Joan Touzet commented on COUCHDB-3432:
--------------------------------------

On my CentOS 7 machine, the output of the command "which c++" is "/bin/c++". 
That file is identical to /bin/g++ (checking the md5sums).

If you don't have g++ installed then you are missing the g++ build dependency, 
which is provided by the RPM gcc-c++ (yum install gcc-c++ should fix it.)

If you do have g++ installed then you could try running `ln -s /bin/g++ 
/bin/c++` as root, then retrying your build.
