How can I compare performance of BerkeleyDB and MySQL with 100 milion records

I have installed on my machine (Ubuntu 18.04 and BerkeleyDB 18.1)

But when I run hello world:

``` vv@vv-ThinkPad-T450:~/test$ gcc hello2.cpp -o hello2 -I /usr/local/berkeleydb/include/ /tmp/ccoElaRL.o: In function `main': hello2.cpp:(.text+0x3d): undefined reference to `Db::Db(DbEnv, unsigned int)' hello2.cpp:(.text+0x7c): undefined reference to `Db::open(DbTxn, char const, char const, DBTYPE, unsigned int, int)' hello2.cpp:(.text+0x8f): undefined reference to `Db::~Db()' hello2.cpp:(.text+0xc3): undefined reference to `Db::~Db()' hello2.cpp:(.text+0xd6): undefined reference to `__cxa_begin_catch' hello2.cpp:(.text+0xe2): undefined reference to `__cxa_end_catch' hello2.cpp:(.text+0xec): undefined reference to `__cxa_begin_catch' hello2.cpp:(.text+0xf8): undefined reference to `__cxa_end_catch' /tmp/ccoElaRL.o: In function `__static_initialization_and_destruction_0(int, int)': hello2.cpp:(.text+0x12e): undefined reference to `std::ios_base::Init::Init()' hello2.cpp:(.text+0x143): undefined reference to `std::ios_base::Init::~Init()' /tmp/ccoElaRL.o:(.data.rel.local.DW.ref._ZTI11DbException[DW.ref._ZTI11DbException]+0x0): undefined reference to `typeinfo for DbException' /tmp/ccoElaRL.o:(.data.rel.local.DW.ref._ZTISt9exception[DW.ref._ZTISt9exception]+0x0): undefined reference to `typeinfo for std::exception' /tmp/ccoElaRL.o:(.data.rel.local.DW.ref.__gxx_personality_v0[DW.ref.__gxx_personality_v0]+0x0): undefined reference to `__gxx_personality_v0' collect2: error: ld returned 1 exit status

```

Folder code:

/home/test/hello.cpp

and I run by command: gcc hello.cpp -o hello -I /usr/local/berkeleydb/include/
