c++ - Rcpp Windows 编译失败

Question

我开发了 Rcpp 代码并在 Linux 上编译，但我正在尝试 Windows。

我安装了 Rtools，并设置了路径，路径看起来是正确的。

> Sys.getenv("PATH")
[1] "C:\\Program Files\\R\\R-3.3.0\\bin\\x64;c:\\Rtools\\bin;c:\\Rtools\\gcc-4.6.3\\bin;c:\\MiKTeX\\miktex\\bin;c:\\Program Files\\R\\R-3.3.0\\bin\\;c:\\windows;c:\\windows\\system32;C:\\Program Files (x86)\\Intel\\iCLS Client\\;C:\\Program Files\\Intel\\iCLS Client\\;C:\\WINDOWS\\system32;C:\\WINDOWS;C:\\WINDOWS\\System32Files (x86)"

我安装了g++

> system("g++ -v")

Make也是通过Rtools安装的

> system("where make")
c:\Rtools\bin\make.exe

所以我不知道错误RcppExports？我尝试订阅 Rcpp-Devel 但遇到了麻烦。

这里是 Makevars.win

# Use the R_HOME indirection to support installations of multiple R version
PKG_LIBS = $(shell "${R_HOME}/bin${R_ARCH_BIN}/Rscript.exe" -e "Rcpp:::LdFlags()")
PKG_CXXFLAGS=`$(shell "${R_HOME}/bin${R_ARCH_BIN}/Rscript.exe" -e "Rcpp:::CxxFlags()")

我确实有 LinkingTo: 在 DESCRIPTION 中，但我不确定如何充分使用 LinkingTo

Answer 1

问题由:

Syntax error: EOF in backquote substitution

因为一个

`

在 Makevars.win 中最后一行的开头:

PKG_CXXFLAGS=`$(shell "${R_HOME}/bin${R_ARCH_BIN}/Rscript.exe" -e "Rcpp:::CxxFlags()")

将其切换为:

PKG_CXXFLAGS=$(shell "${R_HOME}/bin${R_ARCH_BIN}/Rscript.exe" -e "Rcpp:::CxxFlags()")

你应该是金色的。

顺便... You should switch over the LinkingTo: feature of Rcpp.因为这是非常老派的(老式 Rcpp？)链接方式。
