Description

As of commit c51c044142fd0c91839ddc242d9da6efcbb4a526, Dolphin does not compile with gcc-8. Attempts to compile yield the following:

/usr/lib/gcc/x86_64-linux-gnu/8/include/immintrin.h:113:10: fatal error: movdirintrin.h: No such file or directory

Note that gcc-7 compiles fine. Tested on Linux kernel 4.15, x64.

The bisect is total nonsense: https://github.com/dolphin-emu/dolphin/commit/c51c044142fd0c91839ddc242d9da6efcbb4a526
This commit does not touch any code, it only updates the translation files.

The error message you provide gives me the impression that there's something wrong with your GCC 8 installation.
Also: GCC 8 has not been released yet (See https://gcc.gnu.org/).

Could you provide the exact version of the compilers you were using to test this (gcc-7 --version and gcc-8 --version, respectively)?

Also please attach a full build log.

They technically never said it was the version where the issue started :)

That was not from a bisect, it was just to show that the most recent commit as of this writing does not compile against gcc-8. I didn't bisect because I assumed no part of master has supported gcc-8 (though in fairness, past updates to gcc have always been fully backwards compatible and I've never had issues of this sort before).

There doesn't seem to be anything wrong with my gcc installation, I've been following the same update path as with prior updates and other projects seem to compile fine with gcc-8.

GCC-8 was just released to the Ubuntu repo: https://launchpad.net/ubuntu/+source/gcc-8

Versions:

Compiles: gcc-7.3.0
Does not compile: gcc-8.0.1

The version of gcc-8 shipped with Ubuntu 18.04 is indeed bust and missing that header. If you use 8.1.0 currently in Cosmic, then it should get further but you will probably run into the errors in issue 11047.
