bug#64981: GTK4 applications broken (missing libGLESv2)

[Csepp]

for example:
$ transmission-gtk
Couldn't open libGLESv2.so.2: libGLESv2.so.2

I get the same error with Tuba.  It likely affects other applications.

I assume you are not using the gnome-desktop-service, are you?

Neither transmission-gtk nor GTK4 appears to actually link against
libGLES, so there's probably something arcane going on already.  Have
you tried the usual debugging tools (GDB, strace)?

Cheers

Yup, I'm using Sway without a display manager.  Gnome was a memory hog.

Not yet, but I did now:

```
$ strace -e %file transmission-gtk |& grep libGL                                                :(
openat(AT_FDCWD, "/gnu/store/gsjczqir1wbz8p770zndrpw4rnppmxi3-glibc-2.35/lib/libGLX.so.1", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

openat(AT_FDCWD, "/gnu/store/gsjczqir1wbz8p770zndrpw4rnppmxi3-glibc-2.35/lib/libGLESv2.so.2", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

Couldn't open libGLESv2.so.2: libGLESv2.so.2: cannot open shared object file: No such file or directory
```

So it's not looking for it in Mesa, which is odd, isn't that where it's
supposed to be?  According to guix locate libGLESv2.so.2, it should be
in one of the Mesa packages.

Thanks for helping me look into this!  Gonna look a bit more into what's
going on...

Oddly, GTK 4 apps work fine for me on Sway.

Hi,

I've the same issue for several programs.

I'm using sway and I tried to use dino.

I've built dino like that:
> guix install dino \
> 	--with-debug-info=gtk \
> 	--with-debug-info=glib \

> chmod +x dino

And here's my gdbinit:

Then I run ./dino and I get that:

So for some reasons it fails in libepoxy.

So I tried to reproduce the issue:

All the above is in Guix system.

The libGLESv2.so.2 comes from libglvnd, but libglvnd is not a
dependency of dino, and I only installed libglvnd with 'guix
package -i libglvnd' and dino is wrapped, so maybe for some reason
it doesn't find libglvnd.

I've tried to add libglvnd in dino inputs, but I got the same error
message (I didn't look at it with gdb though).

But if I install dino with Guix on top of parabola (a host
distribution) then it works fine.

I've also found out that gnome-weather was also complaining about a
missing libGLESv2:
> $ gnome-weather 
> Couldn't open libGLESv2.so.2: libGLESv2.so.2: cannot open shared object file: No such file or directory
> Aborted
but I didn't try to debug that.

Probably many more applications (than dino and gnome-weather) are
broken on Guix system.

I've been getting this too, I'm "glad" to see I'm not the only one.  If
I set GSK_RENDERER=cairo (the fallback renderer) then I can launch gtk4
applications.

I am also running into this issue. Efraim's suggestion with changing the GSK_RENDERER
to cairo seems to work for me.  I'm on a Thinkpad T400.

Hello, since we already hardcode paths for libGL, adding libGLES seems
reasonable.

Have test it though, because on my machine (kwin in wayland) it seems
GTK4 applications will use GL renderer instead of GLES.

Hi everyone,

Not sure if people saw this patch, has anyone tested if it fixes the
problem for them? I can include it in an upcoming mesa-updates branch
with other related updates/rebuilds.

<https://issues.guix.gnu.org/65375>

Hope I got everyone from the original bug thread (seems many replies
didn't go directly to everyone) and cc'ed the patch number as well.

Thanks!
John

Pushed as 37fc2c99e0067dfd669526c61dc10d014b89c08b (on mesa-updates
first and then merged to master).

Thanks!
