在Winbuild上编译R包时编译C ++错误

Question

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' ...
** libs

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.

Answer 1

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.
