Windows Build FAILED

[acasta69]

@Acasta69, I'm starting to think that compilation problem on Azure is due to the use of a Linux OpenCL SDK on Windows. The error seems to suggest that and the compilation on Windows works fine here.
You should check the OpenCL headers, the definition of "cl_ulong" type should be like:

Code: Select all

typedef unsigned __int64        cl_ulong;

I think I'm using this OpenCL SDK: https://github.com/GPUOpen-LibrariesAnd ... K/releases

I was using the same SDK, but since I installed the CUDA SDK, NVIDIA OpenCL is found and used.
The definition in 'cl_platform.h' in both SDKs matches the one you posted above.

Compilation with OpenCL and with CUDA is ok, the problem is when OpenCL is disabled.
The cl headers are not loaded in that case, even if 'ocl.h' is included, so 'cl_ulong' is not defined.

Can it be that there's a typo in here:

Code: Select all

#if defined(SLG_OPENCL_KERNEL)
	unsigned long pixelsIndex;
#else
	cl_ulong pixelsIndex;	
#endif

Are we using an OpenCL type even if we are not in an OpenCL kernel (i.e. defined(SLG_OPENCL_KERNEL) is false)?

Ah, ok, it makes sense, I was thinking the error was when compiling the OpenCL enabled version. Indeed, cl_ulong is an OpenCL data type and it is not defined when OpenCL is not enabled.

I pushed a fix.

So where are caches stored, so I can clear/ delete all & make proper comparison?

For LuxCore 2.3 it should be:

Code: Select all

C:\Users\<username>\AppData\Local\Temp\kernel_cache

For v2.4 there are two locations:

Code: Select all

C:\Users\<username>\AppData\Local\Temp\cuda_kernel_cache
C:\Users\<username>\AppData\Local\Temp\ocl_kernel_cache

Compilation with OpenCL and with CUDA is ok, the problem is when OpenCL is disabled.

It is the same error than before: "An internal error has occurred in the compiler". Your compiler is broken (or you have an hardware problem).

The build on Azure is working fine: https://dev.azure.com/LuxCoreRender/Lux ... 34e5207e1b

OK. After restarting Windows "Build succeeded."
Indeed, something got corrupt on my side & now I at least know what to do, if it happens again, so: "Thank you for the note."
