Makefile: For building Flex/Bison template

Posted 08-19-2017 at 03:16 AM by astrogeek

Flex / Bison Project Template, project Makefile.

Save this make source to a file named Makefile in the same directory with lexer and parser source files. The build targets are described in the template project README file.

To build a working parser simply run make in the project directory.

To generate a graph of the parser and display it in an X11 window, run make dotx11.

Code:
#A simple makefile for building Flex / Bison template

fbproject: fbproject.y fbproject.l fbproject.tab.h lex.yy.c
        gcc -g -Wall -o fbproject lex.yy.c fbproject.tab.c -lfl

lex.yy.c: fbproject.l fbproject.tab.h
        flex fbproject.l

fbproject.tab.h: fbproject.y
        bison -vd fbproject.y

#The dot target creates fbproject.dot graphviz graph
#To generate PNG run dot -Tpng fbproject.dot
dotx11: dot
        dot -Tx11 fbproject.dot &
dotpng: dot
        dot -Tpng fbproject.dot >fbproject.png
dot: fbproject.y
        bison -vd fbproject.y --graph

clean:
        rm -f fbproject fbproject.lex.h fbproject.tab.* fbproject.dot fbproject.png lex.yy.c fbproject.output
