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 也是由 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

问题给出者：

Syntax error: EOF in backquote substitution

因为

位于 Makevars.win:

中最后一行的开头

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

切换为：

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

你应该是金色的。

顺便说一下...You should switch over the LinkingTo: feature of Rcpp.因为这是非常老派的（vintage Rcpp?）链接方式。
