Can you tell me how to install GTK on windows 10 or have a step by step guide, all the ones I've tried have not helped me.
Possibly if someone also explain how to compile from cmd or prepare an IDE (code: block maybe).
Any commands I mention should be run at the MINGW shell, found here: C:\msys64\msys2_shell.cmd
First update msys2 with pacman -Syu
Make sure you have installed GCC...Install the required toolchain for GCC with pacman -S mingw-w64-x86_64-toolchain. When using pacman, just keep typing enter if prompted to follow through with the installation and get back to the command prompt.
In order to set this step up with Code:Blocks, make sure you go to the Code:Blocks menu Settings->Compiler, and the menu Toolchain Executables. From there, put in the msys2 installation directory and where you installed MinGW's GCC compiler (for me this was putting C:\msys64\mingw64) under the compiler's installation directory option. Also edit the C Compiler path under the same menu to x86_64-w64-mingw32-gcc.exe.
Next, in order to install gtk+3.0, use the command pacman -S mingw-w64-x86_64-gtk3. Now the latest version of GTK+3.0 will have been installed, so it is time to set it up with Code:Blocks.
Open Code:Blocks and create a new C file. You may definitely write your code in Code:Blocks, but I do not suggest that you compile it from there. Two compile, go back to the MINGW shell. Type nano ~/.bashrc to edit it. You may scroll down using the arrow keys to the bottom of the file and add: PATH=$PATH:/c/msys64/mingw64/bin. Restart the MINGW shell and open it back up.
Finally, try running:
gcc source.c -o executable.exe `pkg-config --cflags --libs gtk+-3.0`.
If that command doesn't work, I would suggest using the i686 version of gcc installed in MINGW.
I hope this helps!

the screenshot shows what the empty field and the code writtenI have just set up VS Code for programming with C, I installed all the necessary things (gcc, gdb..etc)
But when I started writing basic code, vs code shows an empty output after I run it
Installation (Ignore if installed)
Windows
Install mingw/gcc/clang compiler and then add it to the path.
GNU/Linux
Install gcc/clang compiler using your package manager.
Arch Based Distros: `sudo pacman -S gcc`
Ubuntu/Other debian based distro: `sudo apt install gcc g++`
Now, install C/C++ extension for VSCODE here's the link C/C++ extension
Installing the C/C++ VSCODE extenion
Or you can directly install it through Ctrl+Shift+P and paste this snippet ext install ms-vscode.cpptools.
Compiling
Now, open your terminal in VSCODE and run gcc Test.c -o test and then run ./test to execute your program.
Or, if you have installed clang compiler then the terminal command goes here clang Test.c -o test and then run ./test to execute your program.
Main method have return type int, try return 0; after printf. Or you need to add argument to main method, in java program i know we can not run program without argument.
Or
Try make void main method
I am using Codeblocks and have to run an OpenMP C program. So, I added the flag -fopenmp in Codeblocks (compiler settings) and am now getting the error of 'mingw32-g++.exe: error: libgomp.spec: No such file or directory'
So after a bit of searching on the internet about the error, I downloaded TDM-GCC ( installed in C:\TDM-GCC-64). But still the same error is being shown on Codeblocks.
What am I doing wrong?
Here is the build log:
mingw32-gcc.exe -c "D:\Language Files\MatrixMultiplication.c" -o "D:\Language Files\MatrixMultiplication.o"
mingw32-g++.exe -o "D:\Language Files\MatrixMultiplication.exe" "D:\Language Files\MatrixMultiplication.o" -fopenmp
mingw32-g++.exe: error: libgomp.spec: No such file or directory
There are multiple possible causes for this: Either you did not install OpenMP with the compiler or you made a mistake in the Code::Blocks configuration. Anyways go through the following steps and you should be able to fix it. You seem to be working on Windows but I also added remarks on how to do it on Linux.
1) You will need a compiler that comes with OpenMP. For Windows download TDM-GCC preferably the 64-bit executable (second file) and install it. Make sure you select OpenMP in the component tab: Components > gcc (TDM current: ....) > OpenMP (the last entry). Linux already comes with GCC so just open the command line and get yourself OpenMP by typing sudo apt-get install libomp-dev in the terminal.
