Re: Building Guilemacs

[Christopher Allan Webber]

If someone wanted to rebase the emacs side of the guile-emacs fork...
I think that would be great :)

Re: Building Guilemacs

[Wilfred Hughes]

Digging some more, I think the issue is
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=24065 . Emacs trunk is
depending on undefined C behaviour, which gcc 5 has started optimising,
breaking the code.

I've updated https://www.emacswiki.org/emacs/GuileEmacsBuild to note this.
You can work around with -fno-builtin-malloc or simply compile with clang
(my current solution).

Emacs trunk has fixed this (in 4b1436b702d56eedd27a0777fc7232cdfb7ac4f6
IIUC), but I believe that commit does not exist in the guile-emacs fork.

Hello,

I can confirm this, but currently have no ideas what is going on
here. This definitely used to work, but gcc was updated since then.

Sorry for inconveniance. I will try to dig deeper into it.

Re: Building Guilemacs

[Wilfred Hughes]

I've had a play with the AUR packages too. The guile4emacs PKGBUILD works
perfectly, but the guile-emacs build process segfaults when bootstrap-emacs
attempts to load calendar/cal-loaddefs.el:

make[2]: Leaving directory

if test "yes" = "yes"; then \
  rm -f bootstrap-emacs; \

else \
  ./temacs --batch --load loadup bootstrap || exit 1; \
  test "X" = X ||  -zex emacs; \
  mv -f emacs bootstrap-emacs; \
fi
make -C ../lisp autoloads EMACS="../src/bootstrap-emacs"
make[2]: Entering directory

Any suggestions?

I wanted to build them in my home directory. I already have Guile installed
and I didn't want to get things confused.

Oh, that's really useful, thanks. I'll have a look at those for
reference (and I've documented them on the GuileEmacsBuild wiki
build).

Excellent!  Happy to hear of your interest.

wip-bpt-elisp has commits from years ago; wip-elisp is rebased on top of
relatively-recent master, with updated ChangeLog.  This was based on the
recent work of robin's from
http://git.savannah.gnu.org/cgit/guile.git/log/?h=wip-elisp

So, you want wip-elisp in origin.  That's the most up to date.

Building Guilemacs

[Wilfred Hughes]

Hi folks

I fancied exploring Guile with Emacs, so I've been trying to build Guile
and Emacs as documented in https://www.emacswiki.org/emacs/GuileEmacsBuild .

I've successfully built the wip-elisp branch of the main guile repo. The
wiki page discusses http://git.hcoop.net/?p=bpt/guile.git and
http://git.savannah.gnu.org/cgit/guile.git/log/?h=wip-elisp . I understand
that the latter is a rebase of the hcoop commits on Guile 2.1.

However, I've also noticed there's a wip-bpt-elisp branch in the main guile
repo. This has the newest commits, but it seems to based on an older guile
version.

Which branch should I use?

I've also failed to compile the Emacs branch that uses Guile. I'm getting
the error:

gcc -c  -Demacs  -I. -I. -I../lib -I./../lib  [many includes elided...]
-I/usr/local/include/guile/2.2   -g3 -O2  vm-limit.c
In file included from vm-limit.c:21:0:
lisp.h:33:22: fatal error: libguile.h: No such file or directory
 #include 
  ^
compilation terminated.

This rather looks like I've screwed up with autoconf somehow. I've set the
environment variables suggested by the wiki page:

ACLOCAL_PATH=/home/wilfred/guile-emacs/guile/share/aclocal
PKG_CONFIG_PATH=/home/wilfred/guile-emacs/guile/lib/pkgconfig
LD_RUN_PATH=/home/wilfred/guile-emacs/guile/lib

so am I missing something?

Thanks
Wilfred
