If desired, apply the optional patch. In many cases, applications that
|
|
use this library, either directly or indirectly via other libraries such
|
|
as <xref linkend="gtk3"/>, output numerous warnings when run from the
|
|
command line. This patch enables the use of an environment variable,
|
|
<envar>GLIB_LOG_LEVEL</envar>, that supresses unwanted messages. The
|
|
value of the variable is a digit that corresponds to:

If upgrading from a previous version of GLib that was built using
|
|
autotools, and the <application>libtool</application> archives (.la
|
|
files) were installed, you will need to adjust all installed libtool
|
|
archives,
|
|
<filename>/usr/lib/libg{io,lib,module,object,thread}-2.0.la</filename>,
|
|
to replace references to the libtool archives for this package with the
|
|
appropriate linker library flag (-l),
|
|
<command>-lg{io,lib,module,object,thread}</command>. 600+ files must be
|
|
modified on a complete gnome desktop.

Alternatively, you can just remove the unneeded .la files

with the script at <xref linkend="la-files"/>.

One test named gdbus-server-auth sometimes fails.

the link must be to some place like /usr/share/zoneinfo/...
