All spaces at the beginning of a line. These should be tabs. Or Make will make a really obscure mistake. Make sure these are tabs and try again.
See the button on the left side of the keyboard labeled “tab.” Delete the spaces and press once to insert a tab character.
Give it a try make all. IIRC (several years have passed since I had to dump files with make files), most of them will be by default all, but maybe your not.
