Access Violation When Loading Tahoe64.dll or Northstar64.dll in Tutorial Sample

[JindrichNikodem]

Hello frinds,

I'm trying to run the tutorial sample 64_mesh_obj_demo from the Radeon ProRender SDK. When attempting to load the plugin Tahoe64.dll or Northstar64.dll, I encounter a crash during context creation.

Specifically, the call to:

cpp
rpr_int tahoePluginID = rprRegisterPlugin(RPR_PLUGIN_FILE_NAME);
returns 0, which seems suspicious. Then, when I call:

cpp
CHECK(rprCreateContext(RPR_API_VERSION, plugins, pluginCount, settings.creationFlags, g_contextProperties, NULL, &outContext.context));
I get the following exception:

Kód
Unhandled exception at 0x0000000000000000 in 64_mesh_obj_demo64D.exe: 
0xC0000005: Access violation executing location 0x0000000000000000.

Environment:

OS: Windows 11 x64

IDE: Visual Studio 2022

SDK: Radeon ProRender SDK (latest from GitHub)

Sample: 64_mesh_obj_demo

Plugins tested: Tahoe64.dll, Northstar64.dll

CPU: Intel Core I7
GPU: NVIDIA 3050
HIP SDK: 25.Q3

What I've tried:

Verified that the DLLs are present in the bin directory

Rebuilt the SDK and samples from source

Installed HIP SDK

Attempted both Tahoe and Northstar plugins

Debugged the sample — crash occurs at rprCreateContext

Question:

Is there a required initialization step for the plugin before calling rprCreateContext? Is the plugin ID supposed to be non-zero? Or is the SDK intended only for static linking?

Any guidance would be greatly appreciated!
