Legacy source is version:

commit 624146feb3bb74fe139b167af02d666e83f24e7d
Date: Sun Mar 15 18:04:25 2015 +0800

Command compiles legacy branch of C++ driver:

scons --sharedclient --extrapath=/home/chatsiri/sda1/workspacecpp/boost_1_57_0 --cpppath=/home/chatsiri/sda1/workspacecpp/boost_1_57_0 --libpath=/home/chatsiri/sda1/workspacecpp/boost_1_57_0/stage/lib --cxx=/usr/bin/g++-4.8 --cc=/usr/bin/gcc-4.8 --dbg=on --prefix=/home/chatsiri/sda1/workspacecpp/mongo-cxx-driver/build install

An example source code before was compiled to binary file.

class mongo_conector{
public:
mongo_conector()

{ mongo::client::initialize(); // Cannot intial show SIGSEGV,Segmentation fault }

...
};
