Programming :: SDL Static Library - Shared Library ?
Apr 7, 2009I'm reading about shared, static, and dynamic libraries. What is SDL? Is it static, shared, or dynamic?
I always thought a library would be a lot of .h and .cpp files compiled separately into .o files and then if you compiled your own program you could use the -l parameter to link the library and it was all compiled together. Now I'm not so sure.
I don't even see any SDL .cpp files in my system anywhere. All I have are lots of SDL .h files in /usr/include/SDL and I don't really understand the code in them.
I'm making a wild guess here: SDL is a shared library. SDL itself is NOT compiled into my program, therefore SDL must be on any system my program tries to run on. When I compile and link SDL all it needs is the header files to know what SDL function and objects it can use. And then on every system it uses an already compiled SDL shared library thingy somewhere.
So... where is that part of SDL? All I can find are header files.
I'm thinking the advantage of shared libraries is that someone could say update SDL on their own system and take advantage of the new features without having to download new executables with the new version of SDL compiled into them for every program that uses SDL.
So if I'm making an editor and a game engine and they both use a lot of the same .cpp and .h files that I wrote and I'm tired of updating one and then the other and I need to turn them into a library, then a shared library might be kind of a silly solution. I could just make a static library. Right? Because it's not SDL. Nobody else is ever going to use this library.
Programming :: Convert A Dynamic Library (filename.so) To A Static Library (filename.a)?
Nov 18, 2009How can we convert a dynamic library (filename.so) to a static library (filename.a) using gnu gcc . Can we get a static library form a dynamic library . I saw a few post in which the conversion form a static library to a dynamic library is mentioned but, unfortunately, not the other way.

Jul 4, 2011I am attempting to write a server application in C on a linux machine which listens for TCP connections and transfers data. I am trying to detecton the server side when the connection is broken. The closest thing that I got to work was looking at the return value from sending data. For example the server�s job is to mainly read data from the socket but to test if the connection is still up the server sends data periodically back to the client. I look at the return value from send() to determine if the connection is broken e.g.
Code:int ret = send(session->clientSocket, &data[sentCnt], count - sentCnt, MSG_NOSIGNAL)I found that this does not immediately return an error when the connection is broken. The reason for this is because even though the connection is broken send() is still successful because it is able to put it on the network buffer. To fix the issue I did the following things;
Code:
//set send timeout
struct timeval timeout;

Programming :: PHP - Connection To Remote Server To Edit File?
Mar 14, 2010I have a webGUI in php where users can make certain settings. How can I edit a file on a remote server from my php webserver? Currently I use my FTP client, vsFTPd and a chrooted user in a specific directory where the file resides. I think this is pretty save as long a nobody else uses my FTPclient. How can I make changes to this file on the remote server from within my php-code on my webserver ?? (so that not I need to make the changes but my users can do it from a html-form) I found this but the credentials for the FTP-connection are plain :
<?php
$file = fopen ("ftp://loginasswd@server", "w");
if (!$file) {
echo "<p>Unable to open remote file for writing.
";
[code].....
I use https for the webGUI, but I guess this does not mean the connection to the remote server will be encrypted also ? Can I use my FTP-user (has no shell) from within php to edit the file ?

May 20, 2011I have a general question regarding php. Suppose that I want to have an array that stores connection-specific data, that can be anything IP address or something similar. However, whenever I use global or server variables (i.e. GLOBALS or _SERVER) the array created in this way is kind of connection-oriented, so that for each connection there is a separate instance of this array. Maybe it has something to do with the MPM of Apache, but I am not sure. Is it possible to implement an array that stores information about all connections that are at a system? In this way, each connection can chip in and upload it with data? Also, I would rather not use cookie's.

Apr 18, 2010How to make simple games (snake, pong... nothing too fancy). I have completed making snake and now want to be able to distribute it. I built it using C++ and wxWidgets so it would be multi-platform. I'm able to compile it and run it in both Windows and Ubuntu using g++. In windows, I was able to distribute it by putting a *.dll file in the same folder as the executable. However in Linux, I don't understand what I need to do so that it would run on any installation of Ubuntu out of the "box". When I build it and try to run it in a different installation of Ubuntu (which has g++) it gives me an error saying that a particular library file was not found and Getlibs fails to find that library file.
Is there a way to build a project with G++ so that all the dependencies are either packaged in the executables or copied into the folder....?

CentOS 5 Server :: PHP SOAP Server Returns Array Using NuSOAP Library?
Jul 2, 2009I have a function in my SOAP server that returns an array. When the client calls this function, it only receives "array", and when I use foreach to print each member of this array, it tells me that this is not an array. If I change the returned value of the function to a string or integer type everything works fine though, so I don't think that there is any problem with the client.I am using NuSOAP library on php to achieve that.I had doubt when declaring the type of return value of the function. In XML schema there is no array type, so I specified the return value as a string like this:

I'm using g++ 3.2.3 on a Linux AS v3update6 machine.
