Check what version of gcc your build is using

[qiuxin]

Do me a favor to let me know whether gcc version is right.
[root@VM_16_11_centos ~]# gcc -v
Using built-in specs.

[qiuxin]

As far as my understanding, gcc version 4.8.5 support C++11 .

[qiuxin]

BTW, if I use yum command to install the following two packages, I do NOT need to download the source code and compile it. Right?
https://centos.pkgs.org/7/okey-x86_64/gtest-1.8.0-3.el7.x86_64.rpm.html
https://centos.pkgs.org/7/okey-x86_64/gtest-devel-1.8.0-3.el7.x86_64.rpm.html

[qiuxin]

solved. The mistake I made was:
1） I created a build folder in the googletest/googletest directory.

The right operation should be:
1) Create a build folder in googletest directory(NOT googletest/googletest directory.).
then:
cd build
cmake .. -DBUILD_GTEST=ON -DBUILD_SHARED_LIBS=ON
make
sudo make install

Everything goes well!
