Errors about "Too many open files"?

I use my OSX(10.14.1) to build the code(v1.8.0).Everything is fine until I installed gcc@5 with “$ brew install gcc@5”.The building encounters errors.The problem still exits even after that I removed the gcc@5.Is the issue related to the gcc?How to fix the it?Thank you!

You don’t have encfs like this one?
