Updating also seems to break existing installs of mod_php upon restart... I get unresolved symbols in createImageFromGif when starting mod_php now :(
-gdFreeFontCache () +gdFontCacheShutdown () seems the name was changed between 2.0.15 and 2.0.17 simply changing the func name in ext/gd/gd.c when gd-external is in USE and gd-2.0.17 is present is sufficient to fix this bug
the GIF support was removed from libgd in the 2.0.17 release. this is the cause for the createImageFromGif() problem on restart.
It's also worth noting that the PHP Group recommend that you use the version of libgd that is bundled with PHP, rather than the external libgd distribution. This recommendation has been the case since PHP 4.3.0. I'd recommend fixing this by restricting which versions of libgb the php ebuilds depend on. Stu
it is controlled via gd-external USE flag ... i think doing anything beyond that is placing too much control over the user
also, the reason gif support was 'removed' in 2.0.17 is because the people who write the gif patch havent updated it to 2.0.17 yet i should have a 2.0.17-r1 in the tree soon that has gif supported 'added' back in (ported the patch myself) this should be added to the php.eclass though (or something similar): if has_version '>=media-libs/libgd-2.0.17' \ && sed -i 's:gdFreeFontCache:gdFontCacheShutdown:' ${S}/ext/gd/gd.c
Shrugs. I'm not exactly crazy about patching PHP just to support an alternative (and notoriously buggy) version of the gd library - even if the patch is trivial. But there again, it's not my shout ;-) Stu
I'm closing this as I warned the person that originally wanted gd-external capabilities that it may break due to upstream issues at various times, and the only method i was now officially supporting is the one included with the PHP sources. The sole reason behind this is the in-ordinate amount of work that an external gd has required in the past, and it just isn't worth it to do it myself (but patches definetly accepted if somebody else wants it). I've put Vapier's sed fix in place for now.
i'm the one who created gd-external and then broke your php setup oh-so-long-ago ;) thanks
