The link errors I get are the following: build/jsummarizer.o:jsummarizer.cc:(.text $_ZN7inxight10summarizerD1Ev[inxight::summarizer::~summarizer()] +0x4f): undefined reference to `inxight::delete_summarizer(inxight::summarizer_interface*)'

They are all virtual. Apparently, I have to implement them? FYI the "dlltool" I used was Anywhere PE, sorry, was using it in a generic sense. As you may have understood, this is a JNI project. I have done these before against dlls of unknown compilation. I am not trying make summarizer37.dll a part of the one I'm building, merely load it at run- time. The other link command-line I included in my original post worked. I may be confused about this, but thought that linking involved putting the code together in some way as a single exe or dll. Thought this is different from writing code which calls functions in a dll/lib/so, even though the calling code and the dll are compiled by different compilers. Am I completely off base on that?
