I am trying to build a hello-world C++ application using Microsoft Visual C++.
#include <iostream>
int main() {
std::cout << "Hello, world. " << std::endl;
return 0;
}
I get this error:
main.cpp(1): fatal error C1083: Cannot open include file: 'iostream': No such file or directory
What are the standard include paths for Microsoft Visual C++?
Note: I am building from the command-line, not from Visual Studio
I actually just read through all of the documentation on this at: https://msdn.microsoft.com/en-us/library/ms235639.aspx
The material looks detailed and complete. If you get things configured like they require then it must work. They provide plenty of checks and conditions for ensuring that you are set up properly.
I am seriously suspecting that you aren't using a developer command prompt window.
I just did it myself and it works. Use Notepad and name the files like they tell you to do.
"Hello world!!"

i m trying to use sfml in my project using visual studio 2019. Following sfml documentation to perform setup for visual studio i have performed all the action required
i have included include folder in c/c++/additional include directory and also provided path for lib folder in linker setting and also provided additional dependencies in linker/input
but
#include <iostream>
#include <SFML/Graphics.hpp>
int main()
{
std::cout << "i cant tolerate" << std::endl;
return 0;
}
this code shows above mentioned error ,
cannot open include file 'Graphics.hpp' no such file or directory
it seems like include path is not working
how can i solve this issue
i tried many times but got same result
if anyone facing the same problem please check the platform in the project/properties win32 worked for my particular problem
I have found two similar questions this and this .
But they both use opencv, and opencv indeed provide the corresponding lib. I don't use opencv, and my project is very simple, just hello world.I have changed project default configuration like this
except for these configurations, others all take defaults
I just want to test my project configuration，that works find for win32 debug and release. But not work for x64 debug and release, they all tell me LINK : fatal error LNK1104: cannot open file 'opencv_world341d.lib'
I indeed know my project does not use any opencv lib, but why they tell me I need to use opencv_world341d.lib
my code
#include<iostream>
using namespace std;
int main()
{
cout << "hello world" << endl;
}
Thanks for everyone who comments on the question. I have solved the problem, although this problem not relevant to OpenCV to much, but I think the solution to the problem may be helpful to others. When I build project, visual studio 2019 tell me cannot link opencv_world341d.lib, so I go to Project->Properties->Linker->Input->Additional Dependencies , and I found opencv_world341d.lib. So I need to remove it, but it's readonly. From this we know visual studio using settings file (Microsoft.cpp..users.props) to control global settings including Global search path. These files are located at $(USERPROFILE)\appdata\local\microsoft\msbuild\v4.0 directory. Then I reedit Microsoft.cpp.<Platform>.users.props, delete opencv_world341d.lib, reboot visual studio, problem solved.
I have Abaqus CAE, Visual Studio 2017, Visual C++ compiler installed in my computer. I'm trying to reference Abaqus CAE's static libraries in my Visual Studio C++ project to read my ODB file.
This is the code file that I'm trying to compile & execute :
```
#include "pch.h"
#include <iostream>
#include <odb_API.h>
#include <odb_String.h>
#include <odb_Repository.h>
using namespace std;
int main()
{
cout << "Initializing API"<<endl;
odb_initializeAPI();
odb_String odbFilePath = "C:\\Users\\Dularish\\Desktop\\Temp_Toclear\\Job-1.odb";
try
{
odb_Odb& odb = openOdb(odbFilePath);
odb.close();
}
catch (odb_BaseException& ex)
{
cout << "Exception message : " << ex.UserReport().CStr() << endl;
}
catch (const std::exception& ex)
{
cout << "Default Exception message : " << ex.what() << endl;
}
cout << "Hello World!\n";
odb_finalizeAPI();
return 0;
}
```
Visual Studio Project Settings :
Platform : X64 (I'll not be able to compile with X86)
Configuration Properties > VC ++ Directories > Include Directories : C:\SIMULIA\Abaqus\6.14-3\code\include;$(IncludePath)
Configuration Properties > VC ++ Directories > Library Directories :
C:\SIMULIA\Abaqus\6.14-3\code\lib;$(LibraryPath)
Configuration Properties > Linker > Input > Additional Dependencies :
ABQDMP_Core.lib;
ABQSMAAbuBasicUtils.lib
.... and all the rest of the files present in the directory "C:\SIMULIA\Abaqus\6.14-3\code\lib".
With these settings, I'm able to compile it without any errors, but on execution of exe application,
I'm getting the below error :
"The procedure entry point ?openOdb##YAAEAVodb_Odb##AEBVodb_String##_N1VSMABasStringMode###Z could not be located in the dynamic link library ABQSMAOdbApi.dll"
Error Screenshot
Does it mean that I'm missing a static library containing openOdb method?
I'm trying to connect with people who are already familiar with Abaqus ODB C++ API who could help me on this.
