Title: pavucontrol.tcz requires libGLESv2.tcz on its .dep file.
Post by: tcFan on June 22, 2017, 03:32:30 PM

Apparently none of its deps require it either.

Loading manually (or adding it to the .dep of course) solves the issue.

Cheers.

I couldn't help but wonder why an audio control app would need an OpenGL library..? 

so..

Code: [Select]

/usr/local/lib $ ldd libGLESv2.so
        linux-gate.so.1 (0xb771c000)
        libdrm.so.2 => /usr/local/lib/libdrm.so.2 (0xb76fc000)
        libm.so.6 => /lib/libm.so.6 (0xb76c1000)
        libdl.so.2 => /lib/libdl.so.2 (0xb76bd000)
        libglapi.so.0 => /usr/local/lib/libglapi.so.0 (0xb76a2000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb768a000)
        libc.so.6 => /lib/libc.so.6 (0xb7575000)
        /lib/ld-linux.so.2 (0x800b6000)
/usr/local/lib $
I don't see any dependency on libGLESv2??

What gives you this impression?

Hi coreplayer2
Running  ldd  on  libGLESv2.so  won't return a dependency on  libGLESv2.so. Maybe you meant:

Code: [Select]

ldd /usr/local/bin/pavucontrol

LOL   yes, what was I thinking??

Code: [Select]

ldd /usr/local/bin/pavucontrol | grep libGLESv2

I'm still curious why OpenGL would be required..

However in TC-8 ldd reports libGLESv2 is required, whilst in TC-7 (where I was looking.) it is not.

All I know is that it complained and failed to start.

I could speculate and say it may be for some graphics function, which is still weird as they should use gtk3 for everything? No idea. lol : -)

libGLESv2 is in the tree file for pavucontrol - I would guess that your version of cairo or cairo's dep file needs updating?

It's not out of the realm of possibility that I tested this before I updated everything, yes.. ^.^

I'm also thinking a dep file needs updating or a dependency extension which would eventually lead to libGLESv2 has not loaded, because in tc-8 cairo was built against libGLESv2.

For what it's worth:
In 7.x/x86 repo:
 libcairo.so was not built against libGLESv2  (libGLESv2 is optional) as a result pavucontrol does not require libGLESv2

However, in these repo's
7.x/x86_64
8.x/x86_64
8.x/x86

libcairo.so was compiled with libGLESv2 support.

If you follow the dep tree either pavucontrol or pulseaudio lists:
 gtkmm/gtk3
  pango
   cairo
    libGLESv2
as dependencies
