Why compiling C++ in Mac always create *.dSYM directories? Is there a way to disable that?

It's because your Xcode project is set up to build debug symbols with an external dSYM file. This is actually very handy for release builds, as it means that you can strip debug symbols from your app, and when a user sends a crashdump to you, you can use the original dSYM file to generate a proper stacktrace for debugging.

Anyways, you don't need to disable debug symbol generation in your project. Instead, just change the debug symbol type to DWARF (instead of "DWARF with dSYM File"). You can also use Stabs, but that's the old format.

Edit: Ah, I see you meant from the command line, not from Xcode. I'm not sitting in front of my mac atm, but I see from the gcc4 manpage than you can specify -gstabs to use the Stabs format.
