I'm trying to build v8 in Linux, on a quite recent CentOS.

# cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)

# rpm -q gcc
gcc-4.8.5-4.el7.x86_64

# rpm -qa|grep stdc
libstdc++-4.8.5-4.el7.i686
libstdc++-devel-4.8.5-4.el7.i686
compat-libstdc++-33-3.2.3-72.el7.x86_64
libstdc++-4.8.5-4.el7.x86_64
libstdc++-devel-4.8.5-4.el7.x86_64
compat-libstdc++-33-3.2.3-72.el7.i686

The "make x64.debug" command runs for a while, compiling lots
of files, and then starts to fail with this. How can it not find libstdc++?

What have I missed?

You're querying gcc but your build is using clang. You can disable
clang by doing `make x64.debug GYPFLAGS=-Dclang=0`

Thank you Louis, now it compiles and links perfectly.
