[R-pkg-devel] The correct way to put additional DLLs on windows?

[Jialin Ma]

Hi everyone,

Currently my package has a script downloading additional DLLs
into "inst/libs" and being called in "Makevars.win". In this way these
DLLs get copied to libs when installing the package and I am able to
load them with "library.dynam".

However R CMD check gives the following warning.

  * checking package subdirectories ... WARNING
  Found the following non-empty subdirectories of 'inst' also used by R:
    inst/libs
  It is recommended not to interfere with package subdirectories used by
  R.

I was wondering what would be the best practice for my case, or I am safe
to ignore this warning (suppose I am planing for a CRAN submission).

I know many packages will download static library and link them at compile
time. But I haven't see any example with additional DLL files.

Thanks.
