Supposing "compound" means "conjoined", use the same case for the two pronouns that are conjoined. "He and I" might be okay, with both forms subjective, or "him and me" might be okay, with both forms objective. But "he and me" or "him and I", with one subjective and one objective form, will probably count as mistaken in every variety of English.
In informal colloquial English, conjoined pronouns are always objective. In formal or archaic English, the pronouns are the same as would be used for a simple, unconjoined pronoun.
