Question

我正在尝试使用SPAMS v2.6（从http://spams-devel.gforge.inria.fr/downloads.html下载），MATLAB R2018a和Win10下的MATLAB中的稀疏表示形式导入SPAMS工具箱。我已经用MinGW64编译了MEX文件。

当我运行compile.m时发生错误，似乎某些函数/模块（我不确定如何称呼它们）可以编译，而其他一些则不能。我试图评论那些导致错误的功能（约占全部功能的一半），其余功能运行良好，但它们无法通过SPAMS中的测试。我猜这些功能是交互的。

Answer 1

SPAMS随附的文件linalg/misc.h中，在文件顶部附近，有以下代码：

#if defined(_MSC_VER) || defined(_WIN32) || defined(WINDOWS)
#define isnan _isnan
#define isinf !_finite
#endif

这是错误的。 _isnan和_finite特定于Microsoft编译器。您正在Windows下编译（因此定义了_WIN32和WINDOWS），但是您没有使用Microsoft编译器，因此这些关键字不存在。

注释该块将使您可以使用MinGW编译器编译SPAMS工具箱。（或者至少可以防止您现在得到的错误...）

请注意，isnan和isinf是C99标准中定义的函数，对于任何现代编译器，都不必定义这些宏。

在Win10上为MATLAB编译SPAMS工具箱时出现错误“未声明'_finite'”
