 |
|
Problem occured on two separate systems, running an uptodate (as of now) system.
PROBLEM DESCRIPTION
----------------------------
When trying to use any of the 'png' functions from the GD library built into the mod_php, apache would return no data to the browser, and a line like:
| Code: | | [Thu Jul 18 14:35:39 2002] [notice] child pid 32045 exit signal Segmentation fault (11) |
would appear in the apache error logs.
After some testing, I narrowed down the problem to be the version of libpng which has been built into PHP / GD.
Version's installed:
mod_php
/usr/portage/dev-php/mod_php/mod_php-4.2.1-r5.ebuild
libgd
/usr/portage/media-libs/libgd/libgd-1.8.3-r5.ebuild
libpng
/usr/portage/media-libs/libpng/libpng-1.2.4.ebuild
TO FIX THE PROBLEM
-------------------------
To 'fix' this problem, I had to:
| Code: | # remove the old libpng
unmerge libpng
# manually emerge the older version
/usr/portage/media-libs/libpng/ebuild libpng-1.0.12-r1.ebuild merge
# re-emerge libgd
emerge libgd
# manually edit the ebuild mod_php file you want to emerge
# in my case, it was this one
nano -w /usr/portage/dev-php/mod_php/mod_php-4.2.1-r5.ebuild
# under the depends, hash out the existing reference to libpng
# and put in the older version which we emerged earlier
# >=media-libs/libpng-1.2.1 <- hash this line
>=media-libs/libpng-1.0.12 <- enter in this one
# re-emerge mod_php, which will use the older libpng to build from
emerge mod_php
# restart apache
/etc/init.d/apache restart |
And that has fixed the problem. I don't know where this bug lies (php, or libgd, or libpng?) but this is a working temporary fix.

Not yet - wasn't sure what sort of bugs are to be posted to bugs.gentoo - so I should?

Yes -- bugs.gentoo.org are for any and all bugs that are gentoo-related.

Can someone tell me how this works? I've tried countless versions of this and when I do an emerge -p mod_php it has a big U next to my libpng package and promlptly tries to upgrade it on me.
I did not find a newer version to hash out so just added the older version under DEPEND but it never sees it |

Hey zapdafish
I'd ignore this now - it was written exactly a year ago, when there was a problem .. All should be fixed up by now.
