Why do I get "error: implicit declaration of function" when performing "make" on vmwgfx

Question

我非常接近在 Fedora 23 64 位（使用最新的 Rawhide 内核）上编译 VMWare guest GL driver，但我在 "make":

期间遇到错误

$ cd $TOP/vmwgfx
$ make

make -C /lib/modules/4.4.0-0.rc2.git2.2.fc24.x86_64/source  SUBDIRS=`/bin/pwd` DRMSRCDIR=`/bin/pwd` modules

我对 Makefile 及其语法不是很熟悉。这里可能发生了什么？

解决这个问题的方法是安装 4.3 内核，而不是 4.4 内核。
