Question

我需要使用一些音频功能来编译INET。我正在将Omnet ++ 5.1与INET 3.5.0一起使用。从audiofile 0.3.6包中，我添加了2个需要的文件audiofile.h和aupvlist.h 现在，当我构建它时，缺少函数afWriteFrames' afInitSampleFormat'等。应在libaudiofile.dll中定义此函数。我的问题是如何从dll中获取功能？

我将路径添加到库libaudiofile.dll，但Omnet不想使用这些功能。我试图将libaudiofile.dll复制到Windows \ System32和SysWOW64，但没有任何效果。还是一样的错误。

在文本编辑器中打开src/makefrag，然后在末尾添加：

LIBS += -L/c/libraries/audiofile  -laudiofile

假设libaudiofile.dll在C:\libraries\audiofile中。
