Try to upgrade gcc

Centos7 gcc version default 4.8.3, Red Hat in order to stabilize and support the software version, the version is 4.8.3 yum, yum can not be used for software updates, so use scl. Remember networking.

yum install centos-release-scl scl-utils-build

yum list all --enablerepo='centos-sclo-rh'

 Comrades, our predecessors said is right, do not lift the GCC, as well as bigger pit. / Configure unsuccessful reason is the file you want to delete all before, I also thought suddenly shot forehead, then delete all the files re-extract, then ./configure, then make && make install

Finally OK.
