Fix build errors for wgpu backend by lucascompython · Pull Request #9377 · ocornut/imgui

lucascompython · 2026-04-23T16:32:51Z

I didn't check, but I'm pretty sure wgpu-native updated their wgpu-headers so they now better match dawn and wgvk.
Some of the conditional compilation statements that are needed to support the multiple backends (wgpu, dawn and wgvk) are no longer needed for WGPUProgrammableStageDescriptor, which became WGPUComputeState on all backends, same for the vertex input configuration and WGPUSurfaceGetCurrentTextureStatus_OutOfMemory which became WGPUSurfaceGetCurrentTextureStatus_Error.

Tested in my own small imgui, SDL3 and wgpu app, both dawn and wgpu-native.

This PR fixes the following compilation errors:

Reference commit gfx-rs/wgpu-native@f16f716

Thank you!

It baffles me that those library don't have version numbers that may be checked with compile-time #if statements.

How about the other things which diverged in the backend?

do the example_glfw_wgpu/main.cpp, example_sdl2_wgpu/main.cpp, example_sdl3_wgpu/main.cpp need change to compile?
can ImGui_ImplWGPU_GetDeviceLostReasonName() and ImGui_ImplWGPU_GetErrorTypeName() be enabled?
should ImGui_ImplWGPU_GetLogLevelName() be disabled?
should ImGui_ImplWGPU_IsSurfaceStatusSubOptimal() be changed?

From my testing, with this PR I can build all of those examples without changing them, however, (and I don't know if im doing anything wrong) with both the v29 wgpu release and the latest commit from trunk, I cannot run any of these examples with wgpu.

I got the following errors:

example_sdl3_wgpu, which seems to not have wgpuInstanceWaitAny implemented:
