When I was installing the application (libvirt-sandbox-0.1.2) I've got this message:
configure: error: Package requirements (gio-unix-2.0 >= 2.28.0) were not met: No package 'gio-unix-2.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GIO_UNIX_CFLAGS and GIO_UNIX_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
How to install this libraries?
