[Cppunit-devel] getting started with cppunit

[Richard U. <ric...@im...>]

Hi,
I am new with cppunit, but when I try out the very
first example from the cookbook, the linker exits with errors.

I think, the package is well installed on my linux machine
within: /usr/local/stow/cppunit-1.8.0
I added /usr/local/stow/cppunit-1.8.0/include to PATH
I copied libcppunit.a to my working dir: ~cppunit

I created the file complex.cpp, tried to compile with:
g++  libcppunit.a complex.cpp
and got the errors at the end of the message
can you help me or give me a working example?
thanks Richard

complex.cpp:
===========
#include <sstream>
using namespace std;
#include "cppunit/TestCase.h"
using namespace CppUnit;
class Complex {
  friend bool operator==(const Complex &a, const Complex &b);
  double real, imaginary;
  public:
    Complex(double r, double i=0)
      :real(r), imaginary(i)
    {}
};
bool operator==( const Complex &a, const Complex &b ){
    bool b0=false;
    b0 = (a.real== b.real) && (a.imaginary == b.imaginary);
    return b0;
    //return eq(a.real, b.real) && eq(a.imaginary, b.imaginary);
}
class ComplexNumberTest : public CppUnit::TestCase{
public:
  ComplexNumberTest( std::string name ) : CppUnit::TestCase( name ) {}
  ComplexNumberTest(  ) : CppUnit::TestCase(  ) {}

  void runTest(){
    CPPUNIT_ASSERT( Complex(10,1) == Complex (10,1) );
    CPPUNIT_ASSERT( !(Complex(1,1) == Complex (2,2)) );
  }
};

int
main(int argc, char** argv)
{
  //string myname;
  ComplexNumberTest *mytest;
  mytest = new ComplexNumberTest();
  return 0;
}
