[R-pkg-devel] third part software dependency

[Serguei Sokol]

Hi,

I am preparing a new package r2sundials for submission to cran. It 
depends on third part software 
(https://computing.llnl.gov/projects/sundials). This will be my first 
submission of the kind so I am wondering how it is supposed to be tested 
so that I can reliably check the box "tested on R-devel" during 
submission process?
I suppose that sundials is not installed on windev. And even if it was, 
I need a particular option in this software (index size set to 32 bits) 
which is probably not activated in the hypothetical installation. So I 
cannot use win-builder.r-project.org.
Am I supposed to install current r-devel version and test my package on 
it locally?

And another question.
Recently, I had to fix many LTO (link time optimization) related issues 
in a third part software included in one of my old packages. Have I to 
test with LTO activated the new package too given that it is _not_ 
included in the package ?

Thanks to share your experience and wisdom.

Best,
Serguei.
