 I'm facing difficulty in installing ipopt as a R Package. I get the
 following error:

 For some reason, the IpJournalist.cpp can't find stdio.h and string.h
 headers. Any clues why this may be so and how this could be fixed?

Comment (by stefan):

 Probably because the defines that specify whether stdio.h or string are
 available are not defined here. They are defined during the build of
 Ipopt, but not when building something that depends on Ipopt.

 Main problem is that your build of the R-interface seems to try to build
 some Ipopt source file. I don't know why this is, because according to
 https://projects.coin-
 or.org/Ipopt/browser/stable/3.12/Ipopt/contrib/RInterface/src/Makevars.in#L34
 only three files should be build:
 {{{
 OBJECTS = ipoptr.o IpoptRNLP.o IpoptRJournal.o
 }}}
