"The “dereferencing pointer to incomplete type” error commonly occurs in C when one tries to dereference a type (usually a struct) that is:
not declared at all.
declared, but not defined.
The error in the first bullet point occurs because C cannot find the struct that is being dereferenced. The reason for this could be that the struct may not have been declared, or that the user made a typographical error in the struct’s name"
from: https://www.educative.io/edpresso/resolving-the-dereferencing-pointer-to-inc...
At this stage, it seems to use generated xgcc to compile itself... a bit weird it get errors at this stage to me.
Will investigate a bit more later.
