librsvg.tcz update bug?

[thane]

I'm a little hesitant to report this as a bug, since it may have been an issue with my own setup and I was able to resolve it. Just in case though:

After installing the 11/13/2025 update to librsvg.tcz (TCL 16.2 x86_64) on a lenovo X201 Thinkpad, when I rebooted the desktop was almost unreadable and the Evince app wouldn't start. Luckily I was booting off USB, and was able to boot off the same USB to a readable desktop on another computer. Attempting to start Evince from a terminal showed missing libraries, which according to Apps are provided by extensions that I already had. Based on the Apps info I manually added libEGL.tcz and libGLESv2.tcz to onboot.lst. This resolved the missing libraries issue, and the desktop problem on the Thinkpad.

Like I said, this may just have been a weird issue with my rather dated hardware. Hopefully nobody else has problems!

Hi thane
The dependency chain for librsvg appears to have changed.
librsvg depends on pango depends on cairo which used to depend on libEGL and libGLESv2.

Hi thane
It appears this has come up before:

[thane]

Hi Rich, libEGL.tcz and libGLESv2.tcz show up in my Apps "All not depended on" list. Maybe I need to update .dep files?

[GNUser]

Hi, thane. I always update with the command update-everything, which gracefully handles changed .dep files and missing dependencies. Please try running that command and see if it solves your problem.

[thane]

Thanks, I'll try that.

Hi thane
I just ran a scan on my 64 bit TC16 install and these were the extensions
that were dependent on libEGL.so (including libgbm.so) or libGLESv2.so:

These are the extensions that list libEGL.tcz or libGLESv2.tcz as dependecies:

Code: [Select]

tc@box:~$ grep -E "libEGL|libGLES" /etc/sysconfig/tcedir/optional/*.dep
/etc/sysconfig/tcedir/optional/Xorg-7.7-3d.tcz.dep:libEGL.tcz

Thanks Rich. My Apps lists both libEGL.tcz and libGLESv2.tcz as not required by any other extensions, but it appears that evince.tcz and the desktop on my Thinkpad do need those extensions (or at least libraries from them) to function. I'll check my setup for the extensions you list. I'll also do the update that GNUser suggested. It could be something in my setup is out-of-date.

Hi thane

... it appears that evince.tcz and the desktop on my Thinkpad do need those extensions (or at least libraries from them) to function. ...

Or their dependencies need them.
The previous command I posted relies on the  .so  link to libraries to be present.
Extensions that should not be linked against have them stripped out, leaving
only  .so.digit(s) , .so.digit(s).digit(s) , .so.digit(s).digit(s).digit(s). To further
complicate things, some extensions have only  .so  files with no version
numbers, like  mesa/usr/local/lib/dri/i915_dri.so.

This command filters out  .so.digit(s).digit(s) , .so.digit(s).digit(s).digit(s)  to
reduce output from the same libraries but allows  .so , .so.digit(s)  to be
processed by  readelf. I also had to escape the periods for grep:

Code: [Select]

for F in `find /tmp/tcloop/ | grep -vE "\.so\.[0-9]+\.[0-9]+$|\.so\.[0-9]+\.[0-9]+\.[0-9]+$"`; do readelf -d $F 2> /dev/null | grep '(NEEDED)' | grep -oE "libEGL|libGLES|libgbm" && echo $F; done
It will identify the dependency, executable, and extension.

libgbm (provided by libEGL.tcz) is required by crocus_dri.so which is in mesa.tcz:

Code: [Select]

libgbm
/tmp/tcloop/mesa/usr/local/lib/dri/crocus_dri.so
libEGL and libGLES are required by libcanberra-gtk-module.so which is in libcanberra.tcz:

Code: [Select]

libEGL
libGLES
/tmp/tcloop/libcanberra/usr/local/lib/gtk-2.0/modules/libcanberra-gtk-module.so
If you run this command on your machine, you can identify which extensions
actually depend on libEGL.tcz and/or libGLES.tcz.

Depending on the speed of your machine, this command may take a couple of minutes.

It's not obvious that evince is pulling in libEGL/GL/GLESv2 (I could be wrong).

What xserver and what desktop are you using?

Hi Juanito
Find which programs/libs on my machine depend on libEGL:

Code: [Select]

tc@box:~$ for F in `find /tmp/tcloop/ | grep -vE "\.so\.[0-9]+\.[0-9]+$|\.so\.[0-9]+\.[0-9]+\.[0-9]+$"`; do readelf -d $F 2> /dev/null | grep '(NEEDED)' | grep -qE "libEGL|libgbm" && echo $F >> EglDeps.txt; doneFind which programs/libs on my machine depend on libGLESv2:

Code: [Select]

tc@box:~$ for F in `find /tmp/tcloop/ | grep -vE "\.so\.[0-9]+\.[0-9]+$|\.so\.[0-9]+\.[0-9]+\.[0-9]+$"`; do readelf -d $F 2> /dev/null | grep '(NEEDED)' | grep -qE "libGLESv2" && echo $F >> Glesv2Deps.txt; done

xorg-serverevince depends on  gst-plugins-base  but its .dep file does not include libEGL.
libEGL popped up because libEGL.so depends on libgbm.so which is part of libEGL.

I'm using Xorg-7.7 (xorg-server). Desktop is flwm_topside.