Thanks.
Edit 1 : I don't want to use abaqus make utility because I want to build my own postprocessing application based on .NET platform. The lines "odb_initializeAPI();" and "odb_finalizeAPI();" are the lines which should be used if I want to access Abaqus ODB API outside Abaqus CAE. I'm actually following this page from the scripting documentation "http://130.149.89.49:2080/v2016/books/cmd/default.htm?startat=pt05ch10s07.html"
The other resource that guided me to use this approach : "https://www.reddit.com/r/fea/comments/8oqx5x/setting_up_abaqus_c_interface/"
There are at least two issues with your solution and approach:
The program you write must not contain a C++ main routine, aka the function main. Instead, the entry point for the program must be a function named ABQmain, having the same signature as the regular function main.
You must compile your Abaqus C++ code using the Abaqus make utility. Once you have finished writing your code and would like to compile it, the correct command to use is:
abaqus make job=your_code.cpp
If you have Abaqus on your machine, then you should also have the documentation. The section "Abaqus Scripting User's Guide" contains a section "Using C++ to access an output database." There you can find some examples and the details I've pointed out here. It should be a good starting point for your work.
EDIT: After pointing out that you wish to use the Visual Studio for development and compilation, make sure to check the system requirements for the Abaqus version you are using. Try to use the same Visual Studio C++ compiler as the one used for compiling Abaqus. Simulia is most probably using an older version of the Visual Studio C++ compiler than you are.
I keep getting this error with these lines of code:
include <iostream>
int main()
{
cout << "Hello World" >>;
system("pause");
return 0;
}
"The system cannot find the file specified"
The system cannot find the file specified usually means the build failed (which it will for your code as you're missing a # infront of include, you have a stray >> at the end of your cout line and you need std:: infront of cout) but you have the 'run anyway' option checked which means it runs an executable that doesn't exist. Hit F7 to just do a build and make sure it says '0 errors' before you try running it.
Code which builds and runs:
#include <iostream>
int main()
{
std::cout << "Hello World";
system("pause");
return 0;
}
The code should be :
#include <iostream>
using namespace std;
int main() {
cout << "Hello World";
return 0;
}
Or maybe :
#include <iostream>
int main() {
std::cout << "Hello World";
return 0;
}
Just a quick note: I have deleted the system command, because I heard it's not a good practice to use it. (but of course, you can add it for this kind of program)
I had a same problem and this fixed it:
You should add:
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64 for 64 bit system
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib for 32 bit system
in Property Manager>Linker>General>Additional Library Directories
Another take on this that hasn't been mentioned here is that, when in debug, the project may build, but it won't run, giving the error message displayed in the question.
If this is the case, another option to look at is the output file versus the target file. These should match.
A quick way to check the output file is to go to the project's property pages, then go to Configuration Properties -> Linker -> General (In VS 2013 - exact path may vary depending on IDE version).
There is an "Output File" setting. If it is not $(OutDir)$(TargetName)$(TargetExt), then you may run into issues.
This is also discussed in more detail here.
This is because you have not compiled it. Click 'Project > compile'. Then, either click 'start debugging', or 'start without debugging'.
I resolved this issue after deleting folder where I was trying to add the file in Visual Studio. Deleted folder from window explorer also. After doing all this, successfully able to add folder and file.
I was getting the error because of two things.
I opened an empty project
I didn't add #include "stdafx.h"
It ran successfully on the win 32 console.
I've reinstalled Visual Studio 2010 Professional several times to try to get it to work.
I had to uninstall Visual Studio 2012 Professional because it wasn't compiling something we did in class.
I completely uninstalled everything including SQL Server..
I went to VC/include and the iostream header file is not there.
#include <iostream>
int main () {
cout << "hello";
system ("PAUSE");
return 0;
}
This is all I'm trying to do because nothing else is working.
It's really driving me crazy because I need to get it working so that I can do my project!!!
Every time I do; new project => empty project => add an item to source =>.cpp
I'm running windows 8.
It just says Error cannot open source file
Also, error cout identifier is undefined....
I'm wondering if I should do a system restore?
Or if I should just completely reinstall windows 8 from my recovery media?
One problem is that you did not include the namespace std.
This is what your code should look like:
#include <iostream>
using namespace std;
int main (void) {
cout << "hello" << endl;
system("pause");
return 0;
}
or you could have done something like this: std::cout << "Hello" << std::endl;
This may be a problem because you did not set your environment to C++. This is how you do it:
Go to Tools > Import and Export settings. If you cannot find it, just search for it in Quick Search
Then go to reset all settings.
Then simply select "Visual C++"
Restart.
That should do the trick. If it does not, you might consider re-installing Visual C++ itself. For VS 2012. If that does not work, then re-install the program.
if it is problem with visual studio 2012, install this update.
