Question

I am new to c++ and was working with OOP concepts.

I created a header file(account.h), a method definition file(account.cpp) and a main file(ex2.cpp).

When, I am compiling the main file, I am getting an error as "undefined reference to".

The detailed error is:-/tmp/ccps76QE.o: In function `main':
ex2.cpp:(.text+0x8d): undefined reference to `Account::init(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned long, double)'
ex2.cpp:(.text+0xb7): undefined reference to `Account::display()'
ex2.cpp:(.text+0xd6): undefined reference to `Account::display()'
ex2.cpp:(.text+0x134): undefined reference to `Account::init(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned long, double)'
ex2.cpp:(.text+0x15e): undefined reference to `Account::display()'
ex2.cpp:(.text+0x178): undefined reference to `Account::display()'

.

Kindly help me regarding this issue as I am new to programming and c++

You have to compile ex2.cpp and account.cpp and link, currently you are only compiling ex2.cpp — M.M, Nov 09 '19 at 21:15
Thanks a lot for your reply. Can you please guide me how to that? — Raj Rajeshwari Prasad, Nov 09 '19 at 21:41
@RajRajeshwariPrasad E.g. `g++ account.cpp ex2.cpp` Just list all the `.cpp` on the compiler invocation. — walnut, Nov 09 '19 at 21:49
