php freebsd php5 gd

Solution 1

Before updating always read

/usr/ports/UPDATING

Sometimes you'll need to do recursive portupgrade i.e.

portupgrade -fr png-1.2.37

Solution 2

This is very older bug in freebsd.

In extensions.ini the string extension=gd.so needs to be the first line.

Solution 3

This command solve my problem:

portupgrade -fr png-1.2.40

Solution 4

If you are using portmaster, this will work:

portmaster -dbrR png-1.2.40

I have a problem with my FreeBSD 7.1 server. PHP's GD implementation no longer works on PNG images. Whenever the system tries to work with PNG images, I get these three error messages:

[Sat Jul 18 21:41:15 2009] [error] [client 90.34.34.34] PHP Warning:  imagecreatefrompng() [function.imagecreatefrompng]: gd-png:  fatal libpng error: [00][00][00][00]: unknown critical chunk in /usr/storage/www/private/mikkel.hoegh.org/modules/acquia/imageapi/imageapi_gd.module on line 44, referer: http://mikkel.hoegh.org/admin/build/imagecache/3

I've been trying to solve this half a day now, and the best clue I've found is another guy having the same problem – no solution there, though.

The code in question is fairly simple, it just calls imagecreatefrompng($filename);

Package versions of all the packages I can think of that might be related:

php5-5.2.10
php5-gd-5.2.10
png-1.2.37
gd-2.0.35_1,1

Any clues?

Well, it is the same with all PNG images I've tried. And as far as I can see, the error message is exactly the same whether you output it to the log or to the screen.

Yeah, I already tried to rebuild php-gd with all of its dependencies. I think I might try something more… drastic. I have an upgrade to 7.2 I've been putting off for a while, so if I have to rebuild all my packages, that might be a good occation :)

The versions I mentioned are the latest available – I have tried the upgrade strategy already…

Okay, interesting – I've managed to get my image processing working by using imagemagic (the CLI util, not the pecl package). That could indicate that this might in fact be a PHP bug. shakes tiny fist at PHP

Was there anything in particular I should have noticed in UPDATING? I can't spot something related to this problem. I don't use portupgrade, but I'm running a sudo portmaster -ru graphics/png now to see if that'll fix it.

Recursive rebuild did not fix the problem, sadly. I tried earlier by rebuilding all dependencies of php5-gd, but that had no effect either.

maybe, as last resort, portmaster -fa will help?

Thankfully, it has disappeared after I upgraded to FreeBSD 7.2. I think the decisive change was the complete rebuild of all packages. Thanks.
