I am facing the following error:

someone out ther:Pls help me out.
Thanks in advance.

If you want to get rid of this error, simply comment out this line:
//std::ostream& _stream;
And you file looks like in have two copies of some other file pasted one after another - class declaration suddenly terminates and copyright header begins.

typedef std::list<Source> ErrorList;

priethe,
In the future, please use code tags, so that we can talk about your code and reference specific line numbers.
I must admit, newb16 is right about your code looking a little confused.
What I see is that you are declaring a nested class TextOutput within the class TextOutput.
Is that what you really intended?
Or do you want to have a class ::Test::TextOutput in addition to a top level class ::TextOutput ?
Why don't you try to sort that out, and then re-post your corrected code with any other difficulties you may be having?
Luck!
oh! am sorry.I had pasted the code twice.
pls look into this :
This is a header file which I am including in my source file test.cpp.
cpptest-textoutput.h
-----------------------
/** \file */
#ifndef CPPTEST_TEXTOUTPUT_H
#define CPPTEST_TEXTOUTPUT_H
#include <iostream>
#include <list>
#include "cpptest-source.h"
#include "cpptest-output.h"
namespace Test
{
/// \brief Text output handler that outputs to the a stream.
///
/// %Test suite output handler that writes its information as text to a
/// a stream. It it possible to select between two different operational
/// modes that controls the detail level, see Mode.
///
class TextOutput : public Output
{
public:
/// Output mode.
///
enum Mode
{
/// Terse output mode, which only shows the number of correct tests.
///

/// Verbose output mode, which also shows extended assert
/// information for each test that failed.

Verbose
};
TextOutput(Mode mode, std::ostream& stream = std::cout)
{
}
virtual void finished(int tests, const Time& time);
virtual void suite_start(int tests, const std::string& name);
virtual void suite_end(int tests, const std::string& name,
const Time& time);
virtual void test_end(const std::string& name, bool ok,
const Time& time);
virtual void assertment(const Source& s);
private:
typedef std::list<Source> ErrorList;
Mode _mode;
// std::ostream& _stream;
ErrorList _suite_error_list;
std::string _suite_name;
int _suite_errors;
int _suite_tests;
int _suite_total_tests;
int _total_errors;
};
} // namespace Test
#endif // #ifndef CPPTEST_TEXTOUTPUT_H
source file - test.cpp
-------------------------
#include <iostream.h>
#include "cpptest.h"
#include "cpptest-suite.h"
#include "cpptest-output.h"
#include "cpptest-textoutput.h"
using namespace std;
class mytest_test : public Test::Suite
{
public:
mytest_test()
{
TEST_ADD(mytest_test::first_test);
TEST_ADD(mytest_test::sec_test);
}
private:
void first_test();
void sec_test();
};
void mytest_test::first_test()
{
cout<<" in first test \n";
}
void mytest_test::sec_test()
{
cout<<" in sec test \n";
}
int main()
{
mytest_test mtt;
Test::TextOutput output(Test::TextOutput::Verbose);
return mtt.run(output) ? EXIT_SUCCESS : EXIT_FAILURE;
}
also I tried the solution given by newb16.It gives the following errors.
/tmp/cceUiSFX.o: In function `Test::TextOutput::TextOutput(Test::TextOutput::Mo de, std::basic_ostream<char, std::char_traits<char> >&)':
test.cpp:(.text._ZN4Test10TextOutputC1ENS0_4ModeER So[Test::TextOutput::TextOutput(Test::TextOutput::Mod e, std::basic_ostream<char, std::char_traits<char> >&)]+0x1e): undefined reference to `vtable for Test::TextOutput'
/tmp/cceUiSFX.o: In function `Test::TextOutput::~TextOutput()':
test.cpp:(.text._ZN4Test10TextOutputD1Ev[Test::TextOutput::~TextOutput()]+0xe): undefined reference to `vtable for Test::TextOutput'
collect2: ld returned 1 exit status
Do you compile and link it with cpptest-textoutput.cpp ?
i just compile test.cpp file.already cpptest-textoutput is included as a header file
vtable for Test::TextOutput may happen if you don't implement virtual methods you declare.
Here's a little bit on tags, that'll help folks read your code.
Please use them. It really does help.
Anyway, with that last set of errors you posted, it looks like you're not linking your driver with cpptest-textoutput.o
Perhaps you need to compile with something like: - g++ test.cpp cpptest-textoutput.cpp -o myExecutable
Luck!
