Hi. I am trying to compile ReactOS on my macbook with OSX 10.10 on it, but I got an error. Building tools compiled quite well (with some warmings, but I think that it is ok), but when I call "ninja all» I got error:
bash-3.2$ cd ../../output-MinGW-i386/reactos
bash-3.2$ ninja

and so on
What I am doing wrong? I have googled, but I don’t found anything relevant

Thanks
