[ubuntu-mono] [Bug 1067545] Re: Ice C++ Applications not building under (K)Ubuntu 12.10

[HP]

This bug will prevent building the new gnuradio-3.7 release on Ubuntu
12.10 (the same problem with upCast), so a *lot* of people will be
affected. Please fix it if possible.

Title:
  Ice C++ Applications not building under (K)Ubuntu 12.10

Status in “zeroc-ice” package in Ubuntu:
  Confirmed

Bug description:
  Ice 3.4.2 seems to have problems with gcc 4.7. cpp files created via slice2cpp can not be built using gcc 4.7
  I've tried it with my own Ice application and also the "Hello" Demo including in the Ice 3.4.2 Demos: http://www.zeroc.com/download.html#demo

  Compilation of automatically created cpp files fails with errors like
  this: /usr/include/Ice/Handle.h:66:13: error: ‘upCast’ was not
  declared in this scope, and no declarations were found by argument-
  dependent lookup at the point of instantiation [-fpermissive]

  A patch for Ice 3.4.2 & gcc 4.7 is available here:

  gcc4-7-a.html
