【问题描述】:
我正在尝试使用 inline 库。
我尝试了http://adv-r.had.co.nz/C-interface.html 给出的第一个示例
library(inline)
add <- cfunction(signature(a = "integer", b = "integer"), "
SEXP result;
PROTECT(result = allocVector(REALSXP, 1));
REAL(result)[0] = asReal(a) + asReal(b);
UNPROTECT(1);
return(result);
")
我收到以下错误:
Warning message:

我从Rcpp 包中尝试了evalCpp("2+2"),它给了我4 作为答案。所以,我想编译器本身没有任何问题。这可能是什么问题?
我运行的是 Windows 7。我的sessionInfo 如下:

在另一台装有 Windows 7 的 PC 上尝试过,其中 R 安装在没有任何空格的目录中,并且最近安装了 R 3.1.0。所以这绝对不是因为R 路径有空格。

我终于得到了这份工作!需要将Rtools 目录添加到PATH。

我在我的 Windows 7 机器上遇到了完全相同的错误,但在一台正在运行的 debian 上却没有。
