Cannot find "gomp" on Windows 10

I am using Windows 10 and MATLAB 2017a, the compiler message is:

I don't know what is happening. The message says "MEX completed successfully", but then it reports tons of errors. So what is "spam"? What is "gomp"? Are they needed on Windows 10 to use ihog? Can I ignore them? Do I have to install cygwin to compile on Windows+Matlab?

I changed compiler='vs'; and it compiles successfully. Please disregard my post. Thanks.
