问题


I am trying to install Rcplex in R on a macbook and I'm following the instruction at this link http://jrzubizarreta.com/INSTALL.

On terminal, in the folder where the unzipped Rcplex directory is, I typed

cd /Library/Frameworks/R.framework/Versions/3.4/Resources/library 

R CMD INSTALL --configure-args="PKG_CFLAGS='-m64 -fPIC' PKG_CPPFLAGS=-
I/Applications/CPLEX_Studio_Community129/cplex/include PKG_LIBS='-
l/Applications/CPLEX_Studio_Community129/cplex/examples/x86-64_osx/static_pic 
-m64 -lm -lpthread -framework CoreFoundation -framework IOKit'" Rcplex

as by instructions. However, I get the following error:

configure: error: Could not link CPLEX library using -
L/Applications/CPLEX_Studio_Community129/cplex/examples/x86-64_osx/static_pic 
-m64 -lm -lpthread -framework CoreFoundation -framework IOKit

The error persist if I use the sudo option before R CMD INSTALL [...].

The config.log states:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by Rcplex configure 0.3.2, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure PKG_CFLAGS=-m64 -fPIC PKG_CPPFLAGS=-I/Applications/CPLEX_Studio_Community129/cplex/include PKG_LIBS=-L/Applications/CPLEX_Studio_Community129/cplex/examples/x86-64_osx/static_pic -m64 -lm -lpthread -framework CoreFoundation -framework IOKit

EXSRCJAVA     = $(EXDIR)/src/java

CFLAGS  = $(COPT)  -I$(CPLEXINCDIR)
CCFLAGS = $(CCOPT) -I$(CPLEXINCDIR) -I$(CONCERTINCDIR) 
JCFLAGS = $(JOPT)

Any idea on how to fix this issue? Thank you

It says

error: unable to open output file '/Volumes/Andrews/R working

Could it be that the blank in the file/folder name causes trouble? Try to install into a path that does not have blanks in its name. And make sure that path exists and you have write permissions for it.

Update after question was updated with new error message: Now the error is this:

error: Could not link CPLEX library using -L/Applications/CPLEX_Studio_Community129/cplex/examples/x86-64_osx/static_pic -m64 -lm -lpthread -framework CoreFoundation -framework IOKit

This is the wrong path. The CPLEX libraries are not in examples/x86-64_osx/static_pic but are either in bin/x86-64_osx (dynamic library) or in lib/x86-64_osx/static_pic (static library). I don't know which of the two libraries is required, so just put both pathes into the configuration arguments (including the absolute path to your installation, of course). I am not sure whether you also have to put -lcplex or -lcplex129 (depending on whether the static or the dynamic library is required). So if you get the same error without putting these arguments, then try with them.
