I tried to run sway on nvidia drivers with WLR_RENDERER=vulkan, but it didn't work. So I ran it with VK_LOADER_DEBUG=all, which printed the following lines: (I will attach the whole log) - /usr/lib64/libVkLayer_utils.so: undefined symbol: custom_stype_info - Requested layer "VK_LAYER_KHRONOS_validation" failed to load! However, media-libs/vulkan-layers are built with X and wayland USE flags. I ran 'nm /usr/lib64/libVkLayer_utils.so' and 'nm /usr/lib64/libVkLayer_khronos_validation.so', and it showed that they haven't got any symbols: - nm: /usr/lib64/libVkLayer_khronos_validation.so: no symbols - nm: /usr/lib64/libVkLayer_utils.so: no symbols They're valid, as file says: - /usr/lib64/libVkLayer_utils.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped - /usr/lib64/libVkLayer_khronos_validation.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped 'vkcube --validate' fails too, with the same error. But just 'vkcube' runs fine. Reproducible: Always Steps to Reproduce: 1. Install proprietary nvidia drivers 2. Install media-libs/vulkan-layers-1.3.239 3. Try to run 'vkcube --validate' Actual Results: /usr/lib64/libVkLayer_utils.so: undefined symbol: custom_stype_info Expected Results: I expected it to work.

vkcube --validate seems to work fine with stable vulkan-layers-1.3.236-r1, but not with 239 where I get the same stype thing (I'm on nvidia too, not that nvidia would have any relation with what the libraries contain, it's not used when building). I'd guess may be related to the shared build that got changed around in 239, sarnex may know better. Interestingly 239 gives me a 3MB utils.so (stripped), and 236 is only 102kB? (you'd think it'd be the other way around if something is missing). That aside, nm reporting "no symbols" is normal because you haven't used -D (dynamic, for shared libs). Haven't tried sway, wouldn't use it as a reference for issues with nvidia (it works when the stars align at best). But you could try to downgrade the stable 1.3.236 vulkan stack to see if it's really this (annoyingly need to downgrade the entire stack to 1.3.236, glslang, vulkan-layers, vulkan-headers, etc... or portage will complaint)

I'll rename the bug, because it's confusing. Also, thanks for the tip with nm, didn't know that.

(In reply to Nikita Romanyuk from comment #6) > I thought it was due to nvidia because I recently used amdgpu and everything > worked fine. How long ago is recently? 1.3.239 was added on Feb 4 2023, so if before then you were probably using 1.3.236 with amdgpu.

Then, I was using 236, yes.
Same problem here. I'm doing vulkan development and I can't load the validation layer after the update: ERROR [GENERAL]: /usr/lib64/libVkLayer_utils.so: undefined symbol: custom_stype_info ERROR [GENERAL]: Requested layer "VK_LAYER_KHRONOS_validation" failed to load! Error: VulkanMsg("Failed to create instance", ERROR_LAYER_NOT_PRESENT) it's broken on vulkan-layers-1.3.239, but it works with version 1.3.236-r1 (had to downgrade my entire vulkan stack for that) Running mesa 22.3.6 on a 6700 XT
Sorry for the late response, I can reproduce this on my local system, I'll try to figure it out today.
Ok, I have something that fixes vkcube --validate but I don't know if it's totally correct, can someone who has more experience with vulkan layers test the attached patch in other vulkan layers use cases and make sure you don't get compile time linker errors or runtime ld errors? You need to use user patches (https://wiki.gentoo.org/wiki//etc/portage/patches#Example) as it relies on another patch being applied before this. Root cause, as usual, is upstream is a mess. Thanks

No replies, so I guess we'll hear from someone if it breaks something
Validation layers maintainer replied to a Github issue, saying that we patched it wrong. https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/5289 He also provided an explanation why that happens: libVkLayer_utils is not supported being built as a .so, and hasn't been supported for a long time. https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/5519#issuecomment-1485518954 I'll send a Github pull request, fixing this issue and reverting the old fix.
