takes a minute: Sign up Error in sourceCpp after installing Rtools up vote 2 down vote favorite A month ago I installed Rtools all by default options on my personal computer and was able to write C++ functions in R ever since. Now I am trying to install Rtools on my company's computer and unable to correctly install Rtools. I rstudio believe it has something to do with the PATH or some relevant thing that I don't quite understand. Help is so needed. Below are my steps and results: Install R-3.03 in the local drive c; successful install.packages(c("Rcpp","installr")); successful library(installr) install.Rtools(). In this step there's one thing suspicious: I only chose "Save version information to registry". 5. library(Rcpp); evalCpp("1 + 1"); and I got the following: running command: make -f "C:/R- 30~1.3/etc/i386/Makeconf" -f "C:/R-30~1.3/share/make/winshlib.mk" SHLIB_LDFLAGS='$(SHLIB_CXXLDFLAGS)' SHLIB_LD='$(SHLIB_CXXLD) Warning message: SHLIB="sourceCpp_35432.dll" OBJECTS="file1bb831d14d68.o"' had status 127 Error in sourceCpp(code = code, env = env, rebuild = rebuild, showOutput = showOutput, : Error 1 occurred building shared library.

You've installed rcpp into a directory with spaces in the path and this is where the problem is: http://stackoverflow.com/questions/12702251/rinside-installation-e
