Unable to load dynamic library '/usr/lib/php4/20050606/gd.so

[sYs^]

Hi,

I'd like to enable GD support on my server, I use Apache/2.0.55 (Debian) PHP/4.4.2-1+b1 mod_ssl/2.0.55 OpenSSL/0.9.8a. I have gd extension enabled in my php.ini but when I restart my apache it writes this to the error.log:

Code: Select all

Any ideas? Thank you in anticipation!

Your shared library is not being found because you haven't told Apache where to find it. If you have a read of man ld.so(8), ldconfig(8), you'll see there are a few ways to do this.
You could, for instance, put the library in a standard place. Or you could update your /etc/ld.so.conf adding the directory where your library is and run ldconfig.
Or set LD_LIBRARY_PATH in your Apache's environment.
I'd be inclined to put the library in /usr/local/lib and if necessary do the ld.so.conf thing.
