I am trying to install the R package nloptr on a CentOS Linux machine that doesn't have internet connection as follows:
install.packages("/home/ravi/nloptr_1.0.4.tar.gz", repos = NULL, type="source")
This command in turn looks for the following file online
http://ab-initio.mit.edu/nlopt/nlopt-2.4.2.tar.gz
However, this fails since there is no internet connection to the machine.
I tried the suggestion from the following stackoverflow post:
trouble with Installing nloptr by locally on Ubuntu
I changed the URL in configure and configure.ac files as follows:
NLOPT_URL="file:///home//ravi//${NLOPT_TGZ}"
However, I get the following error when I try to install the package again:
> install.packages("/home/ravi/nloptr_1.0.4.tar.gz", repos = NULL, type="source")
* installing *source* package 'nloptr' ...
files 'configure', 'configure.ac' have the wrong MD5 checksums
ERROR: 'configure' exists but is not executable -- see the 'R Installation and Administration Manual'
* removing '/opt/vertica/R/library/nloptr'
Warning message:
In install.packages("/home/ravi/nloptr_1.0.4.tar.gz", :
installation of package '/home/ravi/nloptr_1.0.4.tar.gz' had non-zero exit status
Can someone guide me on how to install this R package locally?
Update 1
Based on the suggestion from Dirk on installing nlopt first, I followed the instructions given in the following page:
http://ab-initio.mit.edu/wiki/index.php/NLopt_Installation
I installed nlopt as follows :
./configure --enable-shared
make
make install
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib
When I tried to re-install nloptr in R, it doesn't look for the nlopt link anymore but throws the following error:
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object '/opt/vertica/R/library/nloptr/libs/nloptr.so':

Error: loading failed

Update 2
As suggested by Dirk, I looked into the ldconfig command and used the following reference:
http://codeyarns.com/2014/01/14/how-to-add-library-directory-to-ldconfig-cache/
I edited the /etc/ld.so.conf file, added the directory /usr/local/lib which contains the shared library and ran the ldconfig command. This added the relevant shared library as shown below:
libnlopt.so.0 (libc6,x86-64) => /usr/local/lib/libnlopt.so.0
libnlopt.so (libc6,x86-64) => /usr/local/lib/libnlopt.so
However, when I tried reinstalling the nloptr package, I still get the same shared object error.
Could someone guide me on the shared library error?
Answer
When you say [t]his command in turn looks for the following file online you only get half the story. Together with Jelmer, the maintainer of the actual nloptr package, I modified the package to do the following:
- look for an install libnlopt library, and, if found, use it
- if not found fall back to the old behaviour and download the library
So you could simply install nlopt via
sudo apt-get install libnlopt-dev
(or the equivalent sudo dpkg -i /media/.... pointing to the file from a
USB drive etc pp) and then reinstall the nloptr package. It will just work. On my machine:

Note how it compiled only two files from the actual R packages having found the nlopt installation.
