My package (slfm) uses Rcpp to connect C++ code to R. Its check runs OK on linux, but I get this error when trying to compile it using WinBuild:
* installing *source* package 'slfm' ...

Has anyone experienced it before? Is it related to configuring Rcpp? Strange thing is: I haven't changed anything on Rcpp configuration, just some simple lines on C++ code and it was running OK before. Version 0.1 in CRAN is stable.
You are not linking with the LAPACK and BLAS libraries which are used by the code.
Easiest fix: look at the Makefile.win created by the package skeleton generator.
