Help with getline(...) call in C++ program

Hi,

I'm trying to compile a C++ program on my Powerbook G4 running the latest Mac OS X. I can compile the code on another linux system (Ubuntu) but I can't compile on the Mac. It says:

config_reader.cpp: In function 'int read_config(char*, int ( )(char, char*), int)':
config_reader.cpp:78: error: 'getline' was not declared in this scope
make: * [config_reader.o] Error 1

I am not sure what to make of this, since the program compiles flawlessly on Ubunutu.

Is there some extra library that I have to add?

Any help would be greatly appreciated, I really want to use my Mac to develop this application!

PowerBook G4, Mac OS X (10.4.7), 1.5 GB ram

Thanks for the suggestions. I looked around and found out what my problem was.

First off it was a C program, not a C++ program. It was being compiled using g++ which threw me off for a bit of time.

So the getline() function is NOT part of standard C, it is a non-standard method available in GNU C. You can check to see if you have the getline() function be looking at your stdio.h file.

The Apple implementation of C does not include the getline function. As a workaround you can download the Xfree86 implementation of getline from:
http://cvsweb.xfree86.org/cvsweb/cvs/lib/getline.c

This thread helped me out quite a bit:
