[gentoo-user] Re: Headsup: bad breakage from today's xcb update

[godzil <godzil@godzil.net>]

 I have similar breakage with xcb*-0.3.8 but with gnome-base/nautilus 
 this time, but seems related with startup-notification...

 During the ebuild compilation, it fail with a link error searching for 
 libxcb-aux, libxcb-event and libxcb-atom. I search in all .la file, run 
 lafilefixer to verify if all la is fixed

 I found refs about this libs in some .la files inside /usr/lib (here 
 libcheese-gtk.la,  libgksu2.la libgnome-desktop-2.la, 
 libmetacity-private.la and libstartup-notification-1.la)

 It looks like nautilus search for libstartup-notification and the .la 
 file end with screw everything. Maybe lafilefixer should have some logic 
 to search for missing lib inside la file, like revdep-rebuild do on 
 binary files. Searching for such breakages is really a pain, and can 
 happen oftenly with such bad tools as libtool...


 Both xcb and startup-notification are latest version and compile 
 without a problem:

 [I] x11-libs/startup-notification
      Available versions:  0.10 (~)0.10_p20110426 {static-libs}
      Installed versions:  0.10_p20110426(16:40:14 
 04/27/11)(-static-libs)
 [I] x11-libs/xcb-util
      Available versions:  0.3.6 (~)0.3.8 {debug doc static-libs test}
      Installed versions:  0.3.8(10:15:14 04/28/11)(-doc -static-libs 
 -test)

 (of course revdep-rebuild found nothing to do on 
 /usr/lib/libstartup-notification-1.so, so no easy way to find and 
 eliminate such painful bugs.)
