--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- It should not be hard to understand. You are using this path: /Volumes/External_7/_Ze-Bins/_GNU-Compilers/_13,1.x/ There is a comma in _13,1.x Just like you were using _12,1,x earlier. Stop doing that. Change it to _13.1.x and _12.1.x and please stop reporting bugs about this.
