Problem: In
ocl_kernel_builder,cl::Program::buildonly raisescl::BuildErrorforCL_BUILD_PROGRAM_FAILURE, and only that branch prints the OpenCL program build log. Other build-time failures — notablyCL_OUT_OF_RESOURCES, raised when a generated kernel exceeds device limits (e.g. SLM/local memory on integrated GPUs) — propagate as a plaincl::Error, whose handler rethrows with just the error code and no build log. This leaves such kernel-build failures effectively undiagnosable without local source patching.Solution: In the
catch (const cl::Error&)branch ofocl_kernel_builder::build(src/plugins/intel_gpu/src/runtime/ocl/ocl_kernel_builder.hpp), fetch and log the program build log viaprogram.getBuildInfo<CL_PROGRAM_BUILD_LOG>()before rethrowing, mirroring the existingcl::BuildErrorbranch and using the sameGPU_DEBUG_INFOchannel. The log retrieval is wrapped so a secondary failure does not mask the original error. No behavior change in the success path; output is only produced under GPU verbose logging.
