Re: [Xen-users] Compiling Xen with gcc 7

[Mark Pryor <tlviewer@xxxxxxxxx>]

I don't support Slackware, but for anyone that needs a Debian-delta or SRPM/SPEC combo, I support xen builds of 4.8.x/4.9.0 on Fedora 25/26, Centos7, Ubuntu, and Debian.

Fedora 26 defaults to gcc-7 and I've build Debian Buster with it too.

These have full build-requires and install depends.

Hi folks,

I replaced an ancient setup of Slackware 14.1 with Xen (4.3.1) on kernel

3.12, with glibc 2.24, with the fresh components of everything

(Slackware 14.2 current, kernel 4.9.40, glibc 2.26, gcc 7.1.0, xen

4.8.1). I had quite a bit of trouble compiling Xen with gcc 7.1.0, though.

gcc 7 issues a lot more warnings than previous versions, and in many

places the gcc flag -Werror effectively halts the make, as warnings are

treated as errors.

As I really needed to get the stuff working, I changed the the -Werror

to -Wno-error where ever possible. I know it's stupid, but I had only

hours to get it going. The server is working, there seems to be no real

problems, but I want to do it the proper way.

Is there anybody out there who's built xen 4.8.1, or 4.9.0 with gcc 7?

And if so, where should I tweak the flags, or patch the source?

Best regards,

Peter
