c++ - 英特尔DAAL 2017 Beta更新1编译错误

Question

我正在努力使daal在我的项目中工作，现在遇到了以下错误-我正在努力理解它，甚至不确定从哪里开始调试。

我正在尝试复制此网站的代码:https://www.codeproject.com/Articles/1151606/Lightning-Fast-R-Machine-Learning-Algorithms，但在Windows 10中使用以下软件(完全按照该网站):

英特尔DAAL 2017 Beta更新1

R版本3.3.1(错误提示)

Rcpp软件包版本0.12.5

内联软件包0.3.14版

e1071软件包版本1.6-7

我已经完成以下工作:

将Dal软件包从C:\ Program Files(x86)\ IntelSWTools \ compilers_and_libraries_2017.1.143 \ windows \ daal \ include复制到R的包含

遵循https://software.intel.com/en-us/get-started-with-daal-for-windows

我按照Ralf的建议对csv路径进行了更改，并将以下内容插入了Makevars.win文件中:

Answer 1

需要使用您使用的Rcpp::as函数在R内部数据类型(SEXP)和普通C++数据类型(int，string，...)之间进行转换。当您将参数从R传递到C++函数时，这是必需的。由于您在C++代码中指定了参数，因此不需要此函数。以下应该在readCsv函数中起作用:

std::string fname = "C:/Users/Documents/BAJAJ.csv";
int k = 7;

或者，您可以坚持使用教程中从R传递这些参数的版本。

顺便说一句，您不需要将/加倍。仅\具有特殊含义，必须加倍以引用文字版本。
