Message error 'C:/Program' not found with Rcpp

Question

I\'m running a 64-bit Windows 7 platform.

I have added to my installed programs/libraries:

• Rtools

• R (software)

• Rcpp

Answer 1

Following nograpes suggestion I get:

>> setting environment variables: 
PKG_LIBS =  C:/Users/ (...) /DOCUME~1/R/WIN-LI~1/3.0/Rcpp/lib/x64/libRcpp.a

>> LinkingTo : Rcpp
CLINK_CPPFLAGS =  -I"C:/Users/  (...)  /Documents/R/win-library/3.0/Rcpp/include"

28 : SEXP file47844fc6c7a( SEXP ns, SEXP xs ){

30 : int n = as<int>(ns);
31 : double x = as<double>(xs);
32 : for (int i=0; i<n; i++) x=1/(1+x);
33 : return wrap(x); 
34 : END_RCPP
35 : }
36 : 
37 : 

Compilation argument:
 C:/Program Files/R-3.0.1/bin/x64/R CMD SHLIB file47844fc6c7a.cpp 2>         file47844fc6c7a.cpp.err.txt 
Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
  cannot open file 'file47844fc6c7a.cpp.err.txt': No such file or directory

But, I admit that doesn't help me that much.

Answer 2

The R on Windows FAQ says in Question 2.2:

If you want to be able to build packages from sources, we recommend that you choose an installation path not containing spaces.

Also see Question 2.16 of that FAQ. I am fairly certain that we also make that point repeatedly in the Rcpp documentation.

Now, if you forgo the inline package, and try working in RStudio, then you might get around this (as there are more efforts to protect the $PATH with spaces).

But in short, I would reinstall R into, say C:\R\R-$version as it is the only way to get default behaviour on all examples. And we have lots of them. It's worth reinstalling.
