Using code::blocks w/o a project

[dukester]

noob to the *blocks" here!
noob to C as well.
I want to simply compile a single c source code file, without having to go through all the project file stuff etc - like in emacs & geany etc.

Is it possible with code::blocks? TIA ..

Yep, just create a file in a temp folder like:

Code

#include <iostream>
int main() {
std::cout << "Hello World! Welcome to your first C++ program!" << std::endl; }

and name it HelloWorld.cpp (no spaces)

Start CodeBlocks and use Menu/File/Open or just ctrl-o keys
and hit the compile icon (the gear icon).
Click on the "Build log" tab to make sure no errors occured.
Clik on Menu/Build/Run.
You should see a console open with "Hello World! Welcome to your first C++ program!" as output.

Easier than that is:
Load Codeblocks and do:
If you get messages like: "HelloWorld already exists, do you want to overwrite it?", answer yes.
1) Menu/file/new/project...
2) Double click "Project application"
3) Click on "next" two times. Enter the name "HelloWorld" (no spaces)  in the project title.
4) Click on "next" and "finished"
5) On the Project tab double click "main.cpp" to open the file.
Cl6) Cick on the compile (gear icon) to compile, then  Menu/Build/run (or the  green right-pointing run arrow).

I found an even easier way to create the file.
Menu/File/new/Empty file.
Paste the code into the file.
Menu/File/Save as/ c:\temp\HelloWorld.cpp (or any other folder, as long as it's not a protected OS folder.
Menu/Build
Menu/Build/Run

[dukester]

I did just as you suggested - opened an existing .c source file.
Build & run

I keep getting:

||=== Build file: "no target" in "no project" (compiler: unknown) ===|
||=== Build failed: 0 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

Menu/Build
Menu/Build/Run

Right on! Thx, but I still get that error msg from code::blocks.

What OS and what version of CodeBlocks are you using?
show us your hello world code inside codetags  (the # above a reply box).

You must install and configure a compiler.

Make sure that your Menu/Settings/Compiler/ToolChain_executables look like this:

Thx for the screenshot!! Yup! Got it set up that way also!
I have zero probs from the CLI / emacs / geany. Compiles like a charm. I just got the notion to test-drive code::blocks! Too much grief it seems.

I just tried your above suggestion for hellery! No joy!
The main.c file got written to the HelloWorld directory, BUT /obj/Release/main.o never gets written so gcc chokes with an error msg.

/usr/bin/bash: gcc -Wall -O2 -Wall -std=c99 -m64 -Og  -I~/programming/c/code/HelloWorld -I~/programming/c/code/HelloWorld/ -c ~/programming/c/code/HelloWorld/main.c -o obj/Release/main.o: No such file or directory

What version of CodeBlocks are you using?
Should show in the splash screen, but you can find it in the Menu/Help also.

Tomorrow, I'll load up Codeblocks in a Linux VM and see what's going on.

Hang in there, bud. You're gonna like CodeBlocks. 

I've been using it for Windows, Linux, and embedded coding for 20 yrs. I know any new software is hard to get started using. After that, it flies.

We'll figure this out. I just need to cause the same problems you're having to understand what's going on.

[dukester]

Right on! I'm close to the solution I'm sure!
I've got v20.03 on this Linux antiX box!

Thanks for all your help!

I brought up (in a VMware) Linux Mint 21.x:
Name             : Code::Blocks
Version          : 20.03-r11997
SDK Version      : 2.0.0
Scintilla Version: 3.7.5
Author           : The Code::Blocks Team
E-mail           : info@codeblocks.org
Website          : http://www.codeblocks.org
wxWidgets Library (wxGTK port)
Version 3.0.5 (Unicode: wchar_t, debug level: 1),
Runtime version of toolkit used is 3.24.
Compile-time GTK+ version is 3.24.33.

I disabled all plugins except: (via Menu/Plugins/Manage Plugins)

I restarted CB after disabling plugins.
I performed the following.
1) Menu/File/New/EmptyFile
2  copy/pasted your code into the Untiled1 editor.
3) Menu/File/Save as/ into Home/pecan/temp/HellowWorld.c
4) Menu/Build/Build
5) Menu/Build/Run

 The results are in the .jpg attached.

WOW! I'll try disabling all plugins as well except those you kept - and try again. Thanks a bunch for the trouble you went through!
