#271: issue with IpRandon01

Priority:  normal    |  Component:  Ipopt
 Version:  3.12      |   Severity:  normal

---------------------+------------------------
 There is an issue with compiling version 3.12.4 on Ubuntu 14.04.
 {{{HAVE_STD__RAND}}} is not set properly.  In {{{IpUtils.cpp}}} I find the
 comment

 {{{
 #  else
     /* this is a workaround for gcc 4.8.3, for which the test for rand()
 that our old configure sets up does not work */
 #   if defined(__GNUC__) && __GNUC__ == 4 && __GNUC_MINOR__ == 8 &&
 __GNUC_PATCHLEVEL__ >= 2
       return Number(rand())/Number(RAND_MAX);
 }}}

 but it doesn't seem to help

 This is my compiler version:

 {{{
 g++ --version
 g++ (Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4
 }}}

 As a workaround I added {{{-DHAVE_STD__RAND}}} to {{{ADD_CXXFLAGS}}}
