我正在尝试使用Armadillo矩阵库进行矩阵计算，它需要BLAS和LAPACK。 Armadillo文档建议从http://www.stanford.edu/~vkl/code/libs.html
获取预编译版本那里有.lib和.dll文件。唯一的问题是我不知道如何让Visual Studio（Express Edition 2008）识别这些文件。我尝试将它们复制到Visual C ++ include和lib目录C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\和C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib\，但它似乎没有做任何事情，因为当我尝试编译我的程序时，我得到了很多“未解析的外部符号“表示无法找到LAPACK功能的错误。

“Cell3DXT”，“TwoCell3DXT”和“ThreeCell3DXT”是我自己代码中的类。同样在上面的LAPACK和BLAS文件中，有“.exp文件” - 那些是什么以及那些与问题有关的事情？
答案 0 :(得分：2)
我找到了问题的答案。问题是我知道我必须将包含LAPACK .lib文件的目录放在库目录列表中（工具 - ＆gt;选项 - ＆gt;项目和解决方案 - ＆gt; VC ++目录 - ＆gt;库文件）但是忘记了我还必须将它添加到Project下的“附加依赖项” - ＆gt; （项目名称）属性 - ＆gt;链接器 - ＆gt;输入
