I have three files:

vhdl.c generated by bison from vhdl.y
main.c application to use the parser
on linux i havn't error, in fact flex and bison are installed on linux.
but i d'ont find a version of flex and bison on win32, just flex.exe and bison.exe to generate c files.
How can i include the lexer specification file used by Flex to generate the lexer code,

vhdl.obj : error LNK2001: unresolved external symbol _yylex

Note: these file work on linux and in the link i hav'nt problem, i use yhe -lfl option to link. But in windows, i don't know the problem
Can you please help me!! -
But this code work well on linux. The problem on linux we use the option -lfl in the link. But on windows i don't know a flex library.
I want to link files generated by flex and bison on visual studio C++.
but i have this error:
vhdl.obj : error LNK2001: unresolved external symbol _yylex
I think that there is a flex library missed. But i don't find a win32 version of flex library.
Can you please help me...Leave a comment:

vhdl.o is from vhdl.c, this file is generated by bison. My application is a vhdl parser....Leave a comment:
