virt-manager fails to load shared library on Big Sur

[idryzhov (Igor Ryzhov)]

$ virt-manager
** (process:12757): WARNING **: 16:03:26.872: Failed to load shared library 'libgdk_pixbuf-2.0.0.dylib' referenced by the typelib: dlopen(libgdk_pixbuf-2.0.0.dylib, 9): image not found
: Could not open display: :0

Looks like a problem in gobject-introspection, because gdk-pixbuf has relative paths in gir files:

$ grep libgdk /opt/local/share/gir-1.0/* -r
/opt/local/share/gir-1.0/Gdk-2.0.gir:             shared-library="/opt/local/lib/libgdk-quartz-2.0.0.dylib"
/opt/local/share/gir-1.0/Gdk-3.0.gir:             shared-library="/opt/local/lib/libgdk-3.0.dylib"
/opt/local/share/gir-1.0/GdkPixbuf-2.0.gir:             shared-library="libgdk_pixbuf-2.0.0.dylib" <-- relative path
/opt/local/share/gir-1.0/GdkPixdata-2.0.gir:             shared-library="libgdk_pixbuf-2.0.0.dylib" <-- relative path

Same impact for the Deluge port:

WARNING **: 15:43:20.653: Failed to load shared library 'libgdk_pixbuf-2.0.0.dylib' referenced by the typelib: dlopen(libgdk_pixbuf-2.0.0.dylib, 9): image not found

/opt/local/share/gir-1.0/Gdk-2.0.gir:             shared-library="/opt/local/lib/libgdk-x11-2.0.0.dylib"
/opt/local/share/gir-1.0/Gdk-3.0.gir:             shared-library="/opt/local/lib/libgdk-3.0.dylib"
/opt/local/share/gir-1.0/GdkPixbuf-2.0.gir:             shared-library="libgdk_pixbuf-2.0.0.dylib"
/opt/local/share/gir-1.0/GdkPixdata-2.0.gir:             shared-library="libgdk_pixbuf-2.0.0.dylib"

I found I could work around the problem by setting LD_LIBRARY_PATH explicitly:

LD_LIBRARY_PATH=/opt/local/lib deluge

The same issue exists on Mac OS Mojave 10.14.6, after port upgrade outdated

Here the log after launching virt-manager:

(process:17807): WARNING : 10:08:42.575: Failed to load shared library 'libgdk_pixbuf-2.0.0.dylib' referenced by the typelib: dlopen(libgdk_pixbuf-2.0.0.dylib, 9): image not found : Could not open display: /private/tmp/com.apple.launchd.QLKXO4qYtE/org.macports:0

And here the log after trying to reinstall the package:

---> Configuring virt-manager Error: Failed to configure virt-manager: gtksourceview4 must be installed with +x11 and without +quartz. Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_gnome_virt-manager/virt-manager/main.log for details.

Nicholas Sherlock, I'm not able to workaround the issue exporting the LD_LIBRARY_PATH variable... :-(

After updating the ports tree you need to force the rebuild (they need to revdump the ports):

sudo port -sn upgrade --force gobject-introspection gdk-pixbuf2

Then it should work fine.

[netdesign (Netdesign)]

Ra1nb0w, I executed that command but virt-manager refuses to install:

Error: Failed to configure virt-manager: gtksourceview4 must be installed with +x11 and without +quartz.
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_gnome_virt-manager/virt-manager/main.log for details.

Error: Processing of port virt-manager failed

[ra1nb0w]

This is another error. Probably you have choose quartz as default (/opt/local/etc/macports/variants.conf) but gtksourceview4 wants x11.

[netdesign (Netdesign)]

I have this:

sh-3.2# cat /opt/local/etc/macports/variants.conf

# MacPorts system-wide global variants configuration file.

+x11

But still the same error:

--->  Configuring virt-manager
Error: Failed to configure virt-manager: gtksourceview4 must be installed with +x11 and without +quartz.
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_gnome_virt-manager/virt-manager/main.log for details.

[ra1nb0w]

There is something that force quartz variant and virt-manager with x11 variant or vice-versa. gtksourceview4 and virt-manager seems that they work fine if used with quartz. Maybe try to sudo port reclaim and recheck if you have some mismatch already built (started with quartz and now try to build with x11).

I had the same problem on Mojave 10.14.6, but with variant +quartz. The suggestion in comment:9 solved it for me.

Update: As the window for the VM did not work, and then also the VNC console had an error, I also had to rebuild this two ports:

sudo port -sn upgrade --force gtksourceview4 gtk-vnc
