Re: Couldn't link my app with GTK+ 3

[Jaroslav ÅmÃd <jardasmid gmail com>]

export PKG_CONFIG_PATH=/usr/lib/pkgconfig/
./configure

pkg-config used in confugure script will use glib-2.0.pc from that 
location. PKG_CONFIG_PATH should point to your new glib's 
${libdir}/pkgconfig/

Your old glib doesn't seem to have functions/symbols used in gtk-3 and 
you will need to use the new one.

Note that by installing with prefix=/usr, you overwrote old headers with 
new ones, but you installed libraries next to old ones. Looks like you 
should've used something like
./configure --prefix=/usr --libdir=/usr/lib64
as you seem to have multilib system. This will make old apps to use new 
glib, but that should be OK as only new api is added.
