Ok, my advice if you don't want to give up yet :-)
Don't try to force the use of gcc-8 until you know that everything runs
properly with the default compiler.
Maybe you should follow the advice from the previously posted error
message:
"make[2]: Entering directory '/usr/src/linux-4.14.15'
Makefile:942: *** "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y,
please install libelf-dev, libelf-devel or elfutils-libelf-devel". Stop."
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(Ignore the messages about the debian directory.)
If similar messages as the above appear again, try to figure out what
needs to be additionally installed (some *-dev packages might still be
missing).
Once you get past the first few minutes of the procedure when using the
default compiler and you see how one module after the other is compiled,
hit Ctrl-C, do "make mrproper" and start over again with gcc-8.
This is just my 2¢, but I believe "debugging" one thing at a time is the
more promising approach here.
Good luck (and for now good night :)
Michael
