我在名为PSM.cpp的文件中有一个cpp代码,如下所示,
#include <Rcpp.h>
// [[Rcpp::export]]
std::vector<std::string> useInitLists() {
std::vector<std::string> vec = {"larry", "curly", "moe"};
return vec;
}
当我获取以下代码时,我收到以下错误。
> Rcpp::sourceCpp("PSM.cpp")
g++ -m64 -I"C:/PROGRA~1/R/R-30~1.2/include" -DNDEBUG -I"C:/Users/30708/Documents/R/win-library/3.0/Rcpp/include" -I"d:/RCompile/CRANpkg/extralibs64/local/include" -O2 -Wall -mtune=core2 -c PSM.cpp -o PSM.o

make: *** [PSM.o] Error 1
Error in Rcpp::sourceCpp("PSM.cpp") :

有人可以建议错误的含义以及如何解决错误吗?谢谢。

您可以使用替代-std=c++0x
,但我从未在Windows上使用过g ++。
(很高兴它有帮助!)
