link error problem
Dear linuxers,

I'm a novice in C++ programming.
I wrote a ReadFile class in file ReadFile.cpp.
After that, I wrote a test.cpp, which contains a main function, to test whether my class work well.
I follow the following steps to compile the ReadFile.cpp file.
g++296 -c ReadFile.cpp -o ReadFile.o
g++296 ReadFile.o test.cpp -o test.o
I got two link error.
One mention that one of my funtions which called atoi contained in ReadFile.o was duplicated declared in file/tmp/xxxxxx.o(xxxxxx varies each time I link the program).
The other says one of the pointer in main function ReadFile *read_file_ = new ReadFile() was undefined reference to ReadFile's virtual table.

Would someone be kind enough to tell me how can I solve the problem?

Thanks in advance.

Sincerely,
Kun
