Can't build R-package from master since #13062

[jeremiedb]

Commit #13062 by adding the symbolic links to dmlc and nnvm seems the cause of the error in building the R-package.
Thwe code in cause in the Makefile for rpkg are:

cp -rf 3rdparty/dmlc-core/include/* R-package/inst/include/
cp -rf 3rdparty/tvm/nnvm/include/* R-package/inst/include

If removing the above lines, the build of the R-package still fails. Seems like the symbollic like isn't resolved properly by the process (not too sure about this later part).

Shouldn't a build test have captured this issue?

Hi @jeremiedb , not sure how R build so I tagged someone who knows better than me. I think we do have R build procedure and it is here:
https://github.com/apache/incubator-mxnet/blob/master/ci/docker/runtime_functions.sh#L789-L802
However, I do not see R building procedure in the CI which I think this is a problem.

@jeremiedb indeed it should have. Also I notice the current recipe for building R-package in the Makefile has a few wrong commands like this

@marcoabreu do we still have R build and tests running on the CI?

[marcoabreu]

Yeah

I'll only be able to take a look in 2 days, and hopefully get it fixed.

@anirudhacharya Pull request #14068 should fix the those commands.
