Looks like you are trying to build in /usr/src/linux-headers-4.15.0-88 This doesn't contain any source files. Go down into directorties below selftest or /usr/src/linux-headers-4.15.0-88/kernel you will see that there are no .[ch] files in these directories. You have to install Ubuntu 16.04lts source package for kernel or checkout kernel git repos to build kernel and selftests for that kernel from sources. thanks, -- Shuah
