compilation - OpenCL 程序在使用 MinGW 编译时无法识别驱动程序，但在使用 Visual Studio 构建时正常运行

Question

我一直在研究一个 OpenCL 程序，该程序可以试用 Mersenne 数。当我使用 Microsoft Visual Studio 编译它时，它按预期工作。但是，尽管它也可以使用 MinGW（64 位）编译而没有错误，但该程序似乎无法与 OpenCL 驱动程序一起使用。

在初始化例程之后，程序应该打印有关所选设备的信息。但是，程序在启动后立即终止并且不打印任何错误。我在几台计算机上尝试了同样的事情，但它只在一台计算机上工作。任何人都知道可能导致此问题的原因是什么？

这是完整的存储库供参考：https ://github.com/Bdot42/mfakto

这是带有我修改的makefile：

# set x86_64 (64-bit) as default
BITS := x86_64
BITFLAG := -m64

# check whether to build 32-bit version
ifdef bitness
  ifeq ($(bitness), 32)
    BITS := x86
    BITFLAG := -m32
  endif
endif

# Check if static linking is requested
ifdef static
  ifeq ($(static), yes)
    STATIC := -static
  endif
endif

# some commands won't work on Windows
ifeq ($(OS), Windows_NT)
  CP = copy
  RM = del /f
else
  CP = cp
  RM = rm -f
endif
