GTK4 Win64 Cross Build and vulcan

[sechshelme]

I wanted to build GTK4 DLLs for Win64 on my Linux.
But it aborts with a Vulcan error message.
Is there any way to fix this?

cross.txt:

[binaries]
c = 'x86_64-w64-mingw32-gcc'
cpp = 'x86_64-w64-mingw32-g++'
ar = 'x86_64-w64-mingw32-ar'
strip = 'x86_64-w64-mingw32-strip'
exe_wrapper = 'wine64'
windres = 'x86_64-w64-mingw32-windres'

[host_machine]
system = 'windows'
cpu_family = 'x86_64'
cpu = 'x86_64'
endian = 'little'

Build:

meson ../gtk/ --cross-file=../cross.txt

Error:
../gtk/meson.build:624:13: ERROR: Dependency lookup for vulkan with method 'pkgconfig' failed: Pkg-config binary for machine 1 not found. Giving up.

Hi,

Looks like you don’t have the vulkan headers for mingw32…

Have you tried passing -Dvulkan=disabled to meson?

Not sure if vulkan is fully supported by gtk on Windows… The msys2 build currently disable it.
