Hi, everyone. I'm using CentOS 7 with devtoolset-7 to build ceph. However, I found that the list::size() in my ceph executables is still counting the number of nodes. It's so odd, I googled it, and found that this may have something to do with _GLIBCXX_USE_CXX11_ABI. But even if I explicitly set _GLIBCXX_USE_CXX11_ABI to 1 when building ceph, the problem remains. It seems that _GLIBCXX_USE_CXX11_ABI is set to 0 by gcc no matter how I build the source code, even with -D_GLIBCXX_USE_CXX11_ABI=1. Does anyone have any clue?
