Yacc and bison in visual studio

Question

I am going to transfer the project C, which was for unix in windows. Until now, I could compile it, but not build it. The problem I am getting is that some of the functions declared in the header files are defined in the yacc files. So I get the following errors:

 error LNK2001: unresolved external symbol function_name

I am adding .y and .l files to the project source directory. I think I could not transfer the yacc files to the Windows version or I am doing something stupid. I am looking for him on the Internet, but could not get the right study guide for him. Could you tell me

• How can I add .y or .l files to a project.
• How can I make these files compatible with windows?
• How to link them with other object files.

EDIT

I tried changing files .lto files .yy.cusing flex.exe.Following - this is the command for it

     c:\> flex.exe name.l

, flex.exe name.l C;>. .l .y(previously present for parsing in unix system) .yy.c(corrsonding yacc file for windows) .

 Can't read the header file  parserheaderfile.h 

, bison unix . , bison windows. , , ?
