Please help me, I can not compile c++ code with ogdf libraries

[Arman Mohseni Kabir]

I downloaded OGDF and build it in linux. 

I have demo.cpp file to test if I can compile my code, but it does not work. 

The problem seems to be that the path to dependencies of the libraries being called in the demo.cpp is not recognized. 

My demo.cpp is this code:

#include "include/ogdf/basic/Graph.h"

namespace ogdf;

 

int main()

{

 Graph G;

}

I use this command to run the code:

g++ -std=c++11 -I./home/arman/ogdf/include -pthread -lm demo.cpp -LOGDF -LCOIN -DNDEBUG

and it gives me this error:

include/ogdf/basic/Graph.h:34:29: fatal error: ogdf/basic/List.h: No such file or directory

compilation terminated.

(List.h is a library called in graph.h so it seems that recognizes graph.h but does not recognize List.h which is in the same directory)

I appreciate your help.

There are several problems with that invocation.

First, I guess the correct path for your includes is
/home/arman/ogdf/include
and not
./home/arman/ogdf/include

Second, it is -lOGDF -lCOIN, not -LOGDF -LCOIN.
However, with -L you have to specify the paths where the OGDF and
COIN object files are located (e.g., -L/home/arman/ogdf/ if you have
not used an out-of-source build).

I urge you to look at the documentation in doc/build.md

Thanks

Thank You. 

I figured it out.
