Maybe I found why cc.exe isn't found

    I'm not sure if it's a bug but I found this link: https://github.com/Alexpux/MINGW-packages/issues/1030

    which leads to this other one: https://github.com/Alexpux/MINGW-packages/pull/1034

    Looks like some MinGW versions don't download cc.exe, this is what files "The GNU C Compiler" lets you download:

    These are my dirs that I added to the "Path" env variable: ";C:\Users\Francesco\AppData\Local\Programs\Python\Python35\;C:\Users\Francesco\AppData\Local\Programs\Python\Python35\Scripts\;C:\MinGW\bin\"
    The dirs are correct while installing SCons:
    C:\Users\Francesco\AppData\Local\Programs\Python\Python35\
    C:\Users\Francesco\AppData\Local\Programs\Python\Python35\Lib\site-packages\

    The first link I sent says that they corrected the bug? But it doesn't look like that to my MinGW, which is on the version "0.6.2-beta-20131004-1".

    Are you unable to compile tpt? If you are still able to compile without cc.exe, I can remove / change the section of the wiki guide that tells you to run it.

    testing cc.exe isn't required at all, it's just a simple test to ensure MinGW installed correctly.

     I stopped where the wiki says: 'If instead you get "cc: command not found"'

    Should I try to continue even if it says command not found?

    Yes, please continue the guide anyway. If MinGW isn't including cc.exe then that will always fail, even when MinGW is really installed.

     I arrived to the last section, it says: "Now to compile, run scons.py".

    I cannot found scons.py here: https://github.com/simtr/The-Powder-Toy

    I didn't clone it, I downloaded the zip, the only py there is generator.py, other than SConscript and SConstruct.

    I guess I should open generator.py from IDLE and run it?

     

    EDIT: If I use scons.py directly into the Git Bash, it says: "scons: *** SCons version 2.5.1 does not run under Python version 3.5.1.
    Python 3 is not yet supported."

    If you added everything to your path (which you did), scons.py is in your path already

    Edit: OK, so you'll have to do something like C:\Python27\python.exe scons.py
    Edit2: You did install python 2 and not 3, right? Also python 2 needs to be in your path, not python3. Unless you do C:\Python27\python.exe C:\Python27\whatever\whatever\scons.py

     I skipped the Python installation section, since I already had Python (3), maybe you should put a warn in the Wiki, so that anyone who already has Python, will still read that there is the need to use Python 2. I will install Python 2 now.

     

    EDIT: Is there a way I can add "C:\Python27\" but keeping "python" var for Python3 and make "python2" var for Python2? Anyway, I'll just replace the dirs in "Path" for now.

     

    EDIT 2: I have to reinstall SCons since I made it pointing to the Python3 directories.

     

    EDIT 3: I guess this is good: "$ scons.py

    scons: *** No SConstruct file found.
    File "C:\Python27\Lib\site-packages\scons-2.5.1\SCons\Script\Main.py", line 912, in _main"

    Make sure you are in the right directory when you run "scons.py". Be in the root directory of the source, the one with SConstruct in it.

    Also what I do is just not add python 2 to path at all, I always give a full manual path, like C:\Python27\python.exe C:\Python27\whatever\whatever\scons.py . That way I can keep python 3 as default, scons it the only thing that still uses python 2

    It says C compiler works, so it works even without cc.exe

    It gives a problem at the end tho :/

    That seems to be another MinGW bug (MinGW has so many bugs all the time, because windows development is kind of awful)

    I found this here: https://github.com/Alexpux/MSYS2-packages/issues/235

    Some kind of fix is here but I would have to look into how to apply it to the SConscript: https://github.com/Alexpux/MSYS2-packages/pull/239/files
