I added at the end of ibvp.h: typedef ibvp<3> ibvp_obj; I added at the end of ibvp.cc: template class ibvp<3>;
Then in main.cc, I create the object as ibvp_obj irradiation; It is still returning exactly the same error of undefined reference. /home/sabyasachi/Documents/current_research/irradiated_materials/irradiated_tension_engg_400C/main.cc:96: error: undefined reference to 'ibvp<3>::ibvp()' /home/sabyasachi/Documents/current_research/irradiated_materials/irradiated_tension_engg_400C/main.cc:98: error: undefined reference to 'ibvp<3>::run()' /home/sabyasachi/Documents/current_research/irradiated_materials/irradiated_tension_engg_400C/main.cc:128: error: undefined reference to 'ibvp<3>::~ibvp()' /home/sabyasachi/Documents/current_research/irradiated_materials/irradiated_tension_engg_400C/main.cc:128: error: undefined reference to 'ibvp<3>::~ibvp()' collect2: error: ld returned 1 exit status make[2]: *** [CMakeFiles/main.dir/build.make:132: main] Error 1 make[1]: *** [CMakeFiles/Makefile2:100: CMakeFiles/main.dir/all] Error 2 make: *** [Makefile:91: all] Error 2 I also tried template class ibvp_obj<3> at the end of .cc but still the same error.
