[Gate-users] unable to compile Gate on OS X Lion: problems with std::ostringstream os(str, 100)

[Mojca Miklavec]

Hello,

ever since upgrade I'm fighting with installation of Gate.

There are many errors, among them for example:

Entering source/arf ...
Compiling GateARFTableMgr.cc ...
In file included from src/GateARFTableMgr.cc:13:

Google returns me hints that this code might be invalid, only not
shown as such when compiled with gcc. See:
    http://llvm.org/bugs/show_bug.cgi?id=9627
    http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49470
Greping Geant4 sources doesn't reveal any single occurence of the same
construct.

Can somebody please help me out? How should I fix the code:

  char st[100];
  //LF
  //std::ostrstream os(st,100);
  std::ostringstream os(st,100);
  //LF
  for (G4int i=0; i<vec.size(); i++) os << vec[i] << " ";

to make it compile?

Thank you,
    Mojca
