From ebe3a53db1c0bb34e1ca963b95d1f222115f93f8 Mon Sep 17 00:00:00 2001 From: Daniel Stone Date: Fri, 7 Jul 2017 10:48:58 +0100 Subject: [PATCH] Add fallback definition for EGL_CAST The EGL API update from d11104f2b5 introduced a dependency on the EGL_CAST() macro, provided by an updated eglplatform.h. Given that we don't provide eglplatform.h, add a fallback definition for if we're building against Mesa 17.0.x or similar. https://bugs.gentoo.org/show_bug.cgi?id=623926 --- src/gen_dispatch.py | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/src/gen_dispatch.py b/src/gen_dispatch.py index 306a83b..c22fd82 100644 --- a/src/gen_dispatch.py +++ b/src/gen_dispatch.py @@ -491,6 +491,15 @@ class Generator(object): self.outln('#include "epoxy/gl.h"') if self.target == "egl": self.outln('#include "EGL/eglplatform.h"') + # Account for older eglplatform.h, which doesn't define + # the EGL_CAST macro. + self.outln('#ifndef EGL_CAST') + self.outln('#if defined(__cplusplus)') + self.outln('#define EGL_CAST(type, value) (static_cast(value))') + self.outln('#else') + self.outln('#define EGL_CAST(type, value) ((type) (value))') + self.outln('#endif') + self.outln('#endif') else: # Add some ridiculous inttypes.h redefinitions that are # from khrplatform.h and not included in the XML.
