我刚刚开始学习 OpenCL。我在输入make编译 HelloCL 程序时收到以下错误：
mkdir -p depends/x86_64
perl ../../../../../make/fastdep.pl -I. -I../../../../../include -I../../../../../samples/opencl/SDKUtil/include --obj-suffix='.o' --obj-prefix='build/debug/x86_64//' HelloCL.cpp > depends/x86_64/HelloCL.depend
mkdir -p build/debug/x86_64/

有人可以帮助我理解我所看到的错误，并提出需要进行的更正吗？
