are you still using gcc-8? Here this one didn't work at all for me,
compiling always aborted early with compiler errors. It worked
immediately though after I removed ggc-8 and upgraded gcc-7 to v. 7.3
from sid.

In my case after I took you helpful advice and installed libelf-dev in GCC 8 (which I am still using) the crash I had went away.........

I think now GCC 8 is close to working OK.

Perhaps it needs another little nudge or some other package we don't know about.

I have sent the gnu gcc help people the following email:

Dear All,

I am running debian unstable on an amd64 kaveri box.

I recently installed GCC 8 from the Debian experimental site:

https://packages.debian.org/experimental/devel/gcc-8

I also installed libelf-dev.

It did run correctly without it.

I have been using it to try to compile and install linux kernel 4.14.15 using the

debian package make-kpkg.

The output from doing this is here:

https://pastebin.com/sgrhdCKW

I copied over the config file from/boot and ran make-clean and the command: yes "" | make oldconfig before running make-kpkg.

Kernel compilations I do in gentoo usually take a while.

This ran too quickly I think.

Something is not quite right here.

Perhaps some more depedent packages needed to be installed to make GCC8 run happily.

Do you have a test file I can compile that will check whether GCC 8 is really running correctly?

The discussions on these two threads are relevant:

https://lists.debian.org/debian-user/2018/01/msg01159.html

https://lists.debian.org/debian-user/2018/01/msg01002.html

We are all trying to compile kernels that defeat the meltdown and spectre vulnerabilities.

Comments appreciated.

Regards

MF
