"No such file or directory" error in CodeBlocks

Question

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:
mingw32-g++.exe: error: CreateProcess: No such file or directory

Answer 1

Got it finally:

In my case, the problem resulted from a program called EGCS (Experimental/Enhanced GNU Compiler System). I installed it as a prerequisite for PSCAD(Power Systems CAD) along with a FORTRAN Compiler. Just remove it, and you'll be fine.
(Sadly, I deleted the entire PATH environmental variable due to a mistake. So what?...I ended up installing a new Win7 but after uninstalling my Ubuntu which again due to the Boot difficulties which resulted from uninstalling GRUB, I again ended up messing around with fixmbr and fixboot fellas(But I've lost my Laptop DVD!)...In summary, The EGCS laughed at me for a 0.5*MONTH...)

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.
