Description Pacho Ramos gentoo-dev 2012-03-30 08:07:59 UTC 
This causes issues like bug 410149, but also affects to native systems:

$ equery b /usr/lib64/libcairo-gobject.so.2.11000.2
 * Searching for /usr/lib64/libcairo-gobject.so.2.11000.2 ... 
x11-libs/cairo-1.10.2-r1 (/usr/lib64/libcairo-gobject.so.2.11000.2)


Reproducible: Always

Adding mesa to DEPEND would cause circular dependencies.
Comment 2 Chí-Thanh Christopher Nguyễn gentoo-dev 2012-03-30 11:28:25 UTC 
No wait, disregard the above.

media-libs/mesa[egl] could be added for backends that trigger need_egl_functions.

So we need to figure out which ones those are. Then I will apply it to cairo-1.12.2-r2
Comment 4 Ben de Groot (RETIRED) gentoo-dev 2012-07-25 08:44:42 UTC 
Hopefully fixed in cairo-1.10.2-r3 and cairo-1.12.2-r2. Please reopen if this reappears.
Comment 5 Maxim Kammerer 2012-11-21 11:49:18 UTC 
Hi, if cairo depends on EGL automagically, shouldn't a proper fix be to cairo build-time configuration code, and not hardcoding the dependency?

Yes.
Comment 7 Maxim Kammerer 2013-08-24 14:27:45 UTC 
Why not use

  --enable-egl=[no/auto/yes]
                          Enable cairo's EGL functions feature [default=auto]
  --enable-glx=[no/auto/yes]
                          Enable cairo's GLX functions feature [default=auto]
  --enable-wgl=[no/auto/yes]
                          Enable cairo's WGL functions feature [default=auto]
