[R] inline/Rcpp: Problem with space in path under Windows

[Dirk Eddelbuettel]

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
