Hi r-package-devel
I am working on updating my package `sundialr` (
https://cran.r-project.org/web/packages/sundialr/index.html), wherein I was
earlier bundling the C source files with the package, but now I am using
`cmake` to create static libraries for the upstream C library SUNDIALS
which the package provides an interface for. In brief, the previous
approach can be found at:
https://github.com/sn248/sundialr/blob/master/src/Makevars
And the new approach can be seen below (heavily borrowed from nloptr
package installation approach):
https://github.com/sn248/sundialr/blob/cmake-install/tools/cmake_call.sh
The second approach works successfully on linux and macOS platforms
(checked by rhub).
I am struggling to get this working on a Windows platform, and have looked
at a few packages (e.g., nloptr, rcppredis, openssl) which have solved this
issue. As I understand the following steps are required to get the static
libraries in correct locations for package installation on the Windows
Technically, it is possible to build sundials from the downloaded source
code using cmake on Windows pretty much like on Unix. Rtools includes
cmake as well as the toolchains and libraries to build sundials. The
older version of sundialr was building sundials on Windows using make,
there is no technical reason why it couldn't do that using cmake (and
downloaded _sources_) as well.
I was able to build the new sundialr on my Windows with these changes,
and the package passed its checks (with some warnings):
1. delete Makevars.win and Makevars.ucrt
2. create configure.win file with this content in the package root directory

#! /bin/sh
./configure $*

Whenever in doubt, I would recommend starting with the same code for
Unix and Windows. Only customize for Windows (or macOS or another
system) if needed.

1) Host the .tar.gz files or .zip files on https://github.com/rwinlib/
(deprecated now) or https://github.com/r-windows/bundles/releases/download/
which should contain the static libraries (*.a files) in separate folders
for i386, x64-ucrt and x-64 platforms and required header files in the
`include` folder.
2) Use a winlibs.R file within the `tools` sub-directory in the package
file structure to download the .zip or .tar.gz file and extract them to a
`windows` directory.
3) Set PKG_CPPFLAGS and PKG_LIBS via Makewars.win file in src sub-directory
in the package files.
Currently, I am struggling with Step #1, i.e., how to create the required
.zip or .tar.gz files and host them on
https://github.com/r-windows/bundles/releases for download. I will be
thankful if any one can provide some guidance in this regard.
Sincerely
Satya
