gd.sl / php and libpng

[Lutz_4]

Hello,

As many ITs I'm triing to use the gd.sl extensions within php.
So I updated the php.ini
Installed the depot requested
Download the 1.0.18 libpng and compiled it via gcc
and now by restarting apache I got the following error :
PHP Warning : Unkown(): Unable to load dynamic library '/opt/hpws/apache/php/lib/php/extensions/gd.sl' -Bad magic number for shared library: /usr/local/lib/libpng.sl.2 in Unknown on line 0
Can somebody help ?

thanks

Looks like the library version is not matching with OS version. If you have OS version 11i, you should be getting library gd.sl for 11i

I've take gd-2.0.33-sd.11.11.depot from HP and apache is 2.054 ...
so the version seems to be ok ...
