Re: [IMP-dev] Wrapping of the use of read_pdb in EM module

[Daniel Russel <>]

C/C++ programs have to be linked against libraries that they use in  
addition to including the headers (it is kind of a dumb system).  
Without being linked against imp_atom, when you try to use the code,  
it can't find the imp_atom C++ library and so will fail to find a  
needed class.

In order to link imp_em against imp_atom, you need to add imp_atom to  
the list containing imp_core and imp_algebra in modules/em/SConscript.
