I'm not sure if the problem is more suitable for StackOverflow or AskUbuntu, but I will ask. I have two virtual machines. On one Ubuntu 14.04 LTS and the other Ubuntu 16.04 LST. On both installed Oracle Instant Client 12.1 in the following way:
arkadiuszg@ubuntu:~/install/oracle$ ls -1
oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm
arkadiuszg@ubuntu:~/install/oracle$ sudo alien -i oracle-instantclient12.1-*
arkadiuszg@ubuntu:~/install/oracle$ cd /etc/ld.so.conf.d/
arkadiuszg@ubuntu:/etc/ld.so.conf.d$ sudo touch oracle-instantclient12.1.conf
arkadiuszg@ubuntu:/etc/ld.so.conf.d$ sudo vi oracle-instantclient12.1.conf
In created file I type:
/usr/lib/oracle/12.1/client64/lib
And finally:
arkadiuszg@ubuntu:/etc/ld.so.conf.d$ sudo ldconfig
I am using C++ tools like: g++, make, gdb. Compiling the project runs on both machines correctly, but the problem is linking on Ubuntu 16.04. I keep getting the following errors:
DbConnection.cpp:(.text+0x536): undefined reference to `oracle::occi::Date::toText(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) const'
build/Release/GNU-Linux/database/DbConnection.o: In function `CDbConnection::connect()':

collect2: error: ld returned 1 exit status
When I do exactly this same on Ubuntu 14.04, then everything is OK. Compiling and linking ends with success.
Can anybody help me, please...
