I am trying to compile the latest stable c++ driver(26compact branch), https://github.com/mongodb/mongo-cxx-driver
I have built boost from source as:
$ ./bootstrap.sh --help
$ ./bootstrap.sh
$ ./b2 install
and the c++ driver as:
$ scons --use-system-boost --sharedclient --full install-mongoclient
Finally libmongoclient.a has been generated, but when generating libmongclient.so I get something like this:
