我试图编译CUDA样本。如果我cd到示例，然后运行make，它会给我一个错误：
macair93278:samples r8t$ cd 0_Simple/UnifiedMemoryStreams/
macair93278:UnifiedMemoryStreams r8t$ ls
Makefile Makefile-e NsightEclipse.xml UnifiedMemoryStreams.cu readme.txt
macair93278:UnifiedMemoryStreams r8t$ make
有几个警告，然后
clang: warning: argument unused during compilation: '-fopenmp'
ld: library not found for -lgomp
clang: error: linker command failed with exit code 1 (use -v to see invocation)
-----------------------------------------------------------------------------------------------
WARNING - OpenMP is unable to compile
-----------------------------------------------------------------------------------------------
This CUDA Sample cannot be built if the OpenMP compiler is not set up correctly.
This will be a dry-run of the Makefile.
For more information on how to set up your environment to build and run this sample, please refer the CUDA Samples documentation and release notes
感谢您的帮助。