2) You will have to configure the Compiler in Code::Blocks now: Go to Settings > Compiler under Selected Compiler select GNU GCC Compiler and click Copy and type in a convenient name for your new compiler such as TDM-GCC Compiler. Go to Toolchain executables and browse the directory for all the Program files (C compiler, C++ compiler, Linkers, Debugger, Resource compiler, Make) you should be able to find them in C:\TDM-GCC-64\ ...\bin on a Windows machine if you chose the default installation. I can't tell you the precise sub-directory as I working on a Linux machine but you should be able to find it pretty easily. Depending on your installation there might be two folders for 32- and 64-bit. For Linux this step is not necessary.
4) Then you need to set the Linker settings. This can be done for all projects (which I would not recommend) by doing the following steps in the aforementioned menu or for your current project by clicking Project > Build options. Go to Linker settings of the corresponding configuration (Debug or Release) and click Add under Link libraries. On a Windows machine you will need to browse a file called libgomp-1.dll (32-bit) or libgomp_64-1.dll (64-bit) which should be located in the same folder as the aforementioned Program files. Under Linux instead choose -lgomp under Other linker options.
3) Set the compiler flag -fopenmp (for all the projects or only the current one) by going to Compiler settings > Other compiler options and typing in there -fopenmp.
4) Test it with a program like the OpenMP "Hello World".
I am very new to coding (trying to teach myself C). I have some experience with MatLab, but I understand it is very different from C. I have Windows 10 with the newest version of Visual Studio Code (VSC) with the Run Code Extension and git extension (not sure what git does, but VSC prompted me to install). I am now familiar with the text editor, but do not know how to compile/run my code (apologies if I'm butchering the terminology, again, a newby). One friend recommended I determine the location in which the desired text file is located, type "gcc filename.c", enter, type "./a.out", and then the program should run. (Said friend has a Mac and I supposed the execution commands are different?) Regardless, I encountered "Run Code" extension on my google adventures and follow the steps I've seen online, but I am still getting the error pictured.
I can see how this would be an especially basic question, but if anyone can offer assistance/advice, I would be extremely grateful!
Thanks, All.

P.S. In case the image doesn't load/work for whatever reason, this is the error:
"'gcc' is not recognized as an internal or external command,
operable program or batch file."
Works perfect in Visual Code. You need the following:
C/C++ extension in Visual Code.
msys64 installed in C:\
Add path to msys64 bin folder in environment variable
Instructions:
https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools
Important the msys64 path doesn't contain spaces so don't install it in Program Files.
You can search "Edit system environment variables" from the windows button, press button Environment Variables, and then add it as a System variable "Path". For me its located in
C:\msys64\mingw64\bin
Hey,,,
It will work for you I believe
Blockquote
First: open the link: https://www.msys2.org/
Go to the installation and download the installer .. install the exe file.
search mingw in windows search(windows start)
there is an app named--> MSYS2 MinGW {64/32}-bit
run it as administrator
Found command shell ---> type: pacman -Syu
Will ask you for some installation click on Y
Then again go to the same app MSYS2 MinGW {64/32}-bit and run as admin
and write--> pacman -Ss gcc (in shell that opend after click)
after clicking there will be bunch of things and now you have to care about your windows arch.. if it is 64 bit then write---> pacman -S mingw-w64-x86_64-gcc (and if its 32 you will find something like that where 64 will replaced by 32 in bunch of commands that are showing in your shell)
after executing this command gcc will be installed in your system to check write: gcc --version || g++ --version
After that to install the debugger write pacman -S mingw-w64-x86_64-gdb
to check write: gdb --version
**Every thing got installed in your system now find the mingW file or mysys2 file on C drive(whereever you r mingW file got saved) go the the minGW 64 || 32 accroding to your operating system there is a bin folder click on that and copy the path inside the bin folder and save it in environment variables path **

Enjoy vs code
My recommendation
You are on Windows right? So you can just install Visual Studio IDE (follow this tutorial). Which is better than vs code. This tutorial is for C++ but it works for C as well. Because C++ uses the same compiler as C but with some more things(simple explanation).
