I've been looking for a while on how to get DL running on Arch and I finally found it.

Arch's default compiler flags are:

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt"
CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt"

"-fno-plt" in C/CXXFLAGS and ",-z,now" in LDFLAGS need to be unset when compiling Mesa to get DL to not crash.

The other change required is to not use glvnd, with "-D glvnd=false". I tried building libglvnd with the same flags as Mesa, or none at all, but it didn't help.

The behavior is the same with Mesa 18.2.0 or Mesa-git, with LLVM 6.0 or master.
I haven't tried with autoconf though, only Meson, but I can try if you think it'd be helpful.

I've tried this on my 280X and another user's 580X, so I don't think it depends on the model. We're all on amdgpu.

I'd be happy to try / provide whatever would help.

Thank you!

Additional info:
* Current versions: Mesa 18.2.0, Linux 4.18.8, GCC 8.2.1, glibc 2.28, but it failed in previous ones too.
* I don't have any helpful log, as the game segfaults without these, a backtrace in gdb doesn't show me anything useful, and there's nothing in dmesg.
* I've reported that to upstream, but it was suggested to report it here instead, as Arch is applying non default FLAGS.

Steps to reproduce:
- Run Dying Light with standard Arch Mesa from Steam
- Get the game to segfault
This task depends upon

This is more of a GLEW bug that can be fixed in Mesa than in libglvnd I believe.
