yes it is written in Java.

You might also check out :
PCCTS -- This the predecessor to ANLTr, but it is written in C++.

There is a nice list of compiler compilers here:

The only problem I see with this is the latest version of VC++ still has
weak template support, and as you already know, Spirit is very template
intensive. Have you checked out the BOOST library, to which Spirit was
resently added too? It has some nice workarounds for various compilers.

Thanks, I will check them out.

Well they say over in the spirit newsgroup that vc7.1 compiles very well,
but of course, the proof of the...

I tried different versions of spirit 1.6.1 (the latest stable release).
Could create a simple parser but when I wanted to use the ast templates it
failed, without that I don't think it is possible to write a (maintainable)
parser. The 1.7 release doesn't even compile, it gives a error in a certain
line.[color=blue]

Thanks, for your reply.

Hi,

AFAIK, 1.7 compiles cleanly on VC 7.1 (all regressions pass). Could you
be more specific with the compilation errors you are getting? I'd appreciate it
if you can post some code that exhibits the problem in Spirit's mailing list.
Rest assured, we are trying our best to make things work as smoothly as
possible.

Re: Best lex/yacc for C++?

Hi,

Thanks Joel four your reply and all your guys for working on spirit, I realy
love to just write C++ code and not have to mix C and/or precompile stuff.

I have got my VC7.1 version in. And it seems to compile fine (though I
didn't create any more than some simple things), but it did compile the same
example project that couldn't be compiled with VC6.0 and it works!

However with the VC6.0 the following errors are given as soon as I use ast
stuff (I could create a simple command line parser though) if you are
interested:

This is the ast_calc from the example section (the regular calc works fine
with VC6.0).

Compiling...
ast_calc.cpp
h:\include\boos t\spirit\tree\c ommon.hpp(207) : error C2984: 'node_iter_data '
: template parameters '' and '' do not match
h:\include\boos t\spirit\tree\c ommon.hpp(207) : see declaration of
'node_iter_data '
h:\include\boos t\spirit\tree\c ommon.hpp(534) : error C2989:
'tree_match_att r<class boost::referenc e_wrapper<T> >' : template class has
already been defined as a non-template class
h:\include\boos t\spirit\tree\c ommon.hpp(534) : error C2988: unrecognizable
template declaration/definition
h:\include\boos t\spirit\tree\c ommon.hpp(569) : fatal error C1903: unable to
recover from previous error(s); stopping compilation


Thanks for your great work,

Regards, Ron AF Greve
