OpenCL在调用clGetPlatformIDs时崩溃

我是OpenCL的新手。在运行Windows 7的具有Intel（R）HD Graphics 4000的Core i5计算机上工作，我安装了支持OpenCL的最新Intel驱动程序。GpuCapsViewer确认我具有OpenCL支持设置。我使用英特尔OpenCL SDK开发了一个简单的HelloWorld程序。我已经成功编译了程序，但是运行时，由于分段错误而调用clGetPlatformIDs（）时，它崩溃了。这是我的代码：

#include 
#include 

int main() {
    std::cout << "Test OCL  without driver" << std::endl;

    cl_int err;
    cl_uint num_platforms;

    err = clGetPlatformIDs(0, NULL, &num_platforms);
    if (err == CL_SUCCESS) {
        std::cout << "Success. Platforms available: " << num_platforms
                << std::endl;
    } else {
        std::cout << "Error. Platforms available: " << num_platforms
                << std::endl;
    }

    std::cout << "Test OCL without driver" << std::endl;
    std::cout << "Press button to exit." << std::endl;
    std::cin.get();
    return 0;
}

GpuCapsViewer如何成功确认OpenCL支持并可以使用它运行其演示，但我却无法运行我的代码？两者必须使用相同的功能，对吗？

已经为此工作了几天。甚至尝试重新安装驱动程序。有任何想法吗？

GpuCapsViewer说：

驱动程序：R295.93（r295_00-233）/ 10.18.10.3496（3-11-2014）
OPENGL：OpenGL 4.2（GeForce GT 630M / PCIe / SSE2具有290 ext。）
OPENCL：OpenCL 1.1，GeForce GT 630M计算单位：2 @ 950MHz
CUDA：GeForce GT 630M CC：2.1，多处理器：2 @ 950MHz
PHYSX：GPU PhysX（NVIDIA GeForce GT 630M）
MULTI-GPU：不支持多GPU（2个物理GPU）

更新：

编译行：

g++ -I"C:\Program Files (x86)\Intel\OpenCL SDK\4.4\include" -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"Test3.d" -MT"Test3.d" -o "Test3.o" "../Test3.cpp"
Finished building: ../Test3.cpp

链接器行：

g++ -L"C:\Program Files (x86)\Intel\OpenCL SDK\4.4\lib\x64" -o "TestOpenCL"  ./HelloWorld.o ./HelloWorld2.o ./Test3.o   -lOpenCL
Finished building target: TestOpenCL

更新3：

使用DependencyWalker（http://dependencywalker.com/）来替代dumpbin。它生成以下警告：

Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

警告似乎是指以下所有DLL，这些DLL都标有“错误打开文件。系统找不到指定的文件（2）”错误消息。

更新8：

根据@antiduh的回答，我一直在尝试直接针对Windows \ System32文件夹中存在的OpenCL.dll进行链接。我正在使用mingw64。我得到这个：

更新9：现在，我可以使用以下代码行手动编译，链接和运行示例代码。

g++ -I. s.cpp -L. -lOpenCL

我简化了一切，并且一切正常。这显然与Eclipse使用的compile和link命令有很大不同。知道eclipse使用哪个参数会引起问题吗？而且，为什么eclipse首先在两个单独的步骤中编译为目标文件，然后尝试链接它们？
