Rcpp Windows Failed Compilation

Question

Я разработал код Rcpp, и он компилируется на Linux, но я пытаюсь открыть окна.

Я установил Rtools, и пути установлены, пути кажутся правильными.

> 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)" 

Я г ++ установлен

Так что я не знаю RcppExports ошибок? Я пытался подписаться на Rcpp-Devel, но у меня были проблемы.

вот 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()") 

У меня есть LinkingTo: в описании, но я не уверен, как в полной мере использовать LinkingTo

Answer 1

Вопрос задается:

Syntax error: EOF in backquote substitution

С

` 

находится в начале последней строки в Makevars.win:

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

Переключить его:

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

И вы должны быть золотыми.

Кстати ... You should switch over the LinkingTo: feature of Rcpp. Как это очень старая школа (vintage Rcpp?) способ связи.
