Good catch! I thought it'd be done automatically for all dependencies included in common_ss (system_ss is included in common_ss and lists fdt as a dependency), but actually it needs a small tweak: diff --git a/meson.build b/meson.build index 24502f4ff6a..342df23269d 100644 --- a/meson.build +++ b/meson.build @@ -3898,7 +3898,7 @@ foreach target : target_dirs target_common = common_ss.apply(config_target, strict: false) objects = common_all.extract_objects(target_common.sources()) - deps = target_common.dependencies() + arch_deps += target_common.dependencies() target_specific = specific_ss.apply(config_target, strict: false) arch_srcs += target_specific.sources() @@ -3954,7 +3954,7 @@ foreach target : target_dirs emulator = executable(exe_name, exe['sources'], install: true, c_args: c_args, - dependencies: arch_deps + deps + exe['dependencies'], + dependencies: arch_deps + exe['dependencies'], objects: lib.extract_all_objects(recursive: true), link_depends: [block_syms, qemu_syms], link_args: link_args, I'll include it in a v2 once I test it more fully.

Now that boards are enabled by default and the "CONFIG_FOO=y" entries are gone from configs/devices/, there cannot be any more a conflicts between the default contents of configs/devices/ and a failed "depends on" clause. With this change, each individual board or target can express whether it needs FDT. It can also include it in the build via "select DEVICE_TREE", instead of having each hw/*/meson.build file do it by hand, and this will bring in more components such as CONFIG_GUEST_LOADER. This allows building non-microvm x86 emulators without having libfdt available.
