Drop qxl object from softmmu source set, it is built as module.
Also drop CONFIG_QXL condition from qxl_ss.add. First because it is
pointless, the whole thing is wrapped into "has_key('CONFIG_QXL')".
Second because it doesn't work for some reason. Looks like the source
files are not added to the set for some reason and we end up with an
empty hw-display-qxl.so.

Hi, > if config_all_devices.has_key('CONFIG_QXL') > qxl_ss = ss.source_set() > - qxl_ss.add(when: 'CONFIG_QXL', if_true: files('qxl.c', 'qxl-logger.c', 'qxl-render.c')) > + qxl_ss.add(files('qxl.c', 'qxl-logger.c', 'qxl-render.c')) > hw_display_modules += {'qxl': qxl_ss} > endif > > -softmmu_ss.add(when: 'CONFIG_QXL', if_true: files('qxl.c', 'qxl-logger.c', 'qxl-render.c')) Damn. Turned out to not be that easy. Modular builds work fine, but with non-modular builds I have the problem that qxl_ss is merged into softmmu_ss *unconditionally*. So when building two targets, one with qxl enabled (i386 for example) and one without pci support (avr for example) I get missing symbols for pci+vga due to the attempt to link qxl into avr-softmmu. Any hints how to solve that one? thanks, Gerd

You have found why it's got that "when:". :) > Any hints how to solve that one? I think this should be enough---fixing it in the common code, not with a qxl-specific change: diff --git a/meson.build b/meson.build index 6ed3c37f46..88f2254f3b 100644 --- a/meson.build +++ b/meson.build @@ -923,7 +923,7 @@ softmmu_mods = [] foreach d, list : modules foreach m, module_ss : list if enable_modules and targetos != 'windows' - module_ss = module_ss.apply(config_host, strict: false) + module_ss = module_ss.apply(config_all, strict: false) sl = static_library(d + '-' + m, [genh, module_ss.sources()], dependencies: [modulecommon, module_ss.dependencies()], pic: true) if d == 'block' :-O If you want to get rid of the "if config_all_devices.has_key(...)", you perhaps could try doing something like module_srcs = module_ss.sources() if module_srcs.length() == 0 continue endif sl = static_library(d + '-' + m, [genh, module_srcs], dependencies: [modulecommon, module_ss.dependencies()], pic: true) etc. This would work also for the CONFIG_VIRTIO_GPU changes.

That nicely explains why the "when:" didn't work in the first place. > etc. This would work also for the CONFIG_VIRTIO_GPU changes. Yes, virtio-gpu modules are next on the list ;) thanks, Gerd
