I installed code::blocks before but I have never encountered a problem during the execution of a hello world program, which everyone must be familiar of. Today, I installed code::blocks along with GNU compiler and added it to PATH (environment variable). Everything seems right, but when I run the below code, it showed an error:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}
(I build and run the code and the messages are as follows)
Project/Target: "FileTest - Debug":
The compiler's setup (GNU GCC Compiler) is invalid, so Code::Blocks cannot find/run the compiler.
Probably the toolchain path within the compiler options is not setup correctly?!
Do you have a compiler installed?
Goto "Settings->Compiler...->Global compiler settings->GNU GCC Compiler->Toolchain executables" and fix the compiler's setup.
Tried to run compiler executable 'C:\MinGW/bin/gcc.exe', but failed!
Skipping...
Nothing to be done (all items are up-to-date).
I don't quite know what this log meant. I installed MinGW and when I went to Settings / Compiler, it just showed that I am using MinGW. Everything seems right.
Here is a screenshot from my editor:

Anyone help me?
It says the code::blocks can't find the compiler. So, naturally it will be invalid. Try uninstalling the code::blocks IDE & from the site of code::blocks install the minGW setup. I am giving this link, see it works or not.
https://sourceforge.net/projects/codeblocks/files/Binaries/20.03/Windows/codeblocks-20.03mingw-setup.exe/download
I had the same error, It was a Environment error,
Download the mingw-setup.exe file from Code::Blocks ide.
Install
Go to Settings -> Compiler -> Reset Defaults

I haven't been able to compile c++ programs on vscode (or any IDE for that matter) and I can not for the life of my figure out why. This happened after I factory reset my computer due to other issues. Everything was working fine until then. I re-installed gcc through MinGW and checked that it is installed by typing gcc in command prompt. I can even compile programs through command prompt, which proves that gcc is installed. I would much prefer to use code though, and I was wondering if anyone knew why code is complaining about include paths.
Here's an image of the relevant file with the paths
ANY HELP IS GREATLY APPRECIATED!!!

