"No such file or directory" error in CodeBlocks

Here is the steps I followed in CodeBlocks IDE:

Create a new project->console->C->Name->debug and release->finish

So when I choose `main.c` and build it, It should show the "Hello World!", but I get this weird `mingw32-gcc.exe: error: CreateProcess: No such file or directory` error.

I've written and compiled about 20 C files this way, but I don't know what has recently happened to the IDE.

I've checked the CodeBlocks forum and googled this problem;No results
Any ideas?

**Bulid Log:**

-------------- Build: Debug in C (compiler: GNU GCC Compiler)---------------

mingw32-gcc.exe -Wall -g -c "C:...\Project Files\C Codes\C\main.c" -o obj\Debug\main.o
mingw32-gcc.exe: error: CreateProcess: No such file or directory
Process terminated with status 1 (0 minutes, 0 seconds)
1 errors, 0 warnings (0 minutes, 0 seconds)

I used CodeBlocks 10.02 three days ago and it compiled and ran the code successfully. It showed this error yesterday. I thought that maybe the code file wasn't included so I removed the previous code from the project and added the new file (I do like this for about 20 programs and always get results); but the error still exists. Then I rebuilt the project but still got the error. I uninstalled ver.10.02 and installed a new version 12.11 today. Again I get this weird error.

P.S. It looks like someone else have had this problem too:

Codeblocks seems to be calling gcc correct -- I'm not seeing anything wrong with the way it's being invoked. The error message you're getting:

>gcc.exe: error: CreateProcess: No such file or directory

indicates that there is something wrong with your installation of mingw-gcc. Since you said that this was working previously, that likely means some files required for gcc to function are either corrupted, inadvertently renamed, moved elsewhere or accidentally deleted.

In fact, I was able to reproduce that exact error by renaming `cc1.exe`. This is the C compiler that gcc needs to able to compile a C source file. On my install for Mingw-4.6.3, this resides under `./libexec/gcc/i686-w64-mingw32/4.6.3`. Yours may be different depending on which mingw version and variant you're using.

I recommend downloading and reinstalling your copy of gcc altogether since fixing this manually can be tricky.

Got it finally:

The answers here failed to solve my problem! My friend got it fixed for me. The solution was pretty simple and straight forward. The problem that occurred was that compiler couldn't chain itself with the MinGW (Minimalist GNU for Windows) which could have been modified by some other make files for makefiles softwares like CMake etc. So the solution is:

1. Open Codeblocks and in the top Tool Bar select the Settings option and under that select the compiler option.
2. It will open the Compiler Setting Window. Here select the Global Compiler settings(with a Gear Symbol) and in the sub-options select the Toolchain executables option.
3. Under this select the Compiler's installation directory. Here browse files to select: C:\Program Files(x86)\Codeblocks\MinGW\bin
4. Now select the Auto-detect option on the right.

It should solve your problem and I hope you got an understanding of what the problem was!!! Happy Programming!

I just solved this error. Probably I got this when I moved a file accidentally which was under execution in C-Free IDE. All you have to do is ,locate the g++.exe file in your Program files. Just go through the program files of the particular IDE and find mingW folder and locate the 'g++.exe'
inside it.

This usually happens when the compilers PATH in Codeblocks is not a valid one. In my case it was pointing to C:/MinGW. Which Codeblocks found out using its auto detect feature.

To get rid of the error you need to change the path back to the one that is present within the Codeblocks program folder.

In my case it was - C:\Program Files (x86)\CodeBlocks\MinGW.

You can change the path in Codeblocks by following these steps.
Menu bar-> Settings-> Compiler-> Toolchain Executables.
Then enter the corresponding valid compiler directory path.

Hope this solves your problem.

I still had a problem with that error. Turns out it was there beacause I had MinGW installed externally before installing CodeBlocks.

In that case check if your directory path (explained how to change it above) isn't `C:\MinGW\bin` but instead `C:\Program Files (x86)\CodeBlocks\MinGW\bin` since it may cause the error to pop up.

After two days of struggle, I confirmed the solution from codesavory and Anand MP.

All the reason is the Toolchain Executables. I finally found that it was cygwin's path!

After I change to D:\GreenSoft\CodeBlocks\MinGW, it compiles ok now!

I think the problem take place at the install step: codeblocks detect everywhere on your PC to find a existing gcc, and let you choose one as your favorite. It even forgot that the installer is already bundled with a minGW!, and it does not show where the detected gcc are located! So if you simply confirm one and forget it, it will abandon the bundled minGW.

Open command line and type in:
```
mingw-get update && mingw-get install mingw32-gcc
```
This will download the missing GCC files.
