This is an example:

source:
 - main.cpp 
 - Foo.h 
 - Foo.cpp

<main.cpp>
call foo(i)
No symbol "foo" in current context.
call bar(i)
$1 = true
</main.cpp>

<Foo.h>
#ifndef FOO_H_
#define FOO_H_

template<typename T>
bool foo(T val);

bool bar(int val);

#endif /*FOO_H_*/

</Foo.h>

<Foo.cpp>
#include "Foo.h"
#include <iostream>


template<typename T>
bool foo(T val)
{
    std::cout << "Hello from foo" << std::endl;

    return true;
}

template bool foo(int); // instantiates foo<int>(int)

bool bar(int val)
{
    std::cout << "Hello from bar" << std::endl;

    return true;
}
</Foo.cpp>

gdb says
<gdb>
call foo(i) # the template function
No symbol "foo" in current context.
call bar(i)
$1 = true
<gdb>
