So I am trying to code C++ on Visual Studio Code. I am following a tutorial from youtube. https://www.youtube.com/watch?v=DIw02CaEusY&t=597s
When I get to 9:58 is where I loose track. He gets a message on his #include that says edit "InlcudePath" settings
I am doing the exact same thing as him and mine doesn't work. I am not sure why. I will show screenshots of his video and my code. I would greatly appreciate if someone could help me. Thanks!
This is the youtube video's image

You can follow this official tutorial to setup your VSCode environment, which is always up-to-date:
https://code.visualstudio.com/docs/languages/cpp
In short:
Open extension tab
Install "C/C++" extension.
Install compiler, depending on your OS:
Debian/Ubuntu: Install GCC using sudo apt install build-essential
Windows with BuildTools from Microsoft: Install Build Tools for Visual Studio 2019 from here: https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=16
Windows with MinGW: Install MinGW like in the video you provided.
macOS: Install XCode
Follow one of the tutorial to setup VSCode:
Windows with BuildTools from Microsoft: https://code.visualstudio.com/docs/cpp/config-msvc
Windows with MinGW: https://code.visualstudio.com/docs/cpp/config-mingw
macOS: https://code.visualstudio.com/docs/cpp/config-clang-mac
VSCode, depending on your platform should automatically find the compiler you have installed. You can try also to restart VSCode if can't find any.
You should see .vscode directory in your project,
VSCode will ask you if you want to create those files.
error related to path , i guess you have to set the path of mingw bin folder in path of enter image description hereenvironmental variables in system variable

I have netbeans IDE v8.2 . Im trying to create a C++ project. I dont have cygwin, but I have already installed MinGW, inside it, i have msys-make.bin, mingw32-gcc-g++.bin. Also, when i installed mingw, it came with nysys 1.0.
This is the tools options table:
However, it keep sending the message "no shell found. Cannot proceed. Please install either cygwin or mysys".
What is the solution for this?
We can solve it if we set as environment variables MinGW (C:\MinGW\bin) and MySYS (C:\MinGW\msys\1.0\bin).
This is my current setup:
#john I think that i solved it. Yes, minGW has msys 1.0, but i installed mysys standalone version in c:\ and netbeans worked with it. It now seems to work. Thanks.
I am struggling with build openh264 library in mingw . showing some error like nasm not INSTALLED ERROR found ..How to resolve the issues..
actually i want to add video settings in pjsip library for running call applications..
I have put command in mingw like >>make install .
Anyone know the issues or correct command to build the library.
Any help.thanks in advance...

I ran into this issue as well, and I had to install NASM on MinGW. The latest version of NASM wouldn't install for me, so I used this version:
https://www.nasm.us/pub/nasm/releasebuilds/2.12.03rc1/
I copied nasm-2.12.03rc1.zip and unzipped it to /MinGW/msys/1.0/nasm-2.12.03rc1/ from Windows Explorer, then I installed it using the steps here:
https://github.com/letolabs/nasm/blob/master/INSTALL
Within the MinGW shell, I then ran "cd /openh264-master/" and "make" to install OpenH264.
Hope this helps!
I'm currently struggling to build OpenCV for the UWP.
I already googled quite a lot and found Microsoft's OpenCV Github Repo which tecnically should do the magic. However, this repo and pretty much everything else I found in this regard are outdated (Visual Studio 2015, old OpenCV versions etc.). I need to use OpenCV 3.3 because it's a cross platform project and I don't want to recompile everything else solely because of an outdated git repo.
Can anyone explain the process of building OpenCV using CMake from the official repo for the UWP?
My first attempt was to simply use the Windows Dlls, however my application than shouts "Failed to load module" at me. Then, I tried to build OpenCV the Visual Studio Project files as stated here and here. However, this doesn't do it for me as it throws the following error:
CMake Error at cmake/OpenCVUtils.cmake:440 (if):
if given arguments:
"(" "OR" "OFF" ")"
Unknown arguments specified
Call Stack (most recent call first):
CMakeLists.txt:317 (OCV_OPTION)
It also tells me to check the CMakeOutput.log but there it's 0 errors everywhere.
If someone could tell me either how to get rid of this error or what to change in the CMake GUI to build OpenCV for UWP, that'd be great!
