Failed to get adapter info: wgpu: failed to get adapter info

[anyanfei]

my system:window
go version : go version go1.25.0 windows/amd64
add dll in my project: wgpu_native.dll

run adapter example , error : Failed to get adapter info: wgpu: failed to get adapter info

May I ask why such a situation occurs?

Thanks for reporting! Let's diagnose this.

Required wgpu-native version: v24.0.3.1 (get it from wgpu-native releases)

Please check:

1. Which version of wgpu_native.dll are you using?

   • Download wgpu-windows-x86_64-release.zip from the link above
   • Extract wgpu_native.dll to your project directory

2. Where is the DLL located?

   • It should be in the same directory as your executable, or in PATH

3. Can you try the simpler triangle example first?

   go run ./examples/triangle

4. What GPU do you have? (run dxdiag and check Display tab)

5. Try adding debug output:

   adapter, err := instance.RequestAdapter(nil) // try with nil options first
   if err != nil {
       log.Fatalf("Failed to request adapter: %v", err)
   }
   fmt.Printf("Adapter handle: %#x\n", adapter.Handle())

The error means wgpuAdapterGetInfo returned non-success status. This usually indicates:

• DLL version mismatch (most common)
• GPU driver issues
• Adapter not properly initialized

Let me know the results!

yes , it work's good:

go run .\main.go

Adapter: 0x2d3eaf99a90

And the triangle when i change the code on 49 lines with:
kernel32 = windows.NewLazyDLL("kernel32.dll")
procGetModuleHandleW = kernel32.NewProc("GetModuleHandleW")

when i run , it works good , show the window and a triangular graphic element . But can not run adapter_info yet.

Great progress! So the adapter is working and triangle renders correctly.
The issue is specifically with wgpuAdapterGetInfo returning non-success status.

Can you try this debug test to see if other adapter APIs work?

package main

import (
    "fmt"
    "github.com/go-webgpu/webgpu/wgpu"
)

func main() {
    instance, _ := wgpu.CreateInstance(nil)
    defer instance.Release()
    
    adapter, _ := instance.RequestAdapter(nil)
    defer adapter.Release()
    
    fmt.Printf("Adapter handle: %#x\n", adapter.Handle())
    
    // Try GetLimits first (different API call)
    limits, err := adapter.GetLimits()
    if err != nil {
        fmt.Printf("GetLimits failed: %v\n", err)
    } else {
        fmt.Printf("GetLimits OK: MaxTexture2D = %d\n", limits.Limits.MaxTextureDimension2D)
    }
    
    // Then GetInfo
    info, err := adapter.GetInfo()
    if err != nil {
        fmt.Printf("GetInfo failed: %v\n", err)
    } else {
        fmt.Printf("GetInfo OK: %s\n", info.Device)
    }
}

This will help identify if the issue is specific to GetInfo or affects other adapter APIs too.
