Priority:  normal             |   Component:  Ipopt     
 Version:  3.5 (C++ Version)  |    Severity:  normal

 When trying to build the executable in examples/ScalableProblems, I got
 the following error message:
 {{{
 $ make

 g++ -O3 -fomit-frame-pointer -pipe -DNDEBUG -pedantic-errors -Wimplicit
 -Wparentheses -Wreturn-type -Wcast-qual -Wall -Wpointer-arith
 -Wwrite-strings -Wconversion -Wno-unknown-pragmas   -I`echo
 /c/GNU/Ipopt-3.5.4/include/coin` -c -o solve_problem.o `test -f
 'solve_problem.cpp' || echo './'`solve_problem.cpp

 solve_problem.cpp: In function 'int main(int, char**)':

 solve_problem.cpp:140: error: 'strcmp' was not declared in this scope

 make: *** [solve_problem.o] Error 1
 }}}
 ----
 The function 'strcmp' is really a member of cstring/string.h, which is
 not explicitly included in 'solve_problem.cpp'. I think that most
 compilers implicitly include cstring/string.h when cstdlib/stdlib.h is
 included, and therefore this error normally does not show up. However,
 to be on the safe side with all compilers, cstring/string.h needs to be
 explicitly included.

 To successfully compile, I simply added the following code to
 'solve_problem.cpp':
 {{{
 #ifdef HAVE_CSTRING
 # include <cstring>
 #else
 # ifdef HAVE_STRING_H
 #  include <string.h>
 # else
 #  error "don't have header file for string"
 # endif
 #endif
 }}}
