Network / Packet on Mac OS

« on: July 26, 2013, 04:02:58 pm »

Hello, I really need help!  I'm not really good in programming.
I've been searching for one week! But I really couldn't find any answer.

I followed a tutorial that I found on internet and it works very well on my PC.

I tried to do the exact same thing on my Mac .... and 

I'm not gonna show you all my code!
the problem is when I try to insert/extract a STRING from a packet!

std::string text;
packet >> text;

When I try with a "int" or "char" it works perfectly!
On my PC, the string works, so the problem is not from code I guess...

Here's my wonderful error

ld: warning: directory not found for option '-L/usr/local/lib'
Undefined symbols for architecture x86_64:
  "sf::Packet::operator>>(std::string&)", referenced from:
      _main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Help please!
