So, I am a total noob at C++ and I need serious help. I bet for some average users this is not even a problem, so please help me.
I wrote this in Visual Studio Professional as a Win32 console file.
#include <iostream>
using namespace std;
int main()
{
int i = 100;
return 0;
}
And in the console I get the following:
1>------ Build started: Project: Project1_RenatoAlegre, Configuration: Debug Win32 ------
1>Build started 1/25/2012 3:09:03 PM.
1>InitializeBuildStatus:

I have no way of running the program because of this "1 failed" something. I must run the program in Visual Studio Professional.
Project properties -> C/C++ -> Linker -> System -> SubSystem: Console (/SUBSYSTEM:CONSOLE)
If you want a console project.
Please change the subsystem in your linker settings from Windows to Console.
Right click on the Project name in the Solution Explorer
Select Properties
Open Linker in Configuration Properties
Subsystem will be the first item on the list.
Select Console (/SUBSYSTEM:CONSOLE) on the dropdown

recently I've installe SFML for Visual studio 2015. I have read the tutorial for this specific task on there web site but after the test (compiling and running debug) this error show up:
https://pastebin.com/mY7r7zy9

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
why and what should i do ?
should i rename my main.cpp to winmain.cpp ?
thanks you for the help
P.S: VS2015 is one the main drive where the OS is (C:) but SFML the folder is on another drive (E:)
If your subsystem is set to Windows (/SUBSYSTEM:WINDOWS), you need to link sfml-main, which will define WinMain() and call main().
If your subsystem is set to Console (/SUBSYSTEM:CONSOLE), then you don't need to link sfml-main.
To change the subsystem, go to your project settings, then Properties -> Linker -> System -> SubSystem
I feel like this question should have been asked already but I haven't been able to find any solutions to accomplish this. But basically I'm going through the youtube lecture videos for Stanford's CS106B course on C++ and I'd like to use their libraries in my Visual Studio 2010, but i'm a VS newbie so I'm not sure how to get the include to work. I've tried to include the path to Project|Options|Include Directories but I get the following error

Update: I downloaded the library from here: http://stanford.edu/~stepp/cppdoc/
And i'm using the Visual Studio IDE.
Any assistance would be awesome, and then I'd know how to include external libraries!
Hi I have been having problems with Microsoft VS.
When I try to run simple code such as:
#include "stdafx.h"
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
cout << "hello" << endl;
return 0;
}
I get an error message saying:
"Unable to start program 'C:\elevator\Debug\elevator.exe'.'
the system cannot find the file specified"
This message has been coming up for a long time. I do not believe it's any problem with my code. My program will be compiling fine then all of a sudden this error will come up without me even changing the code. I have tried uninstalling and re installing VS which didn't work. I have also spent a long time searching Google for the solution to no avail.
This is the output I get when trying to run the above code:
1>------ Build started: Project: elevator, Configuration: Debug Win32 ------
1>Build started 26/02/2014 14:49:21.

Maybe you have an anti-virus that detects your new program as problematic, and puts it to quarantine as soon as it is compiled.
I think I've found a solution for some C++ projects in vs2010. If you are using 'incremental linking' you will have this "fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt". In my case I've swiched it to "No", and now project compiles and run without any problem.
If you want to try go to: Project Properties -> Configuration Properties -> Linker (General) -> Enable Incremental Linking -> "No (/INCREMENTAL:NO)"
about "Incremental Linking": http://msdn.microsoft.com/en-us/library/4khtbfyf(v=vs.100).aspx
This is the message I get
Unable to start program C:\Users\Documents\Visual Studio 2010\Projects\EULER'S Fixed\Debug\EULER'S Fixed.exe
The system cannot find the file specified.
Here is the Build Output

You have missed to define main:
int main()
{
//..
return 0;
}
You get that message when you fail to save all before the first compile.
I consider it to be a defect in 2010. Creating a new project, or adding files to a project or deleting files from a project don't actually save. You have to manually save before they are really there.
Select the properties for the file in which main is defined and make sure "item type" under "General" (under Configuration Properties) is set to "c/c++ compiler"
Well, I just got the new MSVS 2010 Beta 1, and just like with 2008 express, I just can't figure out how to compile anything, not even a simple hello world program. Anyone have any pointers? I usually just get a blanket fail message. No real information.
Edit: Sorry about that
#include <iostream>
using namespace std;
main()
{
cout << "hello world";
return 0;
}
I go to build and I get:

Edit #2. How exactly would I go about changing it to multibyte?
That's a well known problem with VS10 Beta. You need to change the default encoding to Multibyte from Unicode to make it work.
int main() maybe ?
Try also changing the destination of the project to something simpler and not that long since I believe I also had the same error when the destination was too long.
Also did you choose a console application when creating the project?
If that didn't help, google gave this as possible answers too :
"You could try going to your
project's Properties > Configuration
Properties > Manifest Tool > Input
and Output, and set your "Embed
Manifest" option to "No"."
"I had a similar problem like this a
few months ago and I solved it by
going to project -> properties ->
Configuration Properties -> General
-> Character set. Under character set I changed it to Use Multi-Byte
Character Set and then my compliment
issue went away."
Edit:
In regard to the latest error link here directly from microsoft. I'm afraid that from this point on it's google time as I'm all out of ideas if it doesn't work.
The link says : "As a workaround for Beta1 you can change the entry point to use "wmain" instead of "main" or change the character set of your project to use "Multi-Byte Character Set""
Easiest would be to just change the name of main to wmain then.
Ok, I got it to compile using a win32 console ap, changing to Multibyte, and using the following code:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello World!";
return 0;
}
Now to try to figure something else out. I'm not used to VS so...
Thanks everyone.
