Packaging Xtensor.R

This section may be of interest to people working on packaging Xtensor.R for Linux distributions or other general-purpose packaging systems.

The Xtensor R package depends on the xtensor-r C++ header-only library.

• When installing the CRAN package the headers of xtensor-r and its dependencies are vendored in the R package.
• However, the conda-forge package does not vendor its dependencies.

The vendoring can be prevented by passing the --novendor option to the configure script, which can be passed to the R CMD INSTALL command in the following way:

R CMD INSTALL --build --configure-args='--novendor'

xtensor.r's Issues

CRAN package installation failure

I've tried to install both the dev and CRAN versions of xtensor on a cloud based Linux machine we have that runs RStudio. It has gcc 4.9.2 so I thought all would be well, but I get this message when trying to install. Any ideas? Googling doesn't get me much besides this:

xtensor pragma use

I've noticed this note in the past. Did CRAN bless this as being alright? Not sure if there is anything you can do about it anyways since I'm guessing you need it in core xtensor, but just wanted to ask.

Version: 0.9.0-0 
Check: pragmas in C/C++ headers and code 
Result: NOTE 
    File which contains pragma(s) suppressing diagnostics:
     ‘inst/include/xtensor/xstorage.hpp’ 

Pure R unit tests and include directories

The pure R unit tests fail to locate xtensor-r include directories.

The success in the original xtensor-r comes from the fact that xtensor-r is installed in the general prefix.

new release to CRAN

Hi there,

Would it be possible to release a new version to CRAN build with the latest versions of the xtensor stack please ? (i.e. xtensor=0.24.6 and xtensor-r=0.14.2)

Thanks.
