Adding python.h library about frvt HOT 4 CLOSED

You will need link any external dependencies directly to your core submission library. The only library that NIST will link against is your core submission library (i.e. libfrvt11_xxx_xxx.so). Additionally, you will need to provide all Python dependencies in your submission package to us.

Could you please guide me to link the dependencies to my core submission library?

I am getting this error, I have tried find_package(Python3 COMPONENTS Interpreter Development) from 11/CmakeLists.txt but still I am getting this error. Where shall I link the Python library to my submission library?

You can't assume that python3 will be installed on our systems, because it is not. You will need to place all of your python dependencies (e.g., libpython3.6m.so) into your ./lib folder and link against them when you build YOUR shared library. You can use rpath=$ORIGIN, but you need to link your submission library against any 3rd party libraries that are required. For example, in your CMakeLists.txt:

set (CMAKE_SHARED_LINKER_FLAGS "-Wl,-rpath,$ORIGIN")
add_library (libfrvt_11_biocube_001 SHARED yourSourceCode.cpp)
target_link_libraries(libfrvt_11_biocube_001 libpython3.6m.so thirdpartylib1.so thirdpartylib2.so thirdpartylib3.so)
