Subject: Emacs crashes due to symbol lookup error to rsvg_handle_set_stylesheet

Hey fellow Guix users,

I’m trying to use Emacs on my system but it tends to crash unexpectedly. 

When launching it from a terminal, I get:

> grokkingstuff <at> grokkingNoether ~$ emacs
> (process:32402): Gtk-WARNING **: 22:59:14.455: Locale not supported by C library.
> 	Using the fallback 'C' locale.
> /home/grokkingstuff/.guix-profile/bin/emacs: symbol lookup error: /home/grokkingstuff/.guix-profile/bin/emacs: undefined symbol: rsvg_handle_set_stylesheet


Trying to use emacs -q, I get a similar message, but it just crashes quickly.

I have librsvg installed, and a few Google searches seem to indicate that this is the issue. I’ve tried building from source using "guix install -S” but I don’t see any difference.

If there’s anything I could do to assist with this bug report, please let me know. Thank you so much for your time and effort.

Sincerely,
Vishakh Kumar (grokkingstuff)

Looking at this output, it seems Emacs is trying to dynamically link
librsvg.  Two issues spring to mind: First, this kind of linkage is not
that well supported by Guix, so we tend to substitute* the full path. 
Is this done for librsvg?  Second, there might be a (version) mismatch
between the librsvg Emacs expects and the one it gets.  Does
rsvg_handle_set_stylesheet actually exist as a symbol in your librsvg?

Cheers

Hi there,

I'm facing the same issue from a fresh 1.3 installation I did on a VM. 
Emacs28.2 is linked against librsvg-2.40.21 which do not provide rsvg_handle_set_stylesheet function.

altomcat <at> guix ~/.config$ libtree /gnu/store/jpi4h6afvkifypxjxdpgrdm4shnmavwf-emacs-28.2/bin/.emacs-28.2-real | grep rsvg

Emacs runs well if I insert the path of librsvg-2.50.7 to LD_LIBRARY_PATH as follow

export  LD_LIBRARY_PATH=/gnu/store/34yxh2p22yaiisb1ayp43ig06hdlj0wg-librsvg-2.50.7/lib:$LD_LIBRARY_PATH

I checked the package definition with `guix edit emacs`
...
           ;; When looking for libpng `configure' links with `-lpng -lz', so we
           ;; must also provide zlib as an input.
           libpng
           zlib
           (if (target-x86-64?)
               librsvg-bootstrap
               librsvg-2.40) => need to be change ?
           libxpm
           libxml2
...

I'm a newbie and I hope these details can help. I would appreciate a little help to go further and solve this issue.
Thanks.

Which architecture are you on?  You can find out with

$ echo '(use-modules (guix utils)) (%current-system)' | guix repl

Same question for Vishakh Kumar.

Greetings,
Maxime.

Hi Maxime,

$1 = "x86_64-linux"


Running emacs command failed but 'emacs -Q' works. 

altomcat <at> guix ~$ emacs

(process:1306): Gtk-WARNING **: 08:41:25.920: Locale not supported by C library.
	Using the fallback 'C' locale.
/home/altomcat/.guix-profile/bin/emacs: symbol lookup error: /home/altomcat/.guix-profile/bin/emacs: undefined symbol: rsvg_handle_set_stylesheet
altomcat <at> guix ~$ emacs -Q

(process:1314): Gtk-WARNING **: 08:41:29.223: Locale not supported by C library.
	Using the fallback 'C' locale.

Thanks,
Arnaud

Then unless 'grokking Stuff' has a different system, I am not following 
their proposal, because because on x86-64 ...

... the first branch would be taken, so changing the second branch would 
have no effect.  However, perhaps the rsvg_handle_set_stylesheet is only 
present in the 'librsvg', and not in 'librsvg-bootstrap' (I wouldn't 
expect that as they are the same version, but it could be tested).  If 
so, librsvg-for-system could be used instead, at cost of some rebuilds.

Greetings,
Maxime
