[odb-users] Error when trying to compile with odb

[Sandgrav Morten]

Hi,

I have started to look at odb, but when I tried to compile the first example in the manual, person.hxx, I got an error:
odb -d mysql --generate-query person.hxx
cc1plus: error: cannot load plugin /usr/bin/odb.so: /usr/bin/odb.so: undefined symbol: tree_code_type

I am working on docker, so I have attached the dockerfile and as I said, the file I am trying to compile is person.hxx:
// person.hxx
//

#include <string>

#include <odb/core.hxx>     // (1)

#pragma db object           // (2)
class person
{

private:
  person () {}              // (3)

  friend class odb::access; // (4)

  #pragma db id auto        // (5)
  unsigned long long id_;   // (5)

  std::string first_;
  std::string last_;
  unsigned short age_;
};

What am I doing wrong?
