[Ipopt] Linking problems in MinGW

[Stefan Vigerske]

Hi,

sounds like you are missing the gfortran libraries on your linkline, 
e.g., -lgfortran.
Ipopts build includes a file share/coin/doc/Ipopt/ipopt_addlibs_cpp.txt 
which lists all the flags necessary for linking with Ipopt. That may be 
handy...
