Trying to include a header in Visual Studio 2010, unable to compile error LNK2019

I started a new project for that alone under "empty project". I was trying to include a combinatronics algorithm from
http://www.aconnect.de/friends/editions/computer/combinatoricode_e.html

the only files in the project are "main.cpp" which is a copy paste of http://www.aconnect.de/friends/editions/computer/generate/comb_norep_lex_example.c

and a header "_generate.h" which is directly copied from http://www.aconnect.de/friends/editions/computer/generate/_generate.h

the errors I get are:

Error 1 error LNK2019: unresolved external symbol "int __cdecl gen_comb_norep_lex_next(unsigned char *,unsigned char,unsigned char)" (?gen_comb_norep_lex_next@@YAHPAEEE@Z) referenced in function _main C:\Users\user\Documents\pr1\pr2\pr2\main.obj pr2

Error 2 error LNK2019: unresolved external symbol "int __cdecl gen_comb_norep_lex_init(unsigned char *,unsigned char,unsigned char)" (?gen_comb_norep_lex_init@@YAHPAEEE@Z) referenced in function _main C:\Users\user\Documents\pr1\pr2\pr2\main.obj pr2

I have looked through similar questions, but none of the solutions worked for me.

Thanks

The header file only declares the functions, you need a source file where those functions are defined as well, and include that in your project. – Some programmer dude

Joachim Pileborg comment is correct, I didn't add the actual algorithm. My bad.
