Wlroots, fatal error : xdg-shell-protocol.h: No such file or directory

Hi i was building a wayland compositor based on wlroots. When i was trying to add "wlr/types/wlr_xdg_shell.h" it produces an error showing :

/usr/local/include/wlr/types/wlr_xdg_shell.h:14:10: fatal error: xdg-shell-protocol.h: No such file or directory

is this a bug? i have tried modifying my meson.build file in protocols and projects folder. but nothing is changing.

here is the complete log:

Solution

The same problem happened to me once, please make sure that the wayland-protocols dependency name in your meson.build is same in the meson.build in the protocols folder

Eg: if you have defined your dependency like this:

meson.build in src directory (or your source directory)

deps=[
     server_protocols, // use this name in meson.build in protocols
     wayland_server,
     wlroots
]

Like this :

meson.build file in protocols directory

wl_protocol_dir=server_protos.get_pkgconfig_variable('pkgdatadir')

This works for me
