Hi,

I have just moved a large webapplication from one server to another. The new server is openSUSE 11.
Everything's gone perfectly, except for a custom program that's run from php using shell_exec().

The program relies on GD to compare images. When the php page runs, I get the following PHP error:

error while loading shared libraries: libgd.so: cannot open shared object file: No such file or directory

A bit of Googling later, and it seems to be a path issue, that the program cannot find libgd.so. However, when I install GD and add the path, I am only given libgd.so.2 in /usr/lib - the error is definitely about libgd.so.

The program is compiled, and I don't have the source. Am I to believe that it's compiled against an older version of libgd? Or am I barking up the wrong tree?

I can rename libgd.so.2 to libgd.so and that suppresses that particular message, but then I get more errors - and I think that's a path I shouldn't really be going down!

Any help would be greatly appreciated.

Thanks,

David

Have you installed the gd-devel package? It contains /usr/lib/libgd.so.

I've installed it now - and it's certainly removed the 'not found error'. However, now in my error_log, I see this:

/srv/www/cgi-bin/compareshell: /usr/lib/libstdc++.so.5: version `CXXABI_1.2' not found (required by /srv/www/cgi-bin/compareshell)
/srv/www/cgi-bin/compareshell: /usr/lib/libstdc++.so.5: version `GLIBCPP_3.2' not found (required by /srv/www/cgi-bin/compareshell)

Are there more packages I'm missing?

Have you compat-libstdc++ installed?

Ah, that's perfect, thanks for your help

Is there a way to find these things out, or is it just a mix of Google and 'pick it up as you go along'?

Just a matter of experience. But when you have an issue with some missing file, you can query which package provides that file (among all the packages provided by all the defined repositories). To do this you can use zypper from the command line, for example:
where the wp command of zypper stats for what-provides.
