對於我的MFC應用程序，我需要將數組中的.wav數據轉換爲ogg vorbis格式。將ogg vorbis編碼添加到我的項目
我將libogg和libvorbis編譯爲靜態庫。我在我的項目文件夾中創建了「bin」目錄，並在那裏放置了libvorbis_static.lib和libvorbisfile_static.lib。另外，我在bin目錄下創建了libvorbis文件夾和一個包含文件夾，並在其中放置了vorbis（帶有codec.h，vorbisfile.h，vorbisenc.h）和ogg（帶有os_types.h和ogg.h）文件夾。我將libvorbis_static.lib添加到我的項目的其他依賴項，並將bin文件夾添加到Additional Library Directories。
當我嘗試編譯，我得到的錯誤：

我很困惑。能否請你幫忙？ 謝謝。
