I want to do conditional compilation based on whether it is windows 7 or windows 8. Here is the code below.
#if (_WIN32_WINNT >= 0x0602) //Condition to check whether it windows 7 or 8 .Based on this we can load msxml 3 or 6.
#import <msxml6.dll>
#else
#import <msxml3.dll>
#endif
Im building the above code in windows 8 machine.
Issue here is _WIN32_WINNT should have a value 0x0602, it means it is running in windows 8 machine.Instead it has a value 0x0601 (Means it is taking windows version as windows 7 defined in sdkddkver.h).Im not sure after installing windows 8 sdk im not able to see any include or lib files in the path below C:Program Files (x86)Microsoft SDKsWindowsv8.0A . but i can see all include and lib files of sdk version v7.0A available although i did not installed it.
I'm developing C++ application in visual studio 2012. I have couple of C++ projects in my solution. I have put some library paths in every project's properties ( i.e ,Config properties - > C/C++ - > Additional Include Directories and Linker - > Additional Include directories ).I developed in debug mode, if i change to release mode, all library settings gone.Is there any possibility to retain all settings when change to debug to release mode and vice versa ?

Have a program which given a C source code file, gives back RAW MACHINE CODE, which means it doesn't have to be a executable on his own.
Like:
Given a example function for C:
int stdcall Function(void)
{
return 0;
}
Gives back the Machine Code for the Example Function.
It doesn't need to be actual C code, it can also be like:
type int
return 0
Or also it can be a straight assembly-to-machine-code compiler.
Is there any Library? Or even a external tool I can look into?
Code:
class A
{
public:A(int a, int b);
};
I need to have an object of class A that doesn't have a default constructor in another class, B:
Code:
class A; //This is in a separate header file
class B
{
private:A a;};
The problem is that it won't compile without a default constructor. I'm not allowed to define a default constructor, and the A object in class B has to be private so I can't initialize A a in public.
I also can't change the prototype in the interface to something like
A(int a = 0, int b = 0);
since one of the requirements is that if an object of class A is declared in main, it must not compile due to not having a default constructor. So what can I do to make class B work and compile?
Another question I have is why is this valid:
Code:
class A; //#include "A.h" is in the implementation file so it compiles.
class B
{
private:A* a;}; But not this: Code: class A;
class B
{
private:A a;};
This is for a project that I probably won't be able to turn in on time, but I care more about how to do this right than turning it in for full points.

#include <cstdlib>
#include <iostream>
#include <fstream>

Considering this small code:
Here a template array class is written and also a cat class. The cat class has "present" method.
the array is initialized with 20 cats. yet, trying to activate a cat methods makes a compilation error:
Code:
#include <iostream>
using namespace std;
template <class T>
class Array{
private:

how do we make it work? I'm sure there's a way I'm not aware of since if we can't - what is the point of templates?
I am working on one application that requires extensive logging so I want to create a log file of each day during execution.
I tried easylogging++ but i am unable to use into multiple files. If i try to use in other file. I get compilation errors of using same functions or methods already defined.
How can i use macro to hide the implementation of logging in one class to other ??
I've been writing a game engine in C++ for a little over a year now, and its been really fun so far. I've been focusing on windows support for now (using Visual Studio and MSVC) but I'd like to leave the possibility of Linux and Mac support open. As a test, I recently compiled a small portion of my reflection system in Clang, to make sure it all still worked (since I consider that the most advanced portion of my codebase, though I'm pretty sure its all standard C++11). Anyway, I got some strange errors regarding undefined identifiers in template functions, and I managed to isolate the issue in the code below:
#include <iostream>
#include <string>
using namespace std;
template <class UserType>
string DoSomething() {
return TypeInfo<UserType>();
[Code] ....
Clang throws an error about 'TypeInfo' being undefined when 'DoSomething()' is compiled. However, MSVC compiles the code above without so much as a warning.
This goes against my understanding of how template functions/classes were compiled. I always thought that Undefined symbols were not an issue in templates, as long as they were defined by the time the template was instantiated. Whats the issue here? If in fact MSVC has been doing some non-standard stuff, that's pretty unfortunate for me if I want Linux support, as I'll have to do some serious backflips to resolve all the issues with this in my headers and stuff (I can't be the only one in thinking the current state of C++ with headers and forward-decelerations is just awful to work with).
This is my question : Define a class named HOUSING in C++ with the following descriptions:
Private members
REG_NO integer(Ranges 10 - 1000)
NAME Array of characters(String)
TYPE Character
COST Float
Public Members
-Function Read_Data( ) to read an object of HOUSING type
-Function Display() to display the details of an object
-Function Draw Nos( ) to choose and display the details of 2 houses selected randomly from an array of 10 objects of type HOUSING Use random function to generate the registration nos. to match with REGNO from the array.
Now I' trying to do this by this way
Code:
#include <iostream.h>
#include <conio.h>
#include <stdlib.h>
class housing {
private:
int REG_NO;
char NAME[10];
[Code] .....
I am trying to pass the entire array of object in DrawNos(). but getting compilation error -
32: 'housing:rawNos(housing * *)' is not a member of 'housing'
48: Structure required on left side of . or .*
What is the problem? How can I pass the array of object in function and use it.
Today I experienced a very strange compiler issue. I started the compilation and it outputted that a member object of a class was undefined. After about 4 hours of trying the find the bug I commented and then uncommented said line of code that was undefined. Sure enough the compilation worked just from commenting and uncommenting.
I am using Microsoft visual studio 2012 express. Due to the size of the project, I should know the cause because it may cause more problems further down the line. I feel that it might have something to do with the compiler not having a proper order of compilation for the header files and that I might need something to solidify the way that the header files are processed. The below code is a fragment of a header file.
class CInGameSection: public CBaseGameSection {
public:
CInGameSection(bool isInEditor, bool creatingNew, COutput& output, string saveSlot, string regionName, horiVertiVals * widthAndHeight);
~CInGameSection();
bool update(CInput & input, CAudio & audio, COutput & output);
void output(CInput & input, CAudio & audio, COutput & output);

