cant link liburt.so?

[nickhuangxinyu]

Hi,

I installed armadillo, and make lib use: make (without any link param) but the so file i complied out is not good. when i link it, it comes out: ./libURT.so: undefined reference to urt::UnitRoot<double>::set_trend()' ./libURT.so: undefined reference to urt::UnitRoot::compute_adf()' ./libURT.so: undefined reference to urt::UnitRoot<float>::pvalue()' ./libURT.so: undefined reference to urt::UnitRoot::gls_detrend()' ./libURT.so: undefined reference to urt::UnitRoot<double>::show()' ./libURT.so: undefined reference to urt::UnitRoot::pvalue()' ./libURT.so: undefined reference to urt::UnitRoot<double>::set_method()' ./libURT.so: undefined reference to urt::UnitRoot::set_lags()' ./libURT.so: undefined reference to urt::UnitRoot<double>::adf_regression()' ./libURT.so: undefined reference to urt::UnitRoot::set_trend()'

but i confirmed, all cpp file is compiled, can you help on this?
