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:

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@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.

Same question for Vishakh Kumar.

Hi Maxime,

$1 = "x86_64-linux"

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

altomcat@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@guix ~$ emacs -Q

(process:1314): Gtk-WARNING **: 08:41:29.223: Locale not supported by C library.

Using the fallback 'C' locale.

Thanks,

Arnaud

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.
