[Ipopt] Problem Compiling under MSys/MinGW

[Krish Krishnan]

Hi Stefan:

I commented out the offending code, and the compilation went through. Thanks a lot.

Hi,

looks for me like your gcc is using the boost library as a stl 
implementation. The boost might implement the constructor of std::list 
differently then the normally used implementation.

The troublemaker seem to be the line
     std::list<TripletEntry> entry_list(nonzeros);
at IpTripletToCSRConverter.cpp:63, where nonzeros is an int.
I presume that normally the TripletEntry() constructor is used to create 
the (empty) elements of the list. But in your case, the list constructor 
tries to use the TripletEntry::operator=(TripletEntry&) function which 
is explicitly made private.

What happens when you comment out line 105 of 
src/Algorithm/LinearSolvers/IpTripletToCSRConverter.hpp ?

I doubt that it has something to do with the way MUMPS is provided to Ipopt.

Best,
Stefan

PS: If that does not work for you, Andreas would like to see you opening 
a ticket :-).
