I wrote the following on a notepad and save it as hello_world.cpp in the following folder: C:\cplusplus
#include <iostream>
main(int argc, char* argv[])
{
std::cout << "Hello World\n";
return 0;
}
I brought up cmd.exe and executed the following code to compile the cpp file.
C:\Program Files (x86)\CodeBlocks\MinGW\bin>g++.exe C:/cplusplus/hello_world.cpp
-o hello_world.o
However, I got the following error message:
g++.exe: error: CreateProcess: No such file or directory
I wonder if someone could point out what I did wrong.
Thank you!
I think the problem is "/" which is used in Linux. In Windows is "\".
Try:
C:\Program Files (x86)\CodeBlocks\MinGW\bin>g++ c:\cplusplus\hello_world.cpp
-o hello_world.o
To run your C++ code in Visual Studio Code using the MingW g++ compiler, you can simply use the following steps:
Make sure you are in the same directory you save your C++ file
Next, use this command to create the executable file of your code:
g++ -o hello_world hello_world.cpp
Here, the "hello_world" will be the name of your executable file which you wish to provide and "hello_world.cpp" is the name of your actual C++ source file.
This will create your executable file, then finally use the command:
./hello_world
This will run your executable file.
The instructions do say to re-login after setting MingGW up. I'd reboot, just for good measure.

I did a clean install of MinGW on Windows 7 32bit with the GUI Installer, and installed
ming32-base-bin
mingw32-gcc-g++-bin
msys-base-bin
When trying to compile a simple "Hello World.cpp" from the cmd.exe i get the error:
C:\Users\Lorenzo\Desktop>g++ "Hello World.cpp" -o"Hello World.exe" -m32
g++: fatal error: cannot execute 'cc1plus': CreateProcess: No such file or directory.
compilation terminated.
The weird thing is that by grabbing the file from the desktop and putting it over g++.exe (so that i open the file with the application) in the MinGW directory, i don't get any error.
A temporary fix i found was to have a new environmet variable pointing in the folder where cc1plus is (C:\MinGW\libexec\gcc\mingw32\9.2.0). The program runs but doesn't include the libraries from C:/MinGw/lib and C:/MinGw/Include, i have to include those manually, which shouldn't occur (i guess).
I don't want to do this crude fix since i know i'll encounter some other problems with time.
Ok. I found the solution with some luck.
It is as simple as adding .exe to g++
> g++.exe *input file* -o*output.exe*
Don't Know if it's a bug or not, but this works for me.
I'm not sure which MinGW you used exactly, but it's better to use MinGW-w64.
There is a standalone build you can get from http://winlibs.com/ that doesn't require installation. The site also gives some instructions on how to use it.
I am just trying to run a basic program in notepad++ and mingw32. I have attempted multiple different thing but I continue to get.
Current directory: \\THEBOX\Users\jacks_000\Documents
C:\MinGW\mingw32\bin\g++.exe -g "testpgrm"
CreateProcess() failed with error code 2:
The system cannot find the file specified.
================ READY ================
When I run the nppexec I use the following
NPP_SAVE
CD $(CURRENT_DIRECTORY)
C:\MinGW\mingw32\bin\g++.exe -g "$(FILE_NAME)"
I have also tried:
NPP_SAVE
CD $(CURRENT_DIRECTORY)
C:\MinGW\bin\g++.exe -g "$(FILE_NAME)"
I am just using a basic test program:
#include <iostream>
using namespace std;
int main()
{
cout<<"Hi";
return 0;
}
I don't know if I will have issue running it in the command prompt if I save it this way or if I have done something wrong. I am running Windows 10 if that is a issue.
Current directory: \THEBOX\Users\jacks_000\Documents
I think it's because g++ can't access to a SMB share.
Try to compile the file locally.
The problem is with the location of "C:\MinGW\mingw32\bin\g++.exe". Where it is on your PC, and what is the actual filename, will depend on your installation.
For example, on my machine I have and old version in "C:\Program Files (x86)\CodeBlocks13_02\MinGW\bin\mingw32-g++.exe", but a newer installation in another folder.
So you need to find the executable name and location of the compiler. You won't need to use the top two lines, just "C:\Program Files (x86)\CodeBlocks13_02\MinGW\bin\mingw32-g++.exe -g test.c", for example.
I did this and it gave a result of :
C:\Program Files (x86)\CodeBlocks13_02\MinGW\bin\mingw32-g++.exe -g test.c
Process started >>>
<<< Process finished. (Exit code 0)
================ READY ================
I am trying to compile code using gcc and run the executable, but it is throwing error:
gcc somefile.c -o somefile
compilation goes through successfully. But, when I try to execute it:
$sh somefile
It results in: Syntax error: "(" unexpected. Among the output files, I dont see somefile.o, but instead, I see somefile.c~
The contents of the file:
#include <stdio.h>
int main(int argc, char *argv[])
{
printf("hi");
}
Context: I am new to programming in linux, and wanted to start out with simple programs. I am running ubuntu 64 bit on a virtual machine, with gcc, g++, etc installed. After that I created a sample file as mentioned above ("somefile.c"), and tried the steps mentioned above, but could not execute. My goal is to compile and execute a sample C or Cpp code on ubuntu using gcc or g++. Please help.
your somefile is executable binary, it's not shell script. you should execute it by:
$./somefile
To execute file you just have to do
$./somefile
sh is used when you've to execute a shell script
I am new to Linux Ubuntu 11.10 and have basic C++exposure.
I installed the g++ by
sudo apt-get install build-essential
and created a directory cpp in my home directory. I then wrote a program hello.cpp in my cpp directory
#include <iostream>
using namespace std;
int main() {
cout << "Hello !" ; return 0;
}
and compiled using
g++ -W hello.cpp -o hello
The program compiles without any errors/warnings. When I try to execute the file
./hello.cpp
I get error messages:
line 3: using: command not found
line 6: syntax error near unexpected token `('
line 6: `int main() {'
I tried looking at a lot of posts but could not resolve this. I have MS VisualStudio on Windows, but I would rather learn C++ on Ubuntu. Thanks in advance.
I think that the problem is that you're trying to execute the .cpp source file rather than the generated executable. Try running ./hello instead of ./hello.cpp, since hello is the actual executable. The errors you're currently getting are caused by the shell interpreter choking on C++ syntax, since it's trying to run it as a shell script.
Hope this helps!
I'm trying to compile a C++ project (Hello World) in windows 7 using Eclipse Helios. After creating the project the console shows me the next message:
Internal Builder is used for build **
g++ -O0 -g3 -Wall -c -fmessage-length=0 -osrc\hello.o ..\src\hello.cpp
g++ -ohello.exe src\hello.o
c:/mingw/bin/../lib/gcc/mingw32/4.5.0/../../../../mingw32/bin/ld.exe:
warning: auto-importing has been activated without --enable-auto-import specified on the command line.
If I open the command line and execute: g++ hello.cpp -Wl,-enable-auto-import, I can generate the exe file and I can run it.
In eclipse after adding the argument "-Wl,--enable-auto-import" in the MinGW C++ Linker - Miscellaneous section, I didn't get any warning however, the console is always empty. Again, using the command line, if I move to the directory and execute the exe file generated by eclipse I get the expected result.
I know that Eclipse is compiling the cpp file properly but, why the eclipse console is not displaying the info? Is something missing in the configuration?
Sorry guys my stupid question.
I appreciate your help.
This looks like an environment variable(s) and/or register paths problem.
