Hello, I am using Fedora 10 on a x86_64 maching with boost-1.34.1-17. I am getting the following errors when I try to compile QuantlabAddin-0.9.7. In file included from serialization_abcd.cpp:31: /usr/include/boost/serialization/vector.hpp: At global scope: /usr/include/boost/serialization/vector.hpp:126: error: redefinition of 'struct boost::serialization::implementation_level<std::vector<long int, std::allocator<long int> > >' /usr/include/boost/serialization/vector.hpp:126: error: previous definition of 'struct boost::serialization::implementation_level<std::vector<long int, std::allocator<long int> > >' /usr/include/boost/serialization/vector.hpp:126: error: redefinition of 'struct boost::serialization::implementation_level<std::vector<long unsigned int, std::allocator<long unsigned int> > >' /usr/include/boost/serialization/vector.hpp:126: error: previous definition of 'struct boost::serialization::implementation_level<std::vector<long unsigned int, std::allocator<long unsigned int> > >' make[1]: *** [serialization_abcd.lo] Error 1 make[1]: Leaving directory `/mnt/nfs/192.168.1.2/home/pmcevoy/Download/Quantlib/QuantLibAddin-0.9.7/qlo/serialization/register' make: *** [install-recursive] Error 1 Has anyone else run into this problem? If so do you have a fix? Thanks for the help, Patrick
