RcppEigen包＆＃34; #pragma clang diagnostic pop＆＃34;警告

Question

尝试使用RcppEigen包时遇到了一些麻烦。我使用了发布here的示例。该功能起作用，但R产生了一系列类似的警告（如下例所示）。

In file included from example.cpp:1:
In file included from /Users/nguy2338/Library/R/3.4/library/RcppEigen/include/RcppEigen.h:25:
In file included from /Users/nguy2338/Library/R/3.4/library/RcppEigen/include/RcppEigenForward.h:30:
In file included from /Users/nguy2338/Library/R/3.4/library/RcppEigen/include/Eigen/Dense:1:
In file included from /Users/nguy2338/Library/R/3.4/library/RcppEigen/include/Eigen/Core:531:
/Users/nguy2338/Library/R/3.4/library/RcppEigen/include/Eigen/src/Core/util/ReenableStupidWarnings.h:10:30: warning: pragma diagnostic pop could not pop, no matching push [-Wunknown-pragmas]
#pragma clang diagnostic pop

那么，这些警告意味着什么，我应该如何处理这些警告？

Answer 1

解决方案是

#define EIGEN_PERMANENTLY_DISABLE_STUPID_WARNINGS
#include <Eigen/Eigen>
