The following declaration is presenting a compilation problem using Xcode on OS X: ostringstream cmd; The error is as follow: Implicit instantiation of undefined template 'std::basic_ostringstream<char, std::char_traits<char>,std::allocator<char> >; The exact same code will compile and run on Linux - same imports and everything. What could be causing the issue?
View 2 RepliesI am trying to compile a program that uses ostringstream. I have included the following
#include <iostream>;
#include <sstream>;
#include <string>
as well as a bunch of other header files, but the rest of my program compiles nicely so I'll omit those for now. I have already tried
yum install gcc gcc-c++ kernel-devel
but everything is up to date. When I compile my program, I get this error:
GRASPv0.cpp:451: error: ostringstream was not declared in this scope
When compiling a C program i get the following errors.How do i modify the code to remove these warning messages?

A simple TCP based chat server could allow users to use any TCP client (telnet, for example) to communicate with each other. For this question you should consider a single process, single thread server that can support exactly 2 clients at once, the server simply forwards whatever is sent from one client to the other (in both directions). Your server must not insist on any specific ordering of messages as soon as something is sent from one client it is immediately forwarded to the other client. As soon as either client terminates the connection the server can exit

I had been working on a CPP code for sometime now, without being aware that some parts of its code, especially security related were not being compiled. Problem was like my product did not work for SSL mode. On analysis, I found that some part of CPP codes inside a switch(ENABLE_SSL_LIBRARY)were not getting compiled at all. And also that this gets set when we do newgrp crypto command on the box. This left me without lots of doubts. I wanted to understand how these switches work and if this switch was propreitary to my code or something related to Linux.
My questions now are:
1. Switches like the one mentioned above, are they user defined, for my particular code or are they related to Linux/GCC or makefiles?
2.If a user can define such switches to control code compilation, then need to know the concepts/procedures behind it. How is it done ?
Kindly excuse if these are very very basic. But since I could not get proper stuffs on google, I thought I should ask some experts here who could either explain me or point me to appropriate resources (links of articles / tutorials)

When I look for a Unix job I am often asked if I know C / C++, Perl or Java. Well, they mostly look for C / C++ + Unix or Perl / Python + Unix or Java + Unix combinations. That is the trend here in India. When they advertise for C / C++ + Unix they also mean Real Time System, Kernel (Modules), and Device Drivers Development. I don't know how to do those things in C / C++. But I must say that I love C / C++ and anything else no matter how attractive or easy it could be doesn't look that much challenging to me. So, which should I take now to add to my skills set and be more productive in terms of System Administration and Application Development and Support?
In C/C++ and Java, though I know them, I don't get to work in my current job. However, I often use Shell Script (Bash) and PHP and so I am finding Perl easy because the basics of Computer Programming that I learnt by learning C and C++ and Java have made it easy for me to understand any programming language.