Edit:
I also tried to compile OpenCV with a platform specific toolchain for WinRT as found in platforms/winrt. It doesn't really change anything though (I'm not even sure if it should), I still get "Unable to load Dll: The specified module could not be found". Maybe GPPK is right in his assumption that it's more an UWP problem than an OpenCV one. Anyways, if anyone knows anything about this, I'd really love to get some help!
Ok, I didn't get an answer yet, so I managed to do it myself (more or less).
Here's how I did it:
Prerequisites
Visual Studio (2017)
UWP SDK
CMake
OpenCV from official repo
Steps
Create a build folder which you want the UWP libraries to built in.
Start PowerShell in this folder and execute the following command (exchange C:\OpenCV with your local OpenCV path): cmake -G "Visual Studio 15 2017" -DCMAKE_SYSTEM_NAME=WindowsStore -DCMAKE_SYSTEM_VERS
ION="10.0" -DCMAKE_VS_EFFECTIVE_PLATFORMS=x86 -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF C:\OpenCV
If you get the same error message as I did (see question for more details), go to the root CMakeLists.txt in the OpenCV folder and add a # in front of line 317 (OCV_OPTION(ENABLE_PYLINT)). This should fix it, to check, execute the command from above once more.
Ensure that the output claims "Windows RT support YES" and "Building for Microsoft platform: Windows".
Open OpenCV.sln in the build folder. Ensure that all projects are either of type "Windows Store" or "Universal Windows" and build the ALL_BUILD Project twice: Once in Release configuration, and once in Debug. Then build the INSTALL Project.
That's it, you should find the built Dlls in the install folder. Step 3 is probably a bug in OpenCV and will hopefully be fixed in upcoming versions.
I just installed Ubuntu 12.10, and I tried to install Eclipse and C++, but I failed miserably.
I started with an installation from the Software Center, Eclipse worked, but only in Java. Then I started googling for installation guides and tutorials, but after hours of downloads and installations, the C++ in Eclipse still doesn't work.
So now I have two questions:
How do I clean up this mess?
Actually, how do I know if there is a mess?
According to the Ubuntu Software Center, Eclipse is installed and has three add-ons.
How do I know if the other installations of other Eclipse versions/packagings overwrote each other or if I have multiple installations?
How do I install the latest version of Eclipse and C++ in Ubuntu 12.10?
There is a package called eclipse-cdt in the Ubuntu 12.10 repositories, this is what you want. If you haven't got g++ already, you need to install that as well, so all you need is:
sudo apt-get install eclipse eclipse-cdt g++
Whether you messed up your system with your previous installation attempts depends heavily on how you did it. If you did it the safe way for trying out new packages not from repositories (i.e., only installed in your home folder, no sudos blindly copied from installation manuals...) you're definitely fine. Otherwise, you may well have thousands of stray files all over your file system now. In that case, run all uninstall scripts you can find for the things you installed, then install using apt-get and hope for the best.
I used (the suggested answer from above)
sudo apt-get install eclipse eclipse-cdt g++
but ONLY after then also doing
sudo eclipse -clean
Hope that also helps.
I also tried http://www.eclipse.org/cdt/ in Ubuntu 12.04.2 LTS and works fine!
First, I downloaded it from www.eclipse.org/downloads/, choosing Eclipse IDE for C/C++ Developers.
I save the file somewhere, let´s say into my home directory. Open a console or terminal, and type:
>>cd ~; tar xvzf eclipse*.tar.gz;
Remember for having Eclipse running in Linux, it is required a JVM, so download a jdk file e.g jdk-7u17-linux-i586.rpm (I cann´t post the link due to my low reputation) ... anyway
Install the .rpm file following http://www.wikihow.com/Install-Java-on-Linux
Find the path to the Java installation, by typing:
>>which java
I got /usr/bin/java. To start up Eclipse, type:
>>cd ~/eclipse; ./eclipse -vm /usr/bin/java
Also, once everything is installed, in the home directory, you can double-click the executable icon called eclipse, and then you´ll have it!. In case you like an icon, create a .desktop file in /usr/share/applications:
>>sudo gedit /usr/share/applications/eclipse.desktop
The .desktop file content is as follows:
[Desktop Entry]
Name=Eclipse
Type=Application
Exec="This is the path of the eclipse executable on your machine"
Terminal=false
Icon="This is the path of the icon.xpm file on your machine"
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE
Name[en]=eclipse.desktop
Best luck!
