Description

Builds are failing in linux, likely due to an incompatibility issue with Vulkan 1.4:

CMake Error at /home/testing/.local/lib/vulkan/1.4.321.1/x86_64/share/llvm/cmake/LLVMExports.cmake:302 (message):
  The imported target "LLVMDxilHash" references the file

     "/home/testing/.local/lib/vulkan/1.4.321.1/x86_64/lib/libLLVMDxilHash.a"

  but this file does not exist.  Possible reasons include:

Vulkan 1.4 is compiling fine here.

The error sounds like problematic Vulkan libraries that you have installed your .local/lib directory.

Thanks Billiard. /home/testing/.local/lib/vulkan/1.4.321.1/x86_64/lib/libLLVMDxilHash.a is indeed missing as reported above.

So how could this happen, since I'm using the latest official vulkan-sdk (1.4.321.1) tarball, with all of its files installed to the above .local/lib path?

I wonder if it's an issue with the vulkan-sdk itself. Which minor version of vulkan 1.4 are you using? Can you check to see if it includes the above file?

I don't know anything about putting libraries in .local/lib.

I haven't manually installed any Vulkan SDK. I'm just building with the Vulkan-Headers 1.4.307 within Dolphin's Externals directory.

Anyways, this doesn't sound like a Dolphin issue to me.

I had forgotten vulkan-sdk isn't required for Dolphin as it is for other projects. It seems the Dolphin build process will attempt to use it if it detects it, and fails with newer versions (this didn't happen here on the test system with vulkan-sdk 1.3).

CMakeLists exposes the USE_SYSTEM_LIBS option to either use or ignore system libs entirely, though I tried that and got the same result. Is there another way?

Further testing revealed that this issue is specific to gcc, as Dolphin builds with llvm/clang. Build guidance as documented here should be updated to reflect deprecation of gcc if the issue can't be resolved.

  • Operating system Linux added
  • Operating system deleted (N/A)

Dolphin builds with both gcc and clang here, but I don't know what is causing your issue or how to solve it.

Thanks. I'm not sure why either although in fairness, this test system is a pretty standard environment. Can you compare your environment to this one as noted above (gcc version, etc?) Also you might try installing the vulkan-sdk, add the libraries to your .profile and see if it still builds with gcc, as that seems the source of the issue and is fairly common.

I'm on Arch Linux, gcc (GCC) 15.2.1 20251112.

I don't know anything about putting libraries in .profile.
I'm really not the correct person to be fixing dependency issues.

Interesting, I wonder if it's specific to gcc-14. gcc-15 isn't on the ubuntu repo yet.

Hopefully someone who works on the deps will see this and add input.

Also happens when building with clang 20.1.8 and vulkan-sdk 1.4.328.1. It tries to libLLVMDxilHash.a which isn't packaged in the most recent versions of the sdk, and it even throws this error after turning ENABLE_VULKAN off. I managed to make the error stop by commenting out everything related to setting the vulkan-sdk related environment variables and reloading the terminal.
