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

Issue

I'm very close to have compiled the VMWare guest GL driver on Fedora 23 64-bit (using latest Rawhide kernel), but I'm getting errors during "make":

$ 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
make[1]: Entering directory '/usr/src/kernels/4.4.0-0.rc2.git2.2.fc24.x86_64'

I'm not very familiar with Makefile and its syntax. What could be going on here?


Solution

The solution to this was to install the 4.3 kernel, not the 4.4 kernel.
