    55A: You're using the wrong shortcut to open MSYS. See the note at the bottom of [wiki:WindowsMinGW/current#MSYS the "MSYS" section in the installation guide].
    66
    7 === Q: When I use the "cm" (or "cmake") command, I get an error ===
    8 
    9 There are multiple errors with multiple reasons. Sometimes this can be solved by closing (all instances of) MSYS and/or rebooting Windows. If this doesn't help, compare your error message to the examples below:
    10 
    11 ==== A1: "cm" alias is not defined: ====
     7=== Q: When I use "cm", I get "sh: cm: command not found" ===
    128{{{
     9$ cm
    1310sh: cm: command not found
    1411}}}
    15 If your error looks like this, you have to define the "cm" alias as explained here: [wiki:WindowsMinGW/current#BuildOrxonox].
    1612
    17 ==== A2: CMake is not installed / not in PATH ====
    18 {{{
    19 sh: cmake: command not found
    20 }}}
    21 If you get this error, CMake is not installed properly or it is not added to the environment variable PATH. Please refer to [wiki:WindowsMinGW/current#CMake the guide] for an explanation.
     13A: If you get this error, you have to define the "cm" alias as explained here: [wiki:WindowsMinGW/current#BuildOrxonox].
    2214
    23 ==== A3: MinGW not installed properly / MSYS not correctly configured ====

    36 If CMake prints an error like this (and about 30 more lines), the GCC compiler was not found. Make sure you installed MinGW and MSYS properly by following [wiki:WindowsMinGW/current the guide]. You can also open the file {{{c:\<msys-install-path>\etc\fstab}}} with a text-editor (WordPad, Notepad) and check if the path to MinGW is configured correctly (default is {{{c:/mingw /mingw}}}).

    53 If CMake prints an error like this (and about 20 more lines), you probably missed to install g++ with MinGW. Please refer to [wiki:WindowsMinGW/current#MinGW the installation guide] and ensure you selected "C++ Compiler" in the installation menu of MinGW.
    54 
    55 ==== Note ====
    5619Note that if you're using a sane installation of MinGW and the other tools (as explained in [wiki:WindowsMinGW/current the guide]), you should be able to use {{{cmake}}}, {{{gcc}}}, and {{{g++}}}. You can check this in the MSYS console:
    5720{{{
    … …  
    6528g++.exe (GCC) 4.5.0
    6629}}}
    67 The actual output may differ, but you shouldn't get any errors.
     30The actual output and versions may differ, but you shouldn't get any errors. If one of the three tools can't be found, refer to the according question ("xxx": command not found).
     31
     32If all three tools seem to work, but you still get an error using "cm", refer to the questions below ("CMake complains about xxx").
     33
     34=== Q: "cmake": command not found ===
     35{{{
     36$ cmake --version
     37sh: cmake: command not found
