   Http://www.bumblebeesoftware.com/downloads.htm.
   After installing the software, set the path of the system environment variable and add the installation bin directory in the path attribute. Take my installation as an example and add it after the previous path attribute. D: /program files/Parser Generator 2/bin
   In the Console Command window, enter Alex and ayacc to check whether the two commands can be found. If the two commands cannot be found, the environment variable settings must be incorrect.
2. Vc.net Configuration
   The following uses vc.net as an example to describe the configuration.
   1) Open the vc.net program, open the menu "Tools" => "options", and open the "options" dialog box.
   2) Select "Projects" => "VC ++ directory" on the left of the Options dialog box"
   In the directory where the following content is displayed (S) "Select" executable files "from the drop-down list and add a line" D:/program files/Parser Generator 2/bin "to the directory list below"
   In the directory where the following content is displayed (S) "Select" include files "from the drop-down list and add a line to the directory list below:" D:/program files/Parser Generator 2/CPP/include"
   In the directory where the following content is displayed (S) "Select" library files "from the drop-down list and add a line to the directory list below:" D:/program files/Parser Generator 2/CPP/lib/msvc32"
   In the directory where the following content is displayed (S) "Select" source file "from the drop-down list and add a line to the directory list below." D:/program files/Parser Generator 2/CPP/source"
3. Example
   Use vc.net to create a console Project
   Select a project, right-click the project, and select "properties" from the shortcut menu. Alternatively, select "project" => "properties" from the shortcut menu to open the Project Properties dialog box.
   1) Select "attribute configuration" => "C/C ++" => "preprocessing" on the left. In the list on the right, add a yydebug macro definition in the pre-processor definition line, which is separated by a; number by another macro definition.
   2) Select "Property configuration" => "connector" => "input" on the left, and add YLD to "add dependency" in the list on the right. lib or ylmtrid. lib (ylmtrid. lib is multi-thread, YLD. lib is a single thread)
   3) Copy calc from the D:/program files/Parser Generator 2/CPP/examples/calc directory. Y file to the project directory, open the console, enter the project Calc. run the command ayacc Calc. y. If it succeeds, you will see a calc. c file generation. set Calc. C is added to the project, and then compiled to generate executable programs.
   4) configure the compilation option to automatically convert the. Y. l file.
   Select. Y file, right-click the menu => "properties" to open the Properties dialog box, select "Custom generation step" in the Properties dialog box, and enter ayacc Calc. y, input calc in "output. c; in this way, you can compile the project according to calc. the y file automatically generates Calc. c file ,. l file generation and configuration methods are similar.
4. End
   I have successfully generated a program according to the above steps, without any errors. The configuration of vc6.0 is similar. If there is anything wrong, please correct me.
