我不太确定如何提出问题或在哪里寻找答案。任何信息都会有所帮助。

Answer 1

您正在使用仅支持OpenCL 1.1的台面。如图in the source code所示，它尝试使用-cl-fp32-correctly-rounded-divide-sqrt选项构建OpenCL内核，该选项已添加到OpenCL 1.2中，解释了该错误。您应该可以通过删除该特定选项来解决此问题，但是删除该选项可能会导致副作用。

从侧面说，台面OpenCL的实现还不及标准。您确实应该使用AMDGPU-PRO（专有，还包括OpenGL和Vulkan驱动程序-从AMD的站点下载）或ROCm（具有专有组件的开源软件，比AMDGPU-PRO更新，但硬件/软件支持更有限），它不仅支持新的OpenCL功能（分别为1.2和2.0+版本），而且还提供了明显更好的性能。
