Linker OpenCL未定义引用，但lib文件位于正确位置

我在为当前需要OpenCL的项目设置我的PC（Win 7 Ultimate 64 CPU AMD/GPU AMD）时遇到了一个奇怪的问题

我有MSYS，所以我正在与gcc合作开发mingw。我正在拼命地编译一个简单的工作，叫做openclexample

注意：包含“openclexample”的目录确实包含一个lib文件夹，包括重新实现的libOpenCL.a、OpenCL.lib和OVDecode64.lib

windows/system32中的OpenCL.dll

现在，当我尝试使用

$ gcc -std=c99 -lOpenCL -o openclexample.exe openclexample.c

我得到的只是OpenCL.def中列出的所有函数中的一堆未定义的引用错误

我已经阅读了数百个线程，但没有找到解决方案，一些人建议将其链接到-static，或者输入lib文件所在的路径。。。也不管用

如果有人有主意，我会非常感激的

链接器的参数必须顺序正确。您可以看到库搜索路径（-L）是正常的，因为链接器不会抱怨找不到库。符号未定义，因为在使用它的对象/源文件之前提到了-lOpenCL

$ gcc -std=c99 -o openclexample.exe openclexample.c -lOpenCL
