I get: echo | g++ -v -E -x c++ - 2>&1 | sed -n '/#include <...> search starts/,/End of search list/p' #include <...> search starts here: /usr/lib/gcc/x86_64-redhat-linux/4.6.3/../../../../include/c++/4.6.3 /usr/lib/gcc/x86_64-redhat-linux/4.6.3/../../../../include/c++/4.6.3/x86_64-redhat-linux /usr/lib/gcc/x86_64-redhat-linux/4.6.3/../../../../include/c++/4.6.3/backward /usr/lib/gcc/x86_64-redhat-linux/4.6.3/include /usr/local/include /usr/include End of search list. And: readlink -f /usr/lib/gcc/x86_64-redhat-linux/4.6.3/../../../../include/c++/4.6.3 /usr/include/c++/4.6.3 The g++-v3 path was correct for GCC 3.0 and 3.1 but not since then, see http://gcc.gnu.org/onlinedocs/libstdc++/faq.html#faq.v2_headers
