Question

我一直在关注foobar2000组件的开发教程，但只用最少的代码就一直在构建错误。我的VS解决方案包括foobar2000 SDK中的这些项目：foobar2000_component_client，foobar200_SDK和pfc。

foo_playlists_tag.cpp：

#include "U:\SDK\Foobar2000-music-player\foobar2000\SDK\foobar2000.h"
DECLARE_COMPONENT_VERSION("Playlists tagger","0.0.1","About text here");
VALIDATE_COMPONENT_FILENAME("foo_playlists_tag.dll");

建立输出：

这些错误来自哪里？我该如何解决这些问题呢？

非常感谢任何帮助。

用户kode54在hydrogenaud.io找到了我的答案：

在Visual Studio 2010中，必须将所有依赖项直接添加到要尝试链接的项目中，作为引用。您可以在Common Properties，Frameworks和References下的项目的Properties对话框中找到引用列表。旧样式依赖项对话框似乎在Visual Studio 2008之后不能用于此目的。

感谢您的协助;帮我找到了lib文件。
