Bug 483376 – =x11-base/xorg-server-1.14.209 - Compiling with clang needs patch.

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Stefan de Konink 2013-09-02 12:01:14 UTC]

To compile xorg-x11 with clang a trivial patch is needed to rename de define GCCUSESGAS to _GNUC_, it has been tested by the BSD community.

Reproducible: Always

What is the upstream status of this patch?

http://cgit.freedesktop.org/xorg/xserver/tree/hw/xfree86/common/compiler.h#n1355

Not incorporated.

[Comment 3 Stefan de Konink 2013-09-02 22:28:46 UTC]

Although the build is successful, I am unable to start X due to an undefined reference to vgaHWFreeHWRec for the intel driver. Which may or may not be related to the following;

Want to confirm that building with gcc instantly works. So next to the patch, something else is needed to get the working modules. Possibly related to -fPIC.

xorg-server-1.16.3-r1 builds fine with clang-3.5.0 and works as expected.
Upstream has already incorporated the needed patches to make it build with clang.
Please see also bug 427808, which was a similar report with an older version of xorg-server.
I think this can be safely closed since this version does exist in tree anymore, and later versions should not pose any problems.

Marking as fixed per comment 5.
