I'm working on a makefile to build the oo api examples.
Everything is fine, except for 05.user_metadata.cpp
Executing this:
c++ -c -Wall -g3 -std=c++11 -fno-rtti -I/opt/firebird/include/ \
05.user_metadata.cpp -o 05.user_metadata.o
produces this error:
05.user_metadata.cpp: In function ‘int main()’:
05.user_metadata.cpp:212:14: error: invalid new-expression of abstract class

05.user_metadata.cpp:46:7: note: because the following virtual functions
are pure within ‘MyMetadata’: class MyMetadata : public

Is this an error in the code or in my makefile?
