[Ipopt] Where to find hs071_nlp.hpp?

[Paul van Hoven]

Hi!

I successfully compiled and installed IPOpt and until now I used the
matlab interface to do my calculation. This works really fine!

But now I need to use IPOpt in a C++ environment. To get familiar with
the C++ interface I wanted to understand the tutorial posted in the
ipopt documentation. So I started with the following piece of code:


#include "IpIpoptApplication.hpp"
#include "hs071_nlp.hpp"

using namespace Ipopt;

int main(int argv, char* argc[])
	{

	SmartPtr<TNLP> mynlp = new HS071_NLP();

	SmartPtr<IpoptApplication> app = IpoptApplicationFactory();

	return 0;
	}

And here is my Makefile

CXX        = g++
CFLAGS     =
IPOPT_HOME = /path/to/Ipopt/include/coin
THIRD_PARTY = /path/to/Ipopt/include/coin/ThirdParty

LIBS      = -lm -ldl -L/path/to/Ipopt/lib/coin -lipopt
-L/path/to/Ipopt/lib/coin/ThirdParty -lcoinblas -lcoinlapack -lcoinhsl
INCLUDE   = -I$(IPOPT_HOME) -I$(THIRD_PARTY)

TARGET = IPOptDemo

all:$(TARGET)
$(TARGET): $(TARGET).o
	$(CXX) $(LIBS) -o $(TARGET) $^
	rm *.o
	

$(TARGET).o: $(TARGET).cpp
	$(CXX) $(CFLAGS) $(INCLUDE) -c $^
	
clean:
	rm *.o $(TARGET)

The problem is that I get the following error message when trying to
compile the code above:
make
g++  -I/hpath/to/Ipopt/include/coin
-I/path/to/Ipopt/include/coin/ThirdParty -c IPOptDemo.cpp
IPOptDemo.cpp:2:25: fatal error: hs071_nlp.hpp: No such file or directory
compilation terminated.
make: *** [IPOptDemo.o] Error 1

But I can't find hs071_nlp.hpp anywhere. Can anybody tell me what I
have to do to get this running?



BTW: This code here compiles fine
//#include "hs071_nlp.hpp"

using namespace Ipopt;

int main(int argv, char* argc[])
	{
	// Create a new instance of your nlp
	//  (use a SmartPtr, not raw)
	//SmartPtr<TNLP> mynlp = new HS071_NLP();

	// Create a new instance of IpoptApplication
	//  (use a SmartPtr, not raw)
	// We are using the factory, since this allows us to compile this
	// example with an Ipopt Windows DLL
	SmartPtr<IpoptApplication> app = IpoptApplicationFactory();

	return 0;
	}
