求助,std::ve..如题,编译器为mingw,未使用cmake,其他都好好的,补充:vs2022中可运行,如果gcc实在不行,如何在vscode中设置与vs2022一样的环境(编译选项)呢
Rcpp::NumericVector result (n); for(int i = 0; i < n; ++i) { result[i] = something(); } return result; } 将此循环与OpenMP并行需要使用例如std::vector或RcppParallel::RVector,因为Rcpp向量不是thread-safe。对应的并行std::vector版本是 ...
