-I've succesfully build 1.31b3 with djgpp for DOS and MSVC 2.0 for Windows
-NT. The only (minor) problem I had was that GNU make (version 3.71, in the
-djgpp port) complained about "multiple targets" in both the antlr and dlg
-makefiles. I got around the error by, in each makefile, commenting out the
-$(SRC) dependency, for example:
-
- antlr: $(OBJ) #$(SRC)
-
-I don't know why this is happenning, since you haven't changed that part of
-the makefile at all, and I think this used to work ok...
-
-Here are the makefiles I built from within the MSVC 2.0 environment for antlr
-and dlg and Windows NT console executables. Please feel free to pass them
-on. Of course, as soon as 1.31 "goes gold", I will send you nice new
-binaries. I'm not going to bother to keep doing both Borland and djgpp for
-DOS however. Instead, I'll just keep the djgpp version up to date and also
-provide WinNT binaries.

- How to port PCCTS 1.10 (and 1.32 hopefully) to Visual C++
-
- By
-
- John Hall <jhall@ivy.wpi.edu>
-
-Here is how to compile an ANTLR grammar in Visual C++. These steps
-describe how to have your ANTLR grammar parse the input file the user
-selects when they choose File Open in your Windows application. (Even
-if you aren't using Visual C++, the steps should be portable enough to
-other compilers.)
-
- * Make sure that ANTLR and DLG generate ANSI code (use the -ga
- switch).
-
- * Set the following compiler flags in Visual C++ (these are in the
- Memory Model category of the compiler options in the Project
- Options menu):
-
- FLAG MEANING
- ==== ==============================================================
- /AL Large memory model (multiple data segments; data items must be
- smaller than 64K).
-
- /Gtn Allocates all items whose size is greater than or equal to n
- in a new data segment. (I let n be 256: /Gt256.)
-
- /Gx- All references to data items are done with far addressing in
- case they are placed in a far segment.
-
- * Add the following member variable to the attributes section of your
- derived CDocument class (you will need to make sure you also
- include stdio.h):
-
- FILE *fp;
-
- * Add the following method to your derived CDocument class:
-
- BOOL CAppDoc::OnOpenDocument(const char* pszPathName)
- {
- // Call CDocument's OnOpenDocument to do housekeeping for us
- // DON'T add anything to the loading section of Serialize
- if (!CDocument::OnOpenDocument(pszPathName))
- return FALSE;
-
- // Open input file
- if ((fp = fopen(pszPathName, "r")) == NULL)
- return FALSE;
-
- // Parse input file
- ANTLR(start(), fp);
-
- // Close input file
- fclose(fp);
- return TRUE;
- }
-
- (Note: additional code may be necessary, depending on your parser.
- For example, if your parser uses PCCTS's symbol table library, you
- will need to insert calls to zzs_init and zzs_done.)
-
- * Compile the generated C files as C++ files. (I renamed the files
- to have a .CPP extension to fool Visual C++ into thinking they were
- C++ files. One might also use the /Tp switch, but that switch
- requires you separately include the filename.) [I used this step
- as an easy out for all the external linking errors I was getting
- that I couldn't fix by declaring things extern "C".]
-
- * Make sure the __STDC__ portion of the generated files gets
- compiled. (Either define __STDC__ yourself or else change all
- occurrences of __STDC__ to __cplusplus in the generated files. You
- can define __STDC__ in the Preprocessor category of the compiler
- options.)
-
- ================================================================
- = Note 23-Sep-97: This is probably not necessary any more. =
- = With 1.33MRxxx the use of __STDC__ was replaced with the =
- = macro __USE_PROTOS to control the compilation of prototypes. =
- ================================================================
-
-That last step is important for Visual C++, but may not apply to other
-compilers. For C++ compilers, whether __STDC__ is defined is
-implementation dependent (ARM, page 379). Apparently, Visual C++ does
-not to define it; it also does not support "old style" C function
-definitions (which is okay, according to page 404 of the ARM). Those
-two things together caused problems when trying to port the code.
-When it saw this:
-
-#ifdef __STDC__
-void
-globals(AST **_root)
-#else
-globals(_root)
-AST **_root;
-#endif
-
-it skipped the __STDC__ section and tried to process the "old style"
-function definition, where it choked.
-
-When you finally get your parser to compile and link without error,
-you may get General Protection Fault errors at run time. The problem
-I had was that a NULL was passed to a variable argument function
-without an explicit cast. The function grabbed a pointer (32-bits)
-off the stack using va_arg, but the NULL was passed silently as the
-integer 0 (16 bits), making the resulting pointer was invalid. (This
-was in PCCTS's sample C parser.)
-
-There is one other thing I might suggest to help you avoid a run-time
-error. Make sure you redefine the default error reporting function,
-zzsyn. To do this, put "#define USER_ZZSYN" in your #header section
-and put your own zzsyn somewhere. You can then pop up a MessageBox or
-print the error to some output window.
