Wolfram says that the solution involves the Hypergeometric Function.

So I have been having trouble with finding the indefinite integral of
1/ (1+x^4)^(1/4), by this I mean (1+x^4)^(-1/4).
I was given a hint that says to use the substitution t^4= 1+x^(-1/4).
Any help would be appreciated, and thanks in advance!
