We illustrate here a simple example of package dependency. We show how CMT deals with a package dependency between the package A and B.

Let's consider a package A:

> cmt create A V1
...
> cd A/v1/src
...
> more A.h
#include <iostream>

using namespace std;

class A
{
    public:
	A() {}
	~A()  {}
	void print ();
};
> more A.cxx
#include "A.h"

void A::print ()
{
	cout<<"A"<<endl;
}

We have the following requirement file:

> cd cmt
> more requirements
package A

author Vincent Garonne <garonne@lal.in2p3.fr>

library A A.cxx

macro A_linkopts " -L$(AROOT)/$(A_tag) -lA "

The macro A_linkopts will be automaticaly inserted for the link operation. The library location is specified with $(AROOT)/$(A_tag).
