wxWidgets 2.8.12 Compile Error

Following the directions at:
http://wiki.codeblocks.org/index.php/Installing_Code::Blocks_from_source_on_Windows

I removed the C:\TDM-GCC-64\bin; path from Windows 7 PATH variable. I added the paths C:\MinGW\bin;C:\MinGW\mingw32\bin;
I attempted to compile wxWidgets 2.8.12 so that I could compile the latest SVN version of Code::Blocks.

I executed this command sequence in Windows 7's cmd.exe terminal emulator:

--- Code: ---cd C:\wxMSW-2.8.12\build\msw
mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1  clean
mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1
--- End code ---

The compilation ended with this error:

--- Code: ---process_begin: CreateProcess(NULL, g++ -c -o gcc_mswudll\monodll_dummy.o -O2 -mt
hreads -DHAVE_W32API_H -D__WXMSW__ -DNDEBUG -D_UNICODE -I..\..\lib\gcc_dll\mswu

ll\monodll_dummy.o.d -MD -MP ../../src/common/dummy.cpp, ...) failed.
make (e=2): The system cannot find the file specified.
makefile.gcc:4717: recipe for target 'gcc_mswudll\monodll_dummy.o' failed
mingw32-make: *** [gcc_mswudll\monodll_dummy.o] Error 2
--- End code ---

Where did this go wrong?

Miguel Gimenez:
This happened to me some years ago. IIRC this CreateProcess issue occurs only when you are mixing MSYS and CMD environments. Also recheck your path (you can remove C:\MinGW\mingw32\bin). When changing the path (in the desktop) you must close and reopen the CMD window for the change to take effect.

I was using CMD aka Window 7's terminal emulator. So I tried it in MSYS. In the MSYS terminal emulator I did this command sequences:

--- Code: ---export PATH=$PATH:/c/MinGW/bin;
export PATH=$PATH:/c/MinGW/mingw32/bin;
cd C:/wxMSW-2.8.12/build/msw
mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1  clean
mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1

--- End code ---

Compilation terminated with the same error.

Have you verified the "g++" command exists?

The command:

--- Code: ---g++ --help
--- End code ---
gets the expected response. The error it terminates on appears after many successful executions of the g++ command. So for sure it does exist.

From what I can interpret of the error message there is a file it seems to expect named  dummy.cpp that it cannot find.
