Hi all,

I was trying to build the new version of OSRA, and I encountered something
that I couldn't find a quick route around.  I built all of the needed
dependancies without issue, but during the compilation of the main
application I got the following:

osra_reaction.cpp: In function ‘std::string convert_page_to_reaction(const
std::vector<std::basic_string<char> >&, const string&, const
std::vector<int>&, const std::vector<int>&, std::string, bool)’:

make[2]: *** [osra_reaction.o] Error 1

I read that with a more modern version of gcc/g++ that I might have to add
a flag to tell the compiler to go back and use an older interpretation of
C++.  That also failed.  Has anyone else seen this?

Thanks,
Matthew
