To exp.y, right before %token EVEN ODD in order to have an error free compilation. it's short, simple and addresses the issue stated in its title (thumbs up for that)Īnyway, I take the liberty to add the following: for those of you who are using GCC "4.5.0 20100311 (experimental)" (like me) you may want to add You can use windows flex and bison with minimal dependencies from Nice article bro, I really like your technical articles, but why not just use Cygwin and then build the sources? Sir I am studying compiler design and i am be very much thanking for your help with lex and yacc

Update: Here's a Zip file of FLEX, BISON and the Source Code used in this post. Do try out Linux distros as well (infact, I'd highly recommend you try a few before deciding which suits you best! Most distros are free!), but don't get dragged down by an environment! An OS is simply a tool to enable you, the developer, to work your magic! :) PPS Yes, I'm a FOSS/Linux enthusiast, but that doesn't mean I have to praise Linux all day long! Projects like GNUWin, which take code to the masses, are nothing short of brilliant! Linux distributions have so many advantages over Windows for any real developer, but I honestly believe every developer has the right to " choose" his/her development OS and environment, be it PC, Linux or Mac. The number of packages that they've ported to Windows is amazing. PS The GnuWin project is a superawesome project which " provides ports of tools with a GNU or similar open source license, to Windows". A simple example, but I guess it gets the point through! For and even number input, it prints out "EVEN NUMBER" and exits and "ODD NUMBER" is printed for odd numbers. Now just run the program ( through the command prompt itself). And generates a executable named a.exe (To use a different name, change last command to " gcc lex.yy.c y.tab.c -o nameofexecutable.exe" ) Note that the final step compiles the C files generated by FLEX and BISON. Now in the CMD prompt, navigate to the folder where the exp.l and exp.y files are and run the following commands:Īt each step, assuming all is well, you won't get any output. Similarly create a YACC file as well, say "exp.y" and edit it as followsĮVEN That's it! You now have a Bison and Flex set up! Now for some coding! :)Ĭreate a Lex file, let's say "exp.l" and open it up in your favorite text editor (read: Notepad++) If you do not get the output as above, restart your system and try again.

Incase you don't know how to go about this, see how to do it on Windows XP, Windows Vista and Windows 7. I use ' C:\GNUWin32' for FLEX and BISON and ' C:\CodeBlocks' for Code::Blocksĥ) Now add the BIN folders of both folders into your PATH variable.
#Mingw yacc install#
It's recommended to install in folders WITHOUT spaces in their names. I recommend DevCPP or Code::BlocksĤ) Install all 3.

Here's how to set up FLEX and BISON on Windows systemsģ) Download a C/C++ Compiler ( If you say TurboC, I'll reach out through the monitor and thump your head). Sticking with the " When in doubt, try another hole" philosophy, I just googled around a little and came up with a much easier solution. NOTE: When people say they use LEX and YACC, almost always, what they mean is FLEX (Which is an alternative to Lex) and BISON (which is part of the GNU project) / BYACC respectively. In many cases, people actually downloaded entire distro DVDs just for LEX/YACC! Since LEX and YACC are both originally developed for the *nix OSes ( read: Linux), there was a sudden rush of classmates downloading linux distros ( Fedora being the default choice as it's used on lab systems). We've just started compiler design as part of the Language Translators subject at college and a practical aspect of it involves using LEX and YACC for Grammar Lexical Analysis and Parser Generation.
