When compile llvm 3.1, why get error: expected primary-expression before ‘>’ token

For some reason, I need to install llvm 3.1 or llvm 3.0, but I'm getting this error when during make.

I guess there might be a compatibility issue between llvm 3.0 and gcc 7.0.0, so I installed gcc-4.6.3, and use this cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/home/ubuntu/install -DCMAKE_CXX_LINK_FLAGS="-Wl,-rpath,$HOME/gcc463/install -L$HOME/gcc463/install" -G "Unix Makefiles" ../llvm to configure. But the same error still occurs. Anybody knows why and how to fix it? Thanks!!
