g++コンパイラによるエラーの解決方法がわからない。

下記のコードですが下部のg++コンパイラによるエラーコードですがどうやって修正すればいいのでしょうか？色々触ってみましたが解決方法がわかりません。文字数の関係でだいぶ省略しています。

原文「　/usr/include/GL/glu.h:68:78: error: expected ‘)’ before ‘*’ token
68 | void APIENTRY gluQuadricCallback(GLUquadric *qobj,GLenum which,void (CALLBACK *fn)());　」

日本語翻訳「　/usr/include/GL/glu.h:68:78：エラー：「*」トークンの前に「）」が必要です
68 | void APIENTRY gluQuadricCallback（GLUquadric * qobj、GLenum which、void（CALLBACK * fn）（））;　」