I was in the same boat. Installed Eclipse, realized need CDT.
sudo apt-get install eclipse eclipse-cdt g++
This just adds the CDT package on top of existing installation - no un-installation etc. required.
http://www.eclipse.org/cdt/
^Give that a try
I have not used the CDT for eclipse but I do use Eclipse Java for Ubuntu 12.04 and it works wonders.
I'm trying to get eclipse to work with MinGW.
I've done the following:
Downloaded CDT for eclipse.
Installed MinGW.
Added C:\MinGW\bin to my path.
Opening a command prompt (CMD) and typing g++ or alike works fine.
I run eclipse, create a "New C++ Project", and only get the option saying "other toolchains".
There's a MILLION tutorials out there saying eclipse should identify MinGW on its own. It doesn't, and I don't know what to do. I've tried reinstalling everying in just about every order posible. Still no luck.
I've also noted some tutorials say something about creating a "Managed C++ Project". I've no such option, all I get is "C++ Project" and "C Project"
edit:
I have eclipse ganymede, windows x86_64, version 3.4.2
http://download.eclipse.org/eclipse/downloads/drops/R-3.4.2-200902111700/index.php
Running the "Eclipse IDE for C/C++ developers" fails, since there's no x64 version for windows. The x86 version requires x86 JAVA installed as well, and installing two versions of java, gave nothing but trouble in the past.
The instructions for setting up MinGW in Ganymede are located here.
The following are instructions and
links on how to install the current
version of MinGW. Note that these
links may become inaccurate over time
as new versions of MinGW components
are introduced. Please check the MinGW
File Release section for the latest
versions.
Download and run the MinGW setup program, MinGW-5.1.3.exe.
Select download and install the MinGW base tools and the g++ compiler.
You may select the Current or
Candidate version of these tools. You
may also install any of the other
available compilers as well.
Do not install the MinGW Make feature as the MSYS version of make
from step 5 is a more complete
implementation of make.
The MinGW setup program currently does not install the gdb
debugger. To install the debugger,
download the file from the following
location: gdb-6.6.tar.bz2
Extract the contents of the file gdb-6.6.tar.bz2 to the same location
where you installed MinGW.
If you want to use Makefile projects, download and run the setup
program from the following location:
MSYS-1.0.10.exe. MSYS provides an
implementation of make and related
command line tools. This is not
required for other types of projects
with the MinGW toolchain, which use
CDT's internal build tools to perform
the build.
Following this process resolved any problems I had.
I had the same exact problem with Eclipse Galileo and CDT 6.0.1. It turns out that CDT only recognized MinGW when it's located under c:\mingw. I had it in c:\msys\mingw so that was the problem. After I changed that everything worked fine.
The distinction between managed make projects and makefile project was removed in CDT 4.x, I think. Now there is only one type of project, but you can select different builders. CDT includes an internal builder which does not use makefiles and another one which does.
First, save yourself the effort of "reinstalling in every order possible". That is also known as trial-and-error, and will only make you more frustrated. Apply the normal problem-solving skills you have as a programmer.
Given that you have MinGW installed, what happens if you download "Eclipse IDE for C/C++ developers", start eclipse.exe, and try to create a C++-project with a MinGW toolchain?
EDIT: remember: the key in getting help with problems like these is to produce a minimal example which fails. Also, it would help if you provided URLs to the packages you installed (MinGW, Eclipse, etc.).
EDIT: I just installed CDT using the Ganymede update site, downloaded and installed MinGW from here, and restarted Eclipse, and everything worked fine. I know that doesn't help you, but it does prove that the toolchain detection isn't completely broken. Something is weird on your side.
You could try Wascana Desktop Developer. Its a distribution of Eclipse CDT configured specifically for developing on Windows.
I had the same problem (i.e. Eclipse not finding MinGW on the PATH) after I removed some of the unused files/folders from MinGW. It was ~600 MB and I was tasked to trim it down before adding to source control. I got it down to a workable ~200 MB. When I tried to re-create an Eclipse workspace afterwards, MinGW disappeared from available toolchains. It reappeared after I put the original MinGW install on the path.
