Bug 315795 – media-libs/libpng-1.2.43 "doesn't have APNG support"

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Richard 2010-04-17 21:01:31 UTC]

I decided to fiddle with Mozilla Firefox by compiling it manually to see if I could get PGO enabled based on system information at Mozilla's bugzilla (https://bugzilla.mozilla.org/show_bug.cgi?id=418866). I used a .mozconfig file that had "--with-system-png" enabled and firefox's ./configure script failed citing:

checking for png_get_acTL in -lpng... no
configure: error: --with-system-png won't work because the system's libpng doesn't have APNG support

There is no use flag to enable APNG support in libpng, so this is a problem because it means that www-client/mozilla-firefox is building with its own libpng library when I believe that Gentoo's policy is to rely on the system libraries as much as possible.

Reproducible: Always

Steps to Reproduce:
1. Get the firefox source code and extract it.
2. Make a .mozconfig file with the following contents:

. $topsrcdir/browser/config/mozconfig
ac_add_options --with-system-png
3. Run the configure script



I am running a ~amd64 system with www-client/mozilla-firefox-3.6.3:
