I wrote a code in c++, using a template class.
When I put all function and declaration in one file (no project) it was just fine. But when I divided it to few files (using project) I had a linker error:
"undefined symbol a<int>::show_num() in module appl.cpp"
when "a" is the class template, and "show_num()" is a public function in it.
the same goes very well when I don't use the template.
Any idea ????????
please if can add an example.
