Can anyone please help me here?
the IpoptApplication.cpp and .hpp do exist, plus i have specified the ipopt.lib file path in the linker setting of the property page.
what is confusing is that, when lapack, asl, hsl and ipopt are compiled, each produces its own 'ipopt.lib' of a different size, and i am setting the lib path to the ipopt.lib of ipopt version, maybe that makes a difference? where are the lapack, asl hsl versions used? why r they created?
In brief this is a requirement for a scientific optimization library that links to visual c++ 2005 , (C++ code) and that can run on windows XP.
I tried to install Ip opt (interior point opt) but am getting linking
errors (LNK2019 error) even though the specified lib file is in the
linker path. Need advice on running any scientific optimizer that can interface to my C++ code. The main requirement is for an optimizer to perform cross correlation of histograms to perform image matching. Is there any other optimization library that can do this?