I'm parsing a text file, and I'd like to detect when a certain Compilation Condition - i.e. #ifdef - begins. The challenge is, that the condition can take any of the following patterns:
#ifdef (FLAG)
#if defined (FLAG)
#if (defined (FLAG))
(And perhaps I missed more)
I'd of course need to treat them all the same, as they are indeed the same. How would you know to treat them all the same?
I am trying to write a generic linked list in c, but for some reason i keep getting errors saying "incompatible pointer type. This is the code and erros:
#ifndef SLIST_H
#define SLIST_H
#include <stdlib.h>
typedef struct {
void *data;
slist_elem *next;

Code:
#include <stdio.h>
main() {
int c, n1;
n1 = 0;
while ((c = getchar()) != EOF)
if (c == '')
++n1;
printf("%d", n1);
}
I have a more complicated program I'm wishing to have display the output, however, to save some time I'm using an example of a shorter version. count the lines in input and display the output in terminal when ./program is executed after compilation. To count and compute lines, words and within arrays.
I'd like to compile following code:
Code:
sigfillset( &sa.sa_mask );
sa.sa_handler = &CDevice::PipeHandler;
sa.sa_flags = 0;
sigaction( SIGPIPE, &sa, NULL );
sa.sa_handler = &CDevice::TerminatorHandler;
sigaction( SIGQUIT, &sa, NULL );
sigaction( SIGINT, &sa, NULL );
Using MSVC 2010 to run on Windows 7. Is it possible?
Here are the libraries included:
#include <iostream>

#include <cstdlib>
#include "stat.h"
And heres the line being flagged:

The error I receive is one discussed on a number of different forums:

It just seems to me theres a lot of conflicting information about if this is even possible to do on Windows and when I do try work around functions or calling double drand(void) I get a ton of errors. I'm hesitant to try rand() or something less precise. I was hoping maybe someone would be able to maybe suggest a compiler which will run this or a different library, right now I'm using Code Blocks IDE.

Basically I want to embed the QGIS canvas widget into a custom application. In order to do that, I need to build QGIS from it's source in order to obtain the devel *.lib, *.dll, *.h, etc. files required. To that result, I am trying to build either version 2.6.* or the current nightly build ~2.7 - 2.8 64 bit version. There is very little documentation on the x64 builds. Not to mention that CMake and I are not the best of friends.
My progress so far:
- Successfully built the extremely out of date nightly build readme instructions of version 0.11 x86
- Partial success in creating CMake output to VS2010, but many required headers were not included such as gqsmapcanvas.h, (So even if I got it building I couldn't use the canvas widget in an application)
*Note I updated the external packages to x64 versions, so it is not an architecture mismatch issue.
I have also had issues with QWT looking for QWT Polar header files, but I suspect this is another issue with the missing headers as most of the errors related to files contained in the original source from GIT.
