21[PAGE]hello_lemon[PAGE] Compile Your First Code
22
23First of all you have to install LEMON on your system (see
24<a href="http://lemon.cs.elte.hu/trac/lemon/wiki/InstallGuide"><b>our
25web page</b></a> for instructions).
26After that you can paste the following code segment into a file
27<tt>hello_lemon.cc</tt> to have a first working program that uses LEMON.
28
29\dontinclude hello_lemon.cc
30\skip #include
31\until }
32
33In this small example a directed graph is created with two nodes and
34an arc added to it.
35
36Now let us compile this code.
37(We suppose that you have it in a file called <tt>hello_lemon.cc</tt>.)
38
39If LEMON is installed <b>system-wide</b> (into directory \c /usr/local),
40then it is very easy to compile this program with the
41following command (the argument <tt>-lemon</tt> tells the compiler
42that we are using the installed LEMON).
43
44\verbatim
45g++ -lemon -o hello_lemon hello_lemon.cc
46\endverbatim
47
48As a result you will get the exacutable \c hello_lemon in the current
49directory, which you can run by the following command.
50
51\verbatim
52./hello_lemon
53\endverbatim
54
55If LEMON is installed <b>user-local</b> into a directory
56(e.g. <tt>~/lemon</tt>), then compiling the code is a bit more difficult.
57You have to issue a command like this.
58
59\verbatim
60g++ -lemon -I ~/lemon/include -L ~/lemon/lib -o hello_lemon hello_lemon.cc
61\endverbatim
62
63If everything has gone well, then our program prints out the followings.
64
65\verbatim
66Hello World! This is LEMON library here.
67We have a directed graph with 2 nodes and 1 arc.
68\endverbatim
69
70If you managed to compile and run this example code without any problems,
71you may go on reading this tutorial to get to know the basic notions,
72features and tools of LEMON. However if you encountered problems that
73you did not manage to solve, do not hesitate to
