Subject: [PATCH] Drop wayland-client.h include
Upstream: not sent
References: https://build.opensuse.org/package/show/X11:Wayland/vulkan-loader comment from 2022-07-12
wayland-client may be located outside the default search paths of the compiler
toolchain. In other words, *any* user of wayland-client must use `pkg-config
wayland-client --cflags` for compilation, and, later, `pkg-config
wayland-client --libs` for linking.
A Vulkan program that defines -DVK_USE_PLATFORM_WAYLAND_KHR would, in
the general case, also call at least some Wayland functions. The
build scripts for that program would have to employ `pkg-config
wayland-client --cflags --libs` in any case, based simply on the use
of said Wayland functions.
Now, there is a corner case wherein the program defines
VK_USE_PLATFORM_*, but does not make use of Wayland functions
directly:
echo "#define VK_USE_PLATFORM_WAYLAND_KHR
#include <vulkan/vulkan.h>
int main() {return 0;}" | gcc -x c -
"Should `pkg-config` be required for this?"
One opinion is that the use of -DVK_USE_PLATFORM_WAYLAND_KHR is so
explicitly willful that `pkg-config` is required.
Another stance is that, since no Wayland header and no Wayland
functions were directly used by the program, the program itself
should not have to use `pkg-config`; responsibility to satisfy the
"#include <wayland-client.h>" in vulkan.h would then fall to
vulkan.pc, which would have to pull in wayland-client.pc. That on the
other hand would pull in wayland for everyone, which is bad.
Either way, I found the following option: Delete the include for
which you would need wayland's -I flags. This works because we can
just add forward declaration like "struct wl_display;" to
vulkan_wayland.h. But we don't even need that. C (and C++) seem to be
fine with undeclared names, e.g.
//no "struct T;"
struct S { struct T *t; }
void f(struct T *t) {}
so I guess it's the solution, for now.
Keep in mind that, as soon as a program uses Wayland functions (directly; not
indirectly through vulkan), it needs to #include <wayland-client.h> anyway on
its own, and then the pkg-config case from the first paragraph applies.
