At runtime, undefined symbol error from classes derived from Function1 class
 

Hi,


I am trying to make classes with template pattern from Function1 class with OpenFOAM 5.
compilation was done without any errors and warnings.


There is an error in runtime as follows:


simpleFoam: symbol lookup error: /home/abs/OpenFOAM/abs-6/platforms/linux64GccDPInt32Opt/lib/libFlowProfile.so: undefined symbol: _ZN4Foam14Function1Types15FlowProfileINS_6VectorId EEEC2ERKNS_4wordERKNS_10dictionaryE


classes are composed as follows:


Function1 <--- FlowProfile <--- uniformProfile


where FlowProfile is a abstract template class and uniformProfile is a derived class with vector binding.


without FlowProfile abstract class, I could make uniformProfile working in my simulation. But I want to make a group of my flow profiles with FlowProfile abstract class.



It is a kind of template class things, so I could not figure out what is going on and how to fix the runtime error. Any help will be appreciated.


FYI, source codes are listed below.
