clBuildProgram returns CL_BUILD_PROGRAM_FAILURE，但没有发生错误

Question

我的程序在我的机器上运行良好。用户遇到奇怪的错误，目前我不知道如何调试。

clBuildProgram returns -11 表示 CL_BUILD_PROGRAM_FAILURE.

用 CL_PROGRAM_BUILD_STATUS 调用 clGetProgramBuildInfo，它 returns CL_SUCCESS 并且构建状态为 CL_BUILD_SUCCESS。

用CL_PROGRAM_BUILD_LOG调用clGetProgramBuildInfo，它returns CL_SUCCESS 日志粘贴在下面：

正如构建日志所说，编译和链接已完成，没有任何错误。那么可能是什么问题？

设备是Intel(R) Core(TM) i3-3240 CPU @ 3.40GHz。

我解决了这个问题。 clBuildProgram参数不正确

// Before:
clBuildProgram(program, 0, 0, "-cl-single-precision-constant -cl-denorms-are-zero -cl-fast-relaxed-math", 0, 0)
// After:
clBuildProgram(program, 1, &device, "-cl-single-precision-constant -cl-denorms-are-zero -cl-fast-relaxed-math", 0, 0)

clBuildProgram returns CL_BUILD_PROGRAM_FAILURE，但没有发生错误

clBuildProgram returns CL_BUILD_PROGRAM_FAILURE, but no error occured
