[gentoo-dev] re2c woes - badly broken with gcc 3.x - offering help, possible ebuild maintainership

[Elfyn McBratney]

Hash: SHA1

Hello devs,

Before I begin, sorry if I should have sent this to the -user list..  Please 
forward it there/moan at me if so. :)

At the moment, re2c is completely broken w.r.t. gcc 3.x.  And as most people 
are living on the bleedin' edge (i.e., not using gcc 2.x) re2c is completely 
broken for them.

So, I propose the maintainers of php*-cvs/re2c do one of:-

  1)  Pull from portage.  Drastic, yes, but why have ebuilds in the tree if
      the wont compile for most gentoo users?

  2)  Fix them.  I'll try as hard as I can (I've done most of the porting of
      re2c (current ver in portage), I'm just left with a few C++ idioms..) to
      fix it up so it's usable.

That's it. :)

Thanks,
Elfyn

We know.  Bug #43449 covers this.

I believe that re2c is required for something or other to do with php5.  
Coredumb's really the best person to answer that, but he doesn't seem to be 
around much lately :(

Why duplicate work?  Take a look at re2c.org ... there's already a project 
underway to deal with this, which includes important patches from the PHP 
developers.

If you update bug #43449 with an ebuild for re2c.org's version, I'll happily 
take a look at it.

Best regards,
Stu

Yep, it's used to build parts of the perser.

I have been looking around but didn't come across re2c.org..  Thanks! :)

I'll give it a shot :)

You need re2c to build from CVS. :)  Well, you need it if you change the .re 
files which I do. 8)

OK, I've got a patch ready for bug #43449.  This patch applies to re2c.org's 
0.9.1 (based on the patch already in portage 8)  It's available here (as I 
couldn't reach bugs.gentoo.org - crap isp ;)

  http://people.emcb.co.uk/beu/devo/gentoo/re2c/re2c-ebuild.patch
  http://people.emcb.co.uk/beu/devo/gentoo/re2c/files/0.9.1-patch

(Add a .gz to the last one for gzip'ed patch.)

I know the Makefile kludge is bad! :)  I'm going to try and work on a solution 
upstream, but in the mean time re2c builds and works (haven't tried with gcc2 
yet - will do that today).

The ebuild does a double `emake || die' because the first time re2c is 
compiled is uses the pre-processed `scanner.cc' (bootstrap) the second is 
done using the just-compiled re2c.  Hrmm..

Replying to myself as I've had some sleep and have now come to the conclusion 
my patch is fit only for the bin. :)

I'm going to get on the re2c mailing list and try and push most of this 
upstream (the bulk are general portability changes, not really gentoo 
specific).  I'll comment on bug #43449 when I have something that isn't 
kludge. ;)

Sorry for the noise 8)

The RPM eclass can be used to extract data from RPMs.  If they provide a
source RPM, then you shouldn't have very many issues with creating an
ebuild to extract and build the software.

If they don't provide source RPM's you can still use the eclass to
create a binary ebuild.

Paul

Heh - that Marcus from the php.net dev team?  Figures ;-)

We can do that.  Look at nxserver.eclass - that's one example that does this.  
There are probably better ones in the Portage tree ;-)

We can do that instead.  I guess it comes down to how often they plan on 
updating the RPMs - and whether there are any binary compatibility problems.  
CVS snapshots might just be the way to go.

Is there anything we can do to help you right now?

OK, I have something..  the only problem I see is that the re2c.org people 
won't be doing releases.  They'll be working from CVS only.  Marcus Boerger 
asked this:

  ". . .It would also be nice if gentoo could go with RPMs we provide from CVS
  now (see README.in file)."

I replied to Marcus saying that I'd ask (but that I was doubtful anout using 
RPM's :)

So, what to do?

I'm working on a new ebuild that uses a cvs snapshot (to be downloaded from a 
distfiles mirror) that would seem the most logical way to go..  the only 
problem with that is that a dev will have to update the snap every couple of 
weeks/month. 8)

AFAICS, they do not (provide a SRPM that is).  I will ask.  They provide a 
spec and a script to make the RPM, though.

I'm not familiar with the rpm eclass..  I'll have a look at it.  Thanks.

working completely from CVS, so if you wanted an RPM it'd be a DIY job. :)

I'm just testing my ebuild, so if that works, it might be bug #43449 closing
