# Then you could install the package: nloptr in the R environment

In the R environment

install.packages('nloptr')

Issues

I am not sure if everyone will get this kind of issue

Error: package or namespace load failed for ‘nloptr’ in dyn.load(file, DLLpath = DLLpath, ...):

Even though, the pkg-config has confirmed we have had installed nlopt package.

Fix

Then I create a soft-links of the libnlop in the $HOME/lib directory.

cd $HOME/lib
ln -s $HOME/softwares/nlopt/lib/lib* ./
export LD_LIBRARY_PATH=$HOME/lib/:${LD_LIBRARY_PATH}

Finally, we could install the R package in the R.

install.packages('nloptr')

TL;DR

The package installation is similar as the previous hdf5r installation. There’re some differences in the install processes:

  1. The installation was based on cmake rather than make only.

  2. As the nloptr (with r in the name) package installation was based on the pkg-config to find the dependency libraries, we can’t put the libraries (xxx.so files) in the $HOME/lib directory and then the nloptr knows where they are. We need to to tell pkg-config where I put the libraries.
