Nyacc and guile-nearly-3.0

Nyacc and guile-nearly-3.0

[-- Attachment #1: Type: text/plain, Size: 290 bytes --]

Hi,

to anyone "in the know": is it worth to give nyacc a spin under
Guile nearly-3.0 (i.e. >= 2.9.5)?

I know the "configure" precludes that, but it's fairly obvious
how to jump that fence. Is it a total loss of time -- or worth
a try?

Thanks for any insight, cheers

Well, I tried, this is a small progress report. First munged
_guile_versions_to_search in nyacc's configure script to contain
2.9.5 (that's what my guile --version says). Configure bails
out with:

  configure: error: found development files for Guile 2.9.5, but /usr/local/bin/guile has effective version 3.0

(FWIW, there's an /usr/local/lib/pkgconfig/guile-3.0.pc). Now
setting _guile_versions_to_search in said script bails out with

  checking for Guile version >= 3.0... configure: error: Guile 3.0 required, but 2.9.5 found

So it seems my Guile is schizophrenic: under some aspect it
reports 3.0 ("effective" version), under some aspect it's
2.9.5 (--version version, to put some name on it).

I haven't given up yet, though :-)

Cheers & thanks

Look at etc/README.  Maybe edit etc/configure.ac and rerun as in the README.

I'm building 2.9.5 now but running into errors (ubuntu 18.04):

Ouch. A segmentation fault in bash :-o

Let's see what happens here...

Hm. Same confusion. Adding 3.0 to GUILE_PKG, like so:

  GUILE_PKG([3.0 2.2 2.0])

yields, at configure time:

  tomas@trotzki:~/src/guile/nyacc$ ./configure
  checking for pkg-config... /usr/bin/pkg-config
  checking pkg-config is at least version 0.9.0... yes
  configure: checking for guile 3.0
  configure: found guile 3.0
  checking for guile... /usr/local/bin/guile
  checking for Guile version >= 3.0... configure: error: Guile 3.0 required, but 2.9.5 found

Inserting 2.9.5 in configure.ac's GUILE_PKG, like so:

  GUILE_PKG([2.9.5 2.2 2.0])

yields, again at configure time:

  tomas@trotzki:~/src/guile/nyacc$ ./configure
  checking for pkg-config... /usr/bin/pkg-config
  checking pkg-config is at least version 0.9.0... yes
  configure: checking for guile 3.0
  configure: found guile 3.0
  checking for guile... /usr/local/bin/guile
  checking for Guile version >= 3.0... configure: error: Guile 3.0 required, but 2.9.5 found
  tomas@trotzki:~/src/guile/nyacc$ ( cd etc && autoconf -o ../configure )
  tomas@trotzki:~/src/guile/nyacc$ ./configure
  checking for pkg-config... /usr/bin/pkg-config
  checking pkg-config is at least version 0.9.0... yes
  configure: checking for guile 2.9.5
  configure: found guile 2.9.5
  checking for guile... /usr/local/bin/guile
  configure: error: found development files for Guile 2.9.5, but /usr/local/bin/guile has effective version 3.0

It seems I've got a schizophrenic Guile. It somehow reports
an "effective version" 3.0 (the pkg config file in /usr/local/lib
is a guile-3.0.pc, actually), but if you ask guile itself, it
reports 2.9.5.

I don't exactly know where configure has this "effective version"
from, but I dimly remember Andy mumbling about setting Guile's
effective version to 3.0, since 2.9.5 is already a pre-3.

Hmmm. I'll try to poke at it some more tomorrow...

Cheers & thanks

2.9.5 build segfault on Ubuntu 18.04 [WAS: Nyacc and guile-nearly-3.0 (progress report)]

So, as a random check, I first verified that I could reproduce the above 
error at the command line.  I did.

Then I removed "-Oresolve-primitives" and it compiled without error.   
Any help?

Do you know when your bash was compiled? I started getting such errors
with externally compiled binaries about two months ago and have been
unable to resolve that so far.

(i.e. the Firefox compiled for Ubuntu does not work anymore)

To complement that, here what "my" Guile says:

  tomas@trotzki:~$ guile
  GNU Guile 2.9.5
  Copyright (C) 1995-2019 Free Software Foundation, Inc.
  
  Guile comes with ABSOLUTELY NO WARRANTY; for details type `,show w'.
  This program is free software, and you are welcome to redistribute it
  under certain conditions; type `,show c' for details.
  
  Enter `,help' for help.
  scheme@(guile-user)> (version)
  $1 = "2.9.5"
  scheme@(guile-user)> (effective-version)
  $2 = "3.0"
  scheme@(guile-user)> (major-version)
  $3 = "2"
  scheme@(guile-user)> (minor-version)
  $4 = "9"
  scheme@(guile-user)> (micro-version)
  $5 = "5"

This is compiled off git, specifically:

  a12e862be (HEAD -> master, tag: v2.9.5, origin/master, origin/HEAD) GNU Guile 2.9.5.

Not very surprising, so far. Version is 2.9.5, "effective version" is
3.0.

As seen from my corner of reality, nyacc's configury can't cope with
the fact that Guile's version and effective version are different.

Now on your side, Mark, configury seems to get past that point (and
you run into "real" stuff, like the new shiny Guile compiler doing
"too much" at compile time -- that kind of issues one might expect).

The segfault is not in bash.  I was able to re-create the segfault from 
the (bash) command-line.

OK -- compiles successfully now. I realize in hindsight that
my answers sometimes went (only) to guile-devel, so I re-quote
that one where I "solved" configury:

So far, so good. Now it compiles "cleanly" (but there's no -Oresolve-primitives
option in sight in all of the compile; no idea why).

A cursory test (with the example from the man page)
shows signs of life. Yay!

IIRC nyacc is part of guix mes bootstrap tooling, so it is a requirement to
bootstrap guix with guile 2.9+

It's working for me now. It was mostly "driver error", but since the
thread went a bit out of control and got partially split between
here and guile-devel@, I restate. Setting

  GUILE_PKG([3.0])
  GUILE_PROGS([2.9.5])

in etc/configure.ac (and invoking autoconf -o ../configure, as stated
in /etc/README) did the trick for me.

Matt says that he had to remove "-Oresolve-primitives" from the compiler
options. I hadn't -- but I suspect this option isn't set by default...

I apologize if I generated confusion.  I was intending to build 2.9.5 to 
help debug the nyacc issue.
The segfault I ran into was in building guile-2.9.5.  It is uncorrelated 
with the nyacc issue.

Now everything is clear. Thanks, Mark. And thanks also for setting