I am a total noob at programming and IDEs. I am attempting to open a project for some research that I am doing. I have a Macbook Pro using Mac OS High Sierra 10.13.6.
The project that I'm trying to open is a c++ project, but every time I open it, there are error messages everywhere. It appears that the header files aren't even being recognized. A screenshot is linked below. From what I've read so far, the issue seems to be that I don't have a proper debugger for c++. I downloaded XCode after I downloaded Eclipse like some guides have recommended, but it still hasn't fixed the issue.
Other sources I've found on this site use highly technical language (Eclipse GDB MacOSX Mavericks), so I'm struggling to figure out how to fix the problem. If anyone has any ideas, I'd love to hear them.
Here is a better solution for beginners.
Create a file called HelloWorld.cpp
and copy paste the following inside:
#include <stdio.h>
int main(int argc, char **argv)
{
printf("Hello world\n");
return 0;
}
Then open your terminal ( like that ) and write this:
$ g++ -g -o main HelloWorld.cpp
If this goes smooth it means you have gcc installed (good!).
After that try to run this:
$ gdb ./main
If this goes smooth it means you have gdb installed (great!).
Move to create a new Eclipse project with this file only
and update your post if there are any problems.
If this goes smooth gradually migrate your stuff to HelloWorld.cpp.
If gcc or gdb steps above fail, you have to install them first.
There are many online guides on how to do that. Good luck!
I am by no means a Mac expert or do I know much about eclipse CDT or Xcode but I can offer what I know. This is not a complete answer but I just want to share as I also know what it is like to struggle with C code on OSX.
First,
You need to make sure the C/C++ compilers are installed on the Mac properly. They come with XCode and I believe the compiler is Clang. Then you need to make sure the standard libs were installed correctly.
That whole issue is your first problem and should be asked to an XCode programmer and what not.
Second, to use eclipse CDT you need to tell it where and what compiler you are using. As well as the linked and debugger. You can do this in the project properties or settings. The stuff should usually be put in the path variable but once eclipse CDR knows where to find all that and everything is installed correctly it should pick up the header files and then include them in every project!
That’s all I can really provide you and I hope you can find out more.
G++ fails to compile simple "Hello World" code.
Platform details are in the Title
I have tried to run from both VS Code ("insiders" version 1.26.0), and from the Windows command-line /terminal.
Neither route will return an *.exe file
This is the C++ code. VSCode Intellisense doesn't show any errors (C++17)
#include <iostream>
using namespace std;
int main()
{
std::cout << "Fresh New World" << std::endl;
return 0;
}
At the Windows command line (terminal) I've used the command
g++ -o FreshWorld.exe FreshWorld.cpp
This command does not return an error, nor does it return the desired *.exe file (I've even resorted to SEARCHing all the folders)
Running this in VSCode (1.26.0) also does not return an error.
I had run this code in the previous stable release (pre- "June 2018") VS Code, and it compiled properly. The problems started immediately after the update to Jn2018. I've worked with VS Code developers (that's why I'm running the "insiders" version) but, as we now know, the problem also exists at the command-line (terminal) so not confined to VS Code.
Any ideas??????
I am entire newbie to C++, MinGW, and to VS Code so this has become an insurmountable hurdle to further experimentation and learning!
Lots of things could be causing this:
Antivirus: it could be intercepting the gcc executable (they tend to dislike other compilers due to the way a compiler generates executable code etc.). Try disabling the antivirus and test again.
Your MinGW(-w64) installation is broken. Try reinstalling. Where are you getting your GCC? I strongly suggest using something like the official MinGW-builds for MinGW-w64 here or a package management system such as MSYS2.
Wrong environment settings. Your provide little details of how and what you are doing (how are you starting the command prompt interpreter, how is your PATH set up, etc.).
Without more details, I can't determine what is going wrong for you. Please edit your question to provide these details.
I've just installed the most recent version of mingw32 and trying to compile even a hello world c++ program fails.
Installation was in the default C:/MinGW directory. I chose the option to install with mingw-get gui, and I selected the Basic Setup tab on the left-hand column, marked the mingw32-base and mingw32-gcc-g++ options for installation. Then I applied changes and downloaded all the files. Lastly I added C:/MinGW/bin to the path of windows.
Now I create a file that looks like this:
test.cpp:
#include <iostream>
int main() {
std::cout << "hello world!" << std::endl;
return 0;
}
and then I compile with g++ test.cpp
Now, the problem is a bit harder to diagnose. When I execute the output a.exe file, the command line simply hangs, no output, no return. If I try and cancel execution with ctrl-c, nothing happens. When I forcefully exit out of the command line, and try to delete a.exe, windows tells me the executable is currently opened by system, and the only way to forcefully remove the file is with FileASSASSIN.
Some notes, I have visual studio 12 installed, but nothing pertaining to it in the path. I had a previous installation of cygwin64 but it has been removed entirely. I get the same behavior running it from powershell, normal command line, or Console2. Google suggested I try statically linking libstdc++ with -static-libstdc++ to no avail.
Also, when compiled with debugging symbols and then ran with gdb a.exe, and then you run start, it also hangs just the same.
I'm out of ideas on getting information for troubleshooting here. Does anyone have any insight?
On the suggestion of #M.M, I discovered that avast antivirus was the silent cause of halting any executables made by mingw32. This was puzzling, because I was running executables made by visual studio on command line only a few hours ago.
The lesson: If you encounter unexpected behavior, always try your antivirus.
I'm a new user of MinGW, and I have already run into problems. When attempting to compile a very simple Hello world c++ program, I get an error. I type the command:
g++ hello.cpp -o hello.exe
and then I get the message dialog:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: c:\mingw\bin\...\libexec\gcc\mingw32\4.8.1\cc1plus.exe
R6034:
An application has made an attempt to load the C Runtime library incorrectly.
Please contact the application's support team for more information.
followed immediately by this message dialog:
cc1plus.exe - Program error
The application failed to initialize properly
(0xc0000142). Press OK to close application.
And then the usual junk about Windows finding a solution online.
I used the automatic installer mingw-get-setup.exe and simply followed the instructions. I chose the installation folder to be C:\mingw, and in the MinGW Installation Manager, I chose to install mingw-developer-toolkit, mingw32-base, mingw32-gcc-g++, mingw32-gcc-objc and msys-base. As suggested in the installation guide, I added PATH in the Environment Variables.
The code I was trying to compile was:
#include <iostream>
using namespace std;
int main(int argc, char ** argv){
cout << "hello world" << endl;
return 0;
}
I also tried to compile a similar ANSI-C code with the command:
gcc hello.c -o hello.exe
and I got the same error.
I tried the command in cmd.exe as well as in MSYS and got the error in both cases. My operating system is Windows Vista Home Premium, and I have Microsoft Visual C++ 2010 installed on it. I mention this because I tried to do the same installation on a windows 7 computer without VC++ and here the compiler worked without problems. Does this mean that you can't have MinGW and VC++ on the same computer?
The problem was, as suggested in the comments, that programs other than the Gnu Compiler had left values in the %PATH% variable. What I did not initially notice, was the fact that there are two %PATH% variables, one for the user and one for the system, and both can interfere with the MinGW installation.
The system %PATH% variable contains (at least on my PC) quite a lot of entries and removing all of them might not be a good idea. In my case, however, it was sufficient to remove entries from MatLab and Texnic Center. Afterwards, g++ and gcc worked flawless.
