Where can I download Microsoft VC project file to build CPP LIB for ANTLR?

Stephen Silber

Check in the distribution (2.7.1 and beyond) for antlr/lib/cpp/contrib/*. You will see MSCV6 project files.

Explanation:

Some caveats:

  • This is for Visual C++ 6.0. Use At Your Own Risk for other versions. (I think 4.0 doesn't have all the C++ language elements you need for Ric's code, so do yerselves a favor and score a copy of 6.)
  • The files that I mention in there can be found in the Files section of this list's website (http://groups.yahoo.com/group/antlr- interest). There you will find a zip file called "antlr_calc.zip". The full URL to that file is http://groups.yahoo.com/group/antlr- interest/files/antlr_calc.zip.
  • Using my libantlr project files, be warned that the debug version of the ANTLR lib weighs in at a whopping 2.8MB!
And on with the show...

First of all, put libantlr.dsw and libantlr.dsp into your antlr-2.7.1libcpp directory. Open up libantlr.dsw, and then do a Batch Build from the Build menu to build both the Debug and Release versions.

These project files output .lib files (not DLL's!), so they must be statically linked in the calc project. (We'll get there in a minute.) The debug version of the ANTLR library ends up as antlr-2.7.1libcpplibantrld.lib, and the release version ends up as libcpplibantlr.lib.

When you compile the ANTLR library, you will likely get 4 warnings. Ignore them--it'll work okay.

Now for the calc project!

Start by creating a new workspace project for a Win32 console program called calc. Make sure it's saved to the antlr-2.7.1examplescppcalc directory.

Add both the Main.cpp and calc.g files to the new project. VC++ won't have a clue how to handle calc.g yet.

First, let's add the ANTLR library to the project. Go the Project Settings (Project menu), click on the calc project at the top of the tree, and make sure it says "Win32 Debug". Now click on the Link tab, and in the Object/library modules box, add "antlr-2.7.1libcpplibantlrd.lib" (without the quotes) to the beginning. Now change the Settings For drop-down to "Win32 Release", and add "antlr-2.7.1libcpplibantlr.lib" to the same box. You've just added the ANTLR library to the project.

Leave that window open, because now we have to tell the project where the include files are for ANTLR!

Click on the "calc" entry at the top of the project tree in the Project Settings window, and then select "All Configurations" under the Settings For dropdown on the left. Then click on the C/C++ tab. Select "Preprocessor" under the Category dropdown.

Now, under "Additional include directories", add "antlr-2.7.1libcpp" without the quotes. Now click OK.

Getting the .g files to compile without any problems when you do a build is a tricky one, but it can be done.

First, right-click on the calc.g file in the project view, and click Settings. Now select "All Configurations" from the Settings For drop-down on the project window. Now click on the Custom Build tab.

Type something in for the description, like "Performing Custom Build Step on $(InputPath)".

Under Commands, type:
java antlr.Tool -o $(InputDir) $(InputPath)

Under Outputs, you have to put in the name of every file that ANTLR will generate from the .g file! So, for the calc project, the list will be:
CalcLexer.cpp
CalcLexer.hpp
CalcParser.cpp
CalcParser.hpp
CalcParserTokenTypes.hpp
CalcTreeWalker.cpp
CalcTreeWalker.hpp
Click OK.

Now right-click on calc.g in the Project view, and select "Compile calc.g". You should get a message that it's compiling, and then get zero errors.

Now all those .cpp and .hpp files are there! So add them to the project! Click on the Project menu, "Add to Project", then "Files", and select all the .cpp and .hpp files. (You'll have to change the "Files of type" dropdown to "All Files" to see the .hpp files.)

And after all that work, you're all done! Doing a Rebuild All will cause everything to be recompiled, including calc.g.

After all that, you'll probably think strongly about just doing it all on Unix using make! :-) I usually work in Cygwin now, just so I can use make on Windows ANTLR projects.
