[Rcpp-devel] linking fail when building examples of my local copy of Rcpp gallery (windows)

Hi Robin,

Those exact linker errors occur if you use a different version of MinGW than the Rcpp static library. Could that possibly be the case?

If so make sure to install Rcpp from source. For example:

install.packages("C:/CRAN/Rcpp_0.10.3.tar.gz", repos=NULL, type="source")

Make sure you have the Rtools bin directory and the MinGW version you are using in your path.

You said you don't have C++11; are you using a version of GCC older than that supplied with Rtools? In that case you may have issues compiling for R 64-bit in my experience. Run this from R i386:

install.packages("C:/CRAN/Rcpp_0.10.3.tar.gz", repos=NULL, type="source", INSTALL_opts=c("--no-multiarch"))

Best of luck,

Salut list,
I'm trying to become soon a (small) contributor to Rcpp Gallery and I would like to be able to visualize the result before pushing it. I'm on windows... 

I managed to install jeckyll and made it work (this http://bradleygrainger.com/2011/09/07/how-to-use-github-pages-on-windows.html helped me if other people want to do the same).
I removed all src that are  c++11 since I don't have it (that would be another question about having it on windows but I did not try yet) 

I did "make" in the src folder
but it appeared that I had to change the first two line, my dumb guess was that it did not like the relative path stuff, I changed the first two line of the makefile to KNIT = /c/GitHub/rcpp-gallery/_scripts/knit.sh
POSTS_DIR = /c/GitHub/rcpp-gallery/_posts

then I did "make" again and got a lot of ...

Erreur dans function (file = "", code = NULL, env = globalenv(), rebuild = FALSE,  :
  Error occurred building shared library.
Calls: knit ... block_exec -> in_dir -> <Anonymous> -> do.call -> <Anonymous>

I know this has to do with my library path (and actually when I launch the function "knit(input,output)" in R for a given Rcpp example this works and generate the markdown file) but don't find where this comes from.

any idea of what I'm doing wrong ?
