[Ipopt] Problem Compiling under MSys/MinGW

[Krish Krishnan]

Hi All:

I am trying to compile IpOpt-3.4.0 in Windows under MSys/MinGW.  I have gcc 4.3.0.  The ./configure --enable-dos-compile goes through without any problem.  When I invoke make, compilation halts with the following error message:

c:\program files\mingw\bin\../lib/gcc/mingw32/4.3.0/include/c++/bits/stl_list.h:420:   instantiated from 'std::list<Ipopt::TripletToCSRConverter::TripletEntry, std::allocator<Ipopt::TripletToCSRConverter::TripletEntry> >'
IpTripletToCSRConverter.cpp:63:   instantiated from here
IpTripletToCSRConverter.hpp:105: error: 'void Ipopt::TripletToCSRConverter::TripletEntry::operator=(const Ipopt::TripletToCSRConverter::TripletEntry&)' is private
c:\program files\mingw\bin\../lib/gcc/mingw32/4.3.0/include/c++/bits/boost_concept_check.h:209: error: within this context
IpTripletToCSRConverter.hpp: In member function 'void __gnu_cxx::_SGIAssignableConcept<_Tp>::__const_constraints(const _Tp&) [with _Tp = Ipopt::TripletToCSRConverter::TripletEntry]':

c:\program files\mingw\bin\../lib/gcc/mingw32/4.3.0/include/c++/bits/stl_list.h:420:   instantiated from 'std::list<Ipopt::TripletToCSRConverter::TripletEntry, std::allocator<Ipopt::TripletToCSRConverter::TripletEntry> >'
IpTripletToCSRConverter.cpp:63:   instantiated from here
IpTripletToCSRConverter.hpp:105: error: 'void Ipopt::TripletToCSRConverter::TripletEntry::operator=(const Ipopt::TripletToCSRConverter::TripletEntry&)' is private


Apparently a private function is being called directly.  Can someone please help me here?

Thank you.

Krish
