NLopt

This relates to pre-installation of NLopt though should be applicable to R/nloptr itself.

We download the latest NLopt according to https://nlopt.readthedocs.io/en/latest/, notably

wget -qO- https://github.com/stevengj/nlopt/archive/v2.7.1.tar.gz | \
tar xvfz -
cd nlopt-2.7.1/
cmake -DCMAKE_INSTALL_PREFIX=${HPC_WORK} .
make
make install

Additional options are available from its homepage.

R/nloptr

Within R, we have seen error messages from install.packages("nloptr"),

test-C-API.cpp:108:35: error: call of overloaded 'abs(__gnu_cxx::__alloc_traits<std::allocator<double> >::value_type)' is ambiguous
     expect_true(abs(res[1] - 8./27) < 1.0e-4);

so we manually proceed with

Rscript -e 'download.packages("nloptr",".")'
tar xfz nloptr_2.0.0.tar.gz
cd nloptr
confiugre

We then do several things,

• rename configure to be configure.save.
• modify src/Makevars to point to -L${HPC_WORK}/lib64 to enable -lnlopt, so it becomes

  CXX_STD = CXX11
  PKG_CPPFLAGS = -I../inst/include -I/rds/user/jhz22/hpc-work/include
  PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) -L/rds/user/jhz22/hpc-work/lib64 -lnlopt
  

• change src/test-C-API.cpp such that abs() there turns into fabs().

We now can furnish the installation with

R CMD INSTALL nloptr

R/nloptr 2.0.4

It proceeds smoothly as follows,

module load ceuadmin/NLopt/2.7.1
Rscript -e 'remotes::install_github("astamm/nloptr")'
