依赖于它在许多其他lib上你也应该#pragma其他的libs，如果你想使用voice_engine.lib.Here是我的第一个简单演示，只是为了播放一个wav文件。

Seems that i have got the resolution.
voice_engine.lib was not built alone,it depended on many other libs.You should also #pragma other libs,if you want to use voice_engine.lib.Here is my first simple demo ,just to play a wav file.

//you also to include this debug.pb.h
#include "m:\WebRTC\trunk\build\Debug\obj\global_intermediate\protoc_out\webrtc\audio_processing\debug.pb.h"
#include "webrtc/voice_engine/include/voe_base.h"
#include "webrtc/voice_engine/include/voe_file.h"

#include <conio.h>
