R help - Jul 2011 - inline/Rcpp: Problem with space in path under Windows

I am trying to run inline/Rcpp under Windows 64. The RTools are installed on
a spaceless path D:\rtools.

Inlining pure c-code works perfectly. When I try the sample code for cpp in
the cxx Documentation, I get:

x86_64-w64-mingw32-g++.exe: C:/Program: No such file or directory

The path to the compiler is correct. Obviously there is some problem with
the space in C:/Program (Files). 

Any ideas where to look for the settings that caused the failure?

Hi Dieter,

Thanks for your interest in Rcpp.  We generally prefer questions about Rcpp /
RInside / ... on the rcpp-devel list.

Rcpp and its related packages expand $(R_HOME) et al to build arguments
assigned to PKG_CXXFLAGS and PKG_LIBS, either via environment variables (in
the case of the 'inline' package) or via arguments in Makevars and
Makevars.win.  We need to quote strings etc, and unfortunately it seems to
break once you have space in there --- presumably from installing R itself in
a path with spaces.  As I recall, the R-Windows FAQ recommends against it
too.  as spaces in filenames are not supported.

I know of no other fix than to move your R installation.  Or to manually
rewrite the installation / build snippets.  Things will compile and link, you
"just" need
to re-build all the Makevars.win etc scripts to use absolute paths, possibly
with 8.3 notation.

Sorry,  Dirk

I know that list, but I was not sure if Path-questions are part of
"devel".

Rtools and friends must be in spaceless paths, but the installation of R
into the String-Path is the default I do not want to change without reason.

But things work Ok with vanilla c. I had already started fiddling with
Makevars, but I stopped, thinking I had missed something obvious.

Thanks, Dirk. Hope to see you in Coventry.

All Windows files have an equivalent 8.3 name without spaces.  It may differ
on different machines
and countries.   You find them by typing dir/x in the cmd window.
In the US English, the equivalences usually are

c:\>cd c:/
c:\>dir /x Pr*
 Volume in drive C is Windows7_OS
 Volume Serial Number is 1E6B-37CE
 Directory of c:\
06/09/2011  02:35 PM    <DIR>          PROGRA~1     Program Files
07/20/2011  08:35 PM    <DIR>          PROGRA~2     Program Files (x86)
               0 File(s)              0 bytes
               2 Dir(s)  360,981,925,888 bytes free
c:\>

Now we know that 64-bit R is located (in forward slash notation as used by
R) at
c:/Progra~1/R/R-2.13.1/bin/x64/R.exe

Or by shortPathName() in R.

But that does not help if R itself is generating the name (here I 
guess .Library).  R on Windows used almost always to generate 8.3 (aka 
DOS) names, but since useRs are nowadays confused by them it 
increasingly quotes canonical names.

Spaces in names are not unique to Windows: they are also common on Mac 
OS X (which has no concept of 8.3 names).   The problem (as the rw-FAQ 
points out) is poorly written packages that fail to use quotes in 
shell command lines (including those generated from makefiles).
