Compiling a C++ program with gcc
gcc can actually compile c++ code just fine. The errors you received are linker errors, not compiler errors. Odds are that if you change the compilation line to be this: which makes it link to the standard c++ library, then it will work just fine. However, you should just make your life easier and use g++.

EncodeAndSend is not a static function, which means it can be called on an instance of the class CPMSifDlg. You cannot write this: It should rather be called as:
Static array vs. dynamic array in C++
Local arrays are created on the stack, and have automatic storage duration — you don’t need to manually manage memory, but they get destroyed when the function they’re in ends. They necessarily have a fixed size: Arrays created with operator new[] have dynamic storage duration and are stored on the heap (technically the “free store”). They can … Read more
Division in C++
In the expression 1 / 6, both numbers are integers. This means that this division will perform integer division, which results in 0. To do a double division, one number has to be a double: 1.0 / 6 for example.
std::out_of_range error?
I’m dealing with a file with a linked list of lines with each node looking like this: and I’m writing a function that adds spaces at the beginning of the lines found in the variable text, by calling functions like linelist_ptr->text.insert(0,1,’\t’); The program compiles, but when I run it I get this error: Any ideas?
What is the difference between std::atoi() and std::stoi?
1). Are there any other differences between the two? I find std::atoi() a horrible function: It returns zero on error. If you consider zero as a valid input, then you cannot tell whether there was an error during the conversion or the input was zero. That’s just bad. See for example How do I tell if the c … Read more
Getting error “a nonstatic member reference must be relative to a specific object” while both member are in the same class
In C++ you can not access a non static class member from a static method. Make it a normal method and try like below:- Else declare pub as static member Also refer to the below answer C++ static member functions and variables
