I have Rcpp installed in
C:/Documents and Settings/Damberti/R/win-library/2.12/
I’m trying to use package inline to compile a simple example (below),
I’m experiencing a compilation problem due to the space in the
installation path “C:/Documents and Settings” giving this:
Error in compileCode(f, code, language = language, verbose = verbose) :
Compilation ERROR, function(s)/method(s) not created! g++.exe:
C:/Documents: No such file or directory
g++.exe: and: No such file or directory
g++.exe: Settings/Damberti/R/win-library/2.12/Rcpp/lib/i386/libRcpp.a:
No such file or directory
The error seems to be caused by missing double quote for libRcpp.a
path on this chain:
Rcpp.system.file
RcppLdPath
RcppLdFlags
Rcpp:::inlineCxxPlugin
getPlugin('Rcpp')
$env$PKG_LIBS [1] " C:/Documents and
Settings/Damberti/R/win-library/2.12/Rcpp/lib/i386/libRcpp.a"
and finally:
Compilation argument:
C:\PROGRA~1\R\R-212~1.1/bin/i386/R CMD SHLIB file3c125a01.cpp 2>
file3c125a01.cpp.err.txt

g++.exe: Settings/Damberti/R/win-library/2.12/Rcpp/lib/i386/libRcpp.a:
No such file or directory
Any suggestion (different from installing Rcpp on a different path)?
I’m using R 2.12.2, Windows XP and latest available versions of Rcpp
and inline from CRAN.
Best regards,
Den
Example:
library(inline)
src <- '
Rcpp::NumericVector xa(a);
Rcpp::NumericVector xb(b);
int n_xa = xa.size(), n_xb = xb.size();
Rcpp::NumericVector xab(n_xa + n_xb - 1);
for (int i = 0; i < n_xa; i++)
for (int j = 0; j < n_xb; j++)
xab[i + j] += xa[i] * xb[j];
return xab;
'
fun <- cxxfunction(signature(a = "numeric", b = "numeric"),
src, plugin = "Rcpp")
