(The first entry seems to be for the sources.) You will just need to modify makefiles/command line operations accordingly to give the correct executable names, which for example could be 'win_bison' and 'win_flex'.)ДЇirst, download Bison from here: Select 'bison-2.4.1-setup.exe', which was the 2nd entry when I last checked. We need to install Flex and Bison.ДЄ Google search will immediately serve up a Windows port, but not the one we want (although, any port should work correctly given my instructions in this tutorial series.

You define a (usually nested, and often recursive) sequence of rules, called a grammar, that describes valid input strings (source code files for a custom language you are implementing, for example), and provide associated 'actions' in C code, providing the underlying semantics for the programming language you are writing a compiler for.

You define patterns for tokens (language elements, such as keywords or regular expressions that define the valid format for variable names, and so forth), and then you define an associated fragment of C code for returning the next token to your parser in Bison. This series will focus on learning them enough to construct some basic text-input parsers.

The modern implementations of lex and yacc, flex and bison are for generating scanners, parsers and compilers. So, you've decided to get to grips with Flex and Bison on Windows.
