There is a scripts/recordmcount.pl file under the linux source folder, so I created a symbolic link to it: [13:34:48]ofayans@localhost:~/Realtek/rtl8188eu]$ cd /usr/src/kernels/linux-4.0.8/scripts/ [13:35:01]ofayans@localhost:/usr/src/kernels/linux-4.0.8/scripts]$ ls -s recordmcount.pl recordmcount

And tried again, but the build failed anyway:

Have you installed the kernel headers? These kinds of errors usually mean that the answer is "no".

As a final check, does the command "ls /lib/modules/uname -r/build" show a directory named "include"? Those ` characters are the back tick, usually found next to the number 1.

I have kernel headers installed. However, /lib/modules/4.0.7-300.fc22.x86_64/build initially was a symlink pointing to a nonexistent folder /usr/src/kernels/4.0.7-300.fc22.x86_64 I tried two things that did not help:

1. Removed this symlink and created a new one pointing to /usr/include/linux (a folder belonging to kernel-headers package), then tried to build and failed: make[1]: *\ No rule to make target 'modules'. Stop.
2. downloaded a vanilla kernel of the same version as my running kernel, unpacked it to /usr/src/kernels, created a 'build' symlink to it in /lib/modules/4.0.7-300.fc22.x86_64/ folder, then in the kernel source tree issued make oldconfig && make modules_prepare Then tried to build again which resulted in the error I described in initial message

Are you downloading the zip file? That is the worst way to do it. Use the "git clone" to get the source. That way, you only need to "git pull" to get any updates, and you can switch branches. In fact, the v4.1.8_9499 branch is better than master. Try that and see if the error persists.

It seems as if your headers are properly installed. I have no idea where those error messages are coming from. I do not have any experience with F22. What version of gcc is being used?
