Is there any linux equivalent header files for windows in c programming for the following header files(linux)
#include <asm/uaccess.h>
#include <asm/system.h>
#include <linux/types.h>
#include <linux/kernel.h>
#include <linux/string.h>

When including a header file in stdafx.h, should that file still be included in the source file where it is actually used?
If it is included in both places, is the one in the source file ignored?
I have implemented MD5 checksum algorithm by using C language, but it is resulting correct value in windows but not in Linux?
// Constants are the integer part of the sines of integers (in radians) * 2^32.

0xd76aa478, 0xe8c7b756, 0x242070db, 0xc1bdceee ,

I am trying to detect keys pressed on a keyboard and mouse on both, Windows and Linux but I am unsure what would be the best practice way to do so. Will I have to detect the keys for each platform individually? Would you make use of an event listener? What's the best way to detect the input-devices?

View 3 Replies View RelatedI'm writing a server/client application in C++, one linux and one windows. The generic communication method is to use the boost::serialization package, but I'll also use a header to distinguish the type of the serialized string.
Here is the struct that the two programs communicate with
struct SerializeString {
std::string type_name;
std::string serialized_string;
friend class boost::serialization::access;
template<typename Archive>
void serialize(Archive& ar, const unsigned version) {
ar & type_name & serialized_string;
}
};
When one side wants to pass an object to another side, it uses typeid(T).name() for the field type_name. The receiving side receives SerializeString and checks its type_name against various acceptable structs as follows:
if (ss.type_name == typeid(XXX).name()) {
// deserialize ss.serialized_string to XXX and do something with it
} else if (ss.type_name == typeid(YYY).name()) {
// deserialize ss.serialized_string to YYY and do something with it
} else if (ss.type_name == typeid(ZZZ).name()) {
// deserialize ss.serialized_string to ZZZ and do something with it
} else {
// etc...
}
This worked fine when I was using Windows VS2013 on two different windows platform. However when I switch one to Linux there is a problem because their typeid(XXX).name() returns different things. So question here, is there a generic way to get some sort of unique names across platform / compiler? Or is my method reasonable at all?
how send and receive images from linux server to windows client?

View 2 Replies View RelatedI have a piece of code in C with header files included. I run it on Mac OS X Maverick with XCode 4.6.2 installed. GCC is also installed. Note that Command Line Tools in XCode are already installed.
When I compile it, the error I receive says something like this:
add.c:1:19: error: stdio.h: No such file or directory add.c:2:20: error: stdlib.h: No such file or directory add.c:3:20: error: unistd.h: No such file or directory
However when I run it on Ubuntu, it compiles without a problem.What to do?
So I've been making a header file and put variables in their own namespace to avoid conflicts. My question is, do functions in the header file normally go in a namespace too, or should they just be named in a way which makes them unlikely to be accidentally copied?
View 15 Replies View RelatedMy teacher talks about header files just having definitions and not declerations. I am writing a program that has a .h file and a related .cpp file along with a main.cpp it would be nice to have the .cpp file associated with the .h file compiled into an object file that would than just be referenced when the .h file is included. Am I making any sense?
View 2 Replies View RelatedI want to use two header files in my program. Here is exactly what I want to do.
-In the first header I have a binary tree and a structure.
-In the second file I have another functions that need to use the structure in the first header.
-I also want to use a function from the second header in the first.
-And finally I want to do actions with both headers in a "main.cpp" file that contains only int main() function.
How to include the headers in each other and in the main.cpp to be able to do the actions above?
I try to include the first header in the second one and the second one in the first header. Then I include both headers in the main.cpp file. But the compiler shows me many errors.
I have two header files, A, B.
A.h
namespace test {
struct info
{
int a;
}
}
B.h
#include "A.h"
int main {
test::info.a = 10;
}
However, it has an error. I don't quite understand how to use namespace.
I'm working with CGAL - Computational Geometry Algorithms Library, which is a library of geometry functions declared as several thousand header-only files. When I run a basic program (source code [URL] ) I get this output: [URL]
I have tried switching angle brackets to quotes. I have also started reading up on CMake.
Do I need to walk the dependency tree and add all of those files to my CMakeLists.txt? Or is there a way to tell the compiler to look in subdirectories?
I have some header files with generic functions. And in one of them, I define TRUE and FALSE. Recently I started using another header file and it defined TRUE and FALSE as well. That caused GCC to throw an error, and not compile. In my case I can put #IFNDEF around the values so that if it is already defined they don't get defined again, but is there a better way to handle duplicate names? I assume the case would be the same for duplicated functions, how does that get handled?

View 4 Replies View RelatedSo say I create a header file which contains a list of structs, and I want to use these structs through out my source and some of my classes... how would I accomplish this?
When I try to do it via #include, I get re-definition errors, due to the nature of #pragma once. If I switch to #ifndef then I lack defenitions in files other than the source.
Is there a way to define things such as structs across multiple files, which doesn't lead to re-definition errors, and doesn't involve manually re-created all the structs for each file?
I'm having with header files, specifically to do with the string data type. The objects work perfectly when I put them inside the .cpp but when I set it to include the exact same code in a .h, I get a string of error messages.

I'm working on trying to figure out constructors and header files. Can ya'll help me out with this? I'm sure my code looks like a mess as I tried to piece together different solutions I've found. There's also an attempted copy constructor and operator function. Basically my problem is my source file says there is no default constructor for my class type. Here's my header code:

I currently have a running program "game.cpp" that runs a game of tic tack toe. I want to split the working functions into header files so that game.cpp isn't so cluttered. I have created two header files "displayBoard.h" and "gamePlay.h" but they wont compile because the functions are looking for variables that haven't been declared. First, here's the working code.
#include "displayBoard.h"

this is my header file used in both cpp file
#ifndef SUM_H
#def SUM_H
int sum(int x,int y);
#endif
error i am getting in main cpp in devc++

msdos is present on my computer but it cannot include the header files but when i check all files are present but they still cannot include????????
