[antlr-interest] Re: ANTLR cpp-generated example crashes on Cygwin

[Dario Gonzalez]

Thanks Ric,

In the mean time I happily made ANTLR-cpp-generated files work on
Cygwin (with both MinGW and CygWin)... It seems that the cpp-example I
used is outdated regarding the ASTFactory-initialization-stuff (which
BTW, I've not understood very well, but I'm in the learning process).

Now my concern is with MSVC++ 6.0/SP5(Yes, I need it to work in both
CygWin and MSVC++): The first try of creating the library from
Klaren's snapshot, threw 1042 errs (here's only a taste):

...\lib\cpp\antlr\circularqueue.hpp(23) : error C2039: '_Vector_val' :
is not a member of 'std'
...\lib\cpp\antlr\circularqueue.hpp(23) : error C2143: syntax error :
missing ';' before '<'
...\lib\cpp\antlr\circularqueue.hpp(23) : error C2079: '_Vector_val'
uses undefined class 'std'
...\lib\cpp\antlr\circularqueue.hpp(23) : error C2059: syntax error : '<'
...\lib\cpp\antlr\circularqueue.hpp(23) : error C2027: use of
undefined type 'std'
        ...\lib\cpp\antlr\circularqueue.hpp(23) : see declaration of 'std'
...\lib\cpp\antlr\circularqueue.hpp(24) : error C2027: use of
undefined type 'std'
        ...\lib\cpp\antlr\circularqueue.hpp(23) : see declaration of 'std'
...\lib\cpp\antlr\circularqueue.hpp(24) : error C2143: syntax error :
missing ';' before '<'
...\lib\cpp\antlr\circularqueue.hpp(24) : error C2079: 'vector' uses
undefined class 'std'
...\lib\cpp\antlr\circularqueue.hpp(24) : error C2059: syntax error : '<'

Since the source of this errors were #conditional compilation, my
first reaction was to comment out all the lines that caused them. And
surprisingly it worked!, but I couldn't try it because the
ANTLR-generated CPP files had being produced with antlr2.7.2 (Abstract
classes weren't being fully imlplemented according to the headers of
the snapshot). So I tryed to compile the full test snapshot following
the same cygwing-recipe... it didn't work:

=============================
Making antlr ...
=============================
make[1]: Entering directory `/redo/antlr-20031029/antlr'
Makefile:77: warning: overriding commands for target `install'
/redo/antlr-20031029/scripts/Rules.make:383: warning: ignoring old
commands for tar

java.exe -cp "C:\cygwin\redo\antlr-20031029" antlr.Tool   antlr.g
Exception in thread "main" java.lang.NoClassDefFoundError: antlr/Tool
make[1]: *** [.antlr.g] Error 1
make[1]: Leaving directory `/redo/antlr-20031029/antlr'
make: *** [subdirs] Error 2

Obviously, the work-recipe doesn't apply...
So I'm stuck here. Please advice .