The solution for your problem
You are getting the massage 'gcc' is not recognized as an internal or external command, operable program or batch file because you do not have the gcc compiler installed on your computer. But if you want to install it, you can follow this tutorial. But I highly recommend you use Visual Studio IDE which I mentioned above.
Type gcc --version in the command prompt to check whether the C compiler is installed in your machine.
If it is installed then try adding gcc to the environment variables using this link:
https://www.youtube.com/watch?v=qLh84CmdBJ0
If it is not installed then install it using instructions using this link:
https://www.guru99.com/c-gcc-install.html
and then add it to the environment variables using the link above.
If it is installed and not recognized by VSCode then try to run VSCode from CMD by typing code in CMD.
I downloaded atom a couple of days ago and I can't seem to find the right package or where and how you compile the program.
does anyone know?
Now, it's possible to run and compile (also debug) C and C++ program from within atom editor.
Install gpp compiler package in atom editor.
Prerequisites:
Windows:
You'll need to install MinGW and add it to your system PATH.
Mac:
You'll need to install XCode.
Linux:
The GNU Compiler Collection may come with your distribution. Run which gcc g++ to find out.
To compile and run: F5
To debug: F6
Atom is "simply" a Text editor that is not able to compile anything. If you use a Makefile, then there are a few add-ons for building targets via key bindings.
If not, open a terminal and use the C compiler on your system. On Linux/Unix machines you probably want to use gcc:
gcc <your_source>.c -o <output_name>
EDIT
Or take a look at This Package
here's a link for atom gnu gcc compiler-- https://atom.io/packages/gpp-compiler
1. download it
2. place the file in atom's package folder
3. press F5 on atom editor to RUN n Compile your file.
it will open text.ext as a output.
i have installed the cygwin package for my netbeans IDE. I can use that in netBeans project. But now I want to use the gcc compiler from a cmd prompt. How can I do that?
In Linux we open a terminal and type
gcc filename.c
and it compiles. Now I want to do the same thing in Windows with Cygwin's gcc. Can I type gcc filename.c in cmd and it compiles? If so, how?
Edit :
by writing in cmd
gcc --version
I get Access is denied
Edit 1:
In the C: drive I have a folder named Cygwin that contains Cygwin.bat.
When I run that, a new prompt is opened and inside that when I type gcc filename.c, it works.
In that .bat file :
#echo off
C:
chdir C:\cygwin\bin
bash --login -i
I don't understand what that means.
I see from your latest comment that it works when you run gcc from the Cygwin bash shell.
The Access is denied message was appearing when you tried to run gcc from the Windows cmd prompt. I don't know why you'd get that particular message.
My advice is just to use the bash shell. (It also has a lot of nice features that the Windows command shell lacks.) If that's a good solution for you, feel free to stop reading now.
But if you really want to use Cygwin tools (such as gcc) from a Windows prompt, you need to update your Windows %PATH% to include the Cygwin bin directory. As seen from bash, the directory is /usr/bin/; from Windows, it's going to be something like C:\cygwin\bin (assuming you installed Cygwin in C:\cygwin, which is the default).
To permanently add C:\cygwin\bin to your Windows %PATH%, open System Properties in the Control Panel, tap the "Environment variables" button, and adjust the value of Path in "System variables". Once you've done that, newly opened cmd windows should have the new %PATH% setting. (The user interface for modifying environment variables isn't exactly use-friendly; maybe somebody else can suggest a better way.)
EDIT:
The cygwin.bat batch file changes the current director to C:\cygwin\bin and then launches the Cywgwin bash shell in a new window. That gives you an environment in which gcc works by default, since your $PATH is already set up correctly. The windows command shell and the Cygwin bash shell are quite different environments.
If you installed the gcc package for cygwin, you should be able to do simply gcc filename.c.
The setup.exe file of Cygwin lets you choose any additional package you want to add when installing. If you skipped it, simply rerun the setup.exe.
Packages can be also found on the Cygwin website.
does your cmd recognizes gcc as an installed application?
if so, try this
gcc -c filename.c -o filename.o
gcc is actually a link (which the Command Prompt does not understand). Use gcc-3 or gcc-4 if you need to use the Command Prompt.
