[SCIP] Makefile-compiling

[Benjamin Müller]

Dear Kaveh,

the problem is the structure of your project. You changed the SCIPDIR 
variable to '../' which means that your project directory should be 
directly inside the SCIP directory. If your project is in the examples 
directory you should modify it to '../../'.

Your easyscip.h file should include

	#include <vector>
	#include "objscip/objscipdefplugins.h"

So, you just need to follow these steps:

1.) cd <SCIP directory>
2.) mkdir <project name>; mkdir <project name>/src
3.) copy diet.cpp and easyscip.h to <project name>/src
4.) make sure that SCIPDIR is equal to '../' and MAINOBJ = diet.o

Regards,
Benjamin

But unfortunately, I could not compile a sample problem using SCIP to understand how to apply SCIP for my model. I found the attached example on the internet which is very useful for me but I am in trouble compiling it because a simple makefile that I wrote cannot find the libraries and header files of SCIP. In fact, I found out every header file such as objscip.h includes several other headerfiles inside which make it complicated to a simple Makefile to find and call them. I also tried to modify the corresponding Makefile for vrp problem which is provided in the example folder but I failed. I would appreciate if you let me know how I can use SCIP to solve my model. Is there any specific makefile to compile and run similar models to mine in C++ ?
