   Hello,
   And thanks for helping out.
   I have the files
   
       ~$ ls mxnet/lib/libmxnet.so 
       -rwxr-xr-x 1 lorenzo lorenzo 71740832 Jul 24 17:25 mxnet/lib/libmxnet.so
   
       ~$ ls mxnet/R-package/inst/libs/libmxnet.so 
       -rwxr-xr-x 1 root root 71740832 Jul 24 21:57 
mxnet/R-package/inst/libs/libmxnet.so
   
   What I do not have is 
       /home/lorenzo/mxnet/R-package/R-package/inst/libs/libmxnet.so
   
   because I do not have an R-package directory nested inside another R-package 
directory.
   This is the content of my R-package
   
   ls R-package/
   total 40
   drwxr-xr-x 2 lorenzo lorenzo   213 Jul 24 17:11 demo
   -rw-r--r-- 1 lorenzo lorenzo  1036 Jul 24 17:11 DESCRIPTION
   -rw-r--r-- 1 lorenzo lorenzo   507 Jul 24 17:11 dummy.NAMESPACE
   drwxr-xr-x 4 root    root       45 Jul 24 18:06 inst
   -rw-r--r-- 1 lorenzo lorenzo 11350 Jul 24 17:11 LICENSE
   -rw-r--r-- 1 root    root      520 Jul 25 22:45 NAMESPACE
   drwxr-xr-x 2 lorenzo lorenzo  4096 Jul 24 17:11 R
   -rw-r--r-- 1 lorenzo lorenzo  1170 Jul 24 17:11 README.md
   drwxr-xr-x 2 lorenzo lorenzo  4096 Jul 24 18:07 src
   drwxr-xr-x 3 lorenzo lorenzo    30 Jul 24 17:11 tests
   drwxr-xr-x 2 lorenzo lorenzo  4096 Jul 24 17:11 vignettes
   
   And I did not alter anything by hand in the structure of the directory. All 
I did was
   
   git clone --recursive https://github.com/apache/incubator-mxnet.git mxnet
   cd mxnet/docs/install
   ./install_mxnet_ubuntu_python.sh
   ./install_mxnet_ubuntu_r.sh
   
   Could it be a trivial problem, meaning that everything is fine but for some 
reason R gets confused and looks for the library in the wrong place?

   As to building from source according to
   $ git clone --recursive https://github.com/apache/incubator-mxnet
   $ cd incubator-mxnet
   $ echo "USE_OPENCV = 1" >> ./config.mk
   $ echo "USE_BLAS = openblas" >> ./config.mk
   $ make -j $(nproc)
   
   I have a problem: the process fails due to the absence of cuda.h, but I 
would like to build for the CPU only.
   Any suggestion is very welcome!
