[R-pkg-devel] lfftw3 error

[Rampal Etienne]

When trying to build a package with RStudio (newest R-devel and Rtools 
installed, and all packages updated), I get the following error.

C:/Rtools/mingw_64/bin/../lib/gcc/x86_64-w64-mingw32/4.9.3/../../../../x86_64-w64-mingw32/bin/ld.exe: 
cannot find -lfftw3 collect2.exe: error: ld returned 1 exit status no 
DLL was created

I suppose lfftw3 should be included in Rtools or in the package? If not, 
how do I add this, under Windows?

Kind regards,
