Unable to install httpuv - R 3.5.3

[ms609]

A different underlying issue, I think, to #353
Occurs also under R3.5.0 (which is where I'd really like to install).

Hi @ms609, I think you're running into an issue caused by changes in CRAN policy around packages that contain C++ code. If you're interested in the backstory, there's an article on the tidyverse blog that explains the change.

The fix as described there is that for R <= 3.5, you may need to make a small change in your ~/.R/Makevars file to add the following line:

CXX_STD=CXX11

Please try this and let us know how it goes.

Thanks for the suggestion; this sounds like a likely explanation. As I have multiple versions of R installed, I'll have to have a proper stab at setting up the Makevars for 3.5, which I've not got round to yet – but I'll let you know how I get on.
