我有一个长期项目正在进行中,其中涉及构建一个可以产生新颖音乐和声的专家系统。我从 VB.net 开始,到目前为止,我想使用独立于平台的语言,所以我转向 C++ 以促进未来的迁移。本质上,音调是原子,它们在分组为向量时形成和弦进程的一部分,当作为向量分组时形成块等的一部分。所以整个结构对它有一种递归的感觉。尽管以下代码将在 Netbeans 7.2 中编译和链接,但我遇到了难以解决的严重内存问题,所以我现在使用 Eclipse。虽然动态库将在 Eclipse 中编译,但总体上似乎存在链接问题,因此没有创建对象。我已经花了几天时间尝试各种补救措施。我在这里包括顶级主代码和我收到的错误消息的部分列表。任何有关可能发生的事情的指示将不胜感激。期待中的Thx..

您只提供搜索要链接到的库的路径。您还需要提供库,使用-l. 例如,对于libFoo.so使用-lFoo.
