Hi, I need to install imagemagick & perl magick on a linux server where I don't have root.

I grabbed the source & compiled to install imagemagick & perl magick in my home dir, configured like this:

Code: Select all

./configure --prefix=/home/me/lib/imagemagick --with-perl-options=PREFIX=/home/me/lib/perl

The install seemed to go fine (install report below) & I was able to run the imagemagick utils from the shell.

However, perl magick did not work. When use Image::Magick ; was invoked in a perl script, it would crash, complaining

Code: Select all

Can't load '/home/me/lib/perl/lib/perl5/site_perl/5.8.7//x86_64-linux/auto/Image/Magick/Magick.so' for module Image::Magick: libMagick.so.10: cannot open shared object file: No such file or directory at /usr/lib/perl5/5.8.7/x86_64-linux/DynaLoader.pm line 230.
 at test.pl line 8

(incidentally the crashes are very nasty, running on & on & eating up all the memory... if run via the web server it can actually crash the server.

I ran ldd on Magick.so and found it did not know where libMagick.so.10 was located (its actually in /home/me/lib/imagemagick/lib).

When I set the environmental variable LD_LIBRARY_PATH to point to the directory where libMagick.so.10 resides, Magick.so can find it, & perlmagick is able to run.

However, this is not possible to do within the perl program itself (I have tried, but it doesn't work and apparently can't, at least according to reasearch I did--see http://www.thescripts.com/forum/thread49850.html ). This is bad, because now I can't get my web-based programs to work.

So my questions are:
1) shouldn't Magick.so already know where the libMagick.so.10 file is, since they were both installed from the same source durring the same compile? Why does Magick.so need to have LD_LIBRARY_PATH at all?

2) How can I get imagemagick & perlmagick to work properly without having to rely in that environmental variable.... because if I need that variable, I can't run it from the web server, which will make all my web apps that want to use perl magick useless.

3) I don't completely understand the little report I got when configuring Image Magick but it seems to say that the /home/me/lib/imagemagick/lib directory whould already be in the LD PATH (see LDFLAGS below)

I know this should work, I have done it before on other servers but I am flummoxed now.

Perhaps I need to recompile with different options? I would like to avoid recompiling perl if possible.

Please help me with your wisdom.

This is the configuration report from when I installed Image Magick:

I am getting the same problem

Can't load '/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/Image/Magick/Magick.so' for module Image::Magick: libMagick.so.10: cannot open shared object file: No such file or directory at /usr/lib/perl5/5.8.8/i386-linux-thread-multi/DynaLoader.pm line 230.

any response would be helpfull

You may need to add the location of your ImageMagick library to your load library path. Something like

ldconfig /usr/local/lib

Thanks, thats worked for me!

There does not seem to be an ldconfig command on my system, and in any case wouldn't I need to have root access?

Isn't there some other way to tell Magick.so where to find its libraries? It seems to me that it should know by itself, given that it was created by the same compile that created those librarys & imagemagick itself.

You can also add to the build a something like

Code: Select all

LDFLAGS="-R/path/to/IM/library/install/dir"

that will on most UNIXy systems build the library path into the .so file.

How to add it to the build is another matter. Often this type of thing is handled by 'libtool' lookups of '.la' files.

But since LDFLAGS already seems to include the imagemagick directory (see my original post above), shouldn't it already work? Or am I misunderstanding something?

It should. the -L is for compile time location of the library, -R is for runtime path to look for library. The --rpath I think converts -L into -R equivelents.

OK, I did a make uninstall" and "make distclean" and reconfigured & remade with:

Code: Select all

./configure LDFLAGS=-Wl,-rpath,/home/me/lib/imagemagick/lib --prefix=/home/me/lib/imagemagick/ --with-perl-options=PREFIX=/home/me/lib/perl/

The configure output at the end was the same as above, except:

Code: Select all

  LDFLAGS     = -L/home/northroa/lib/imagemagick//lib -Wl,-rpath,/home/northroa/lib/imagemagick/lib -L/usr/lib64 -Wl,--rpath -Wl,/usr/lib64 -lfreetype -lz -L/usr/lib

The result is the same, though...the new Magick.so file still does not find the libMagick.so.10 file unless the LD_LIBRARY_PATH is set in the envrionment, same as before... so I still can't use perlmagick through the webserver.

Did I set up the ./configure correctly?

Anybody have any ideas on how I should proceed? I would really like to get imagemagik working, but I'm really perplexed right now...any help would be appreciated!

Quite a predicament you found yourself in. LD_LIBRARY_PATH cannot be used. And I believe ldconfig will not accept a path not owned by root.

An ugly way (which I just recommended against in another, similar thread, lol,) is to use a symlink. Figure out what lib dirs ARE reachable from within the webserver (like ~/me/usr/lib perhaps?) and create a symlink from there to the location of libMagick.so.10. Not pretty, but it might tide you over.

Hi Mark, thanks for the reply.

Do you know how I can determine which directorys are "reachable" by Magic.so, though? If I don't know that I don't know where to put the link.

Also, I fear that it may only be directorys that I have no write access to that will be reachable.

First things first, how is your Perl set up exactly? As a localized version? Cuz it seems you're running a system wide one with a local module path somehow.

Ok where is Image::Magick located? You could use that path, like:

use lib '/home/me/lib/perl/lib/perl5/site_perl/5.8.7/ImageMagick';
use Image::Magick;

I doubt this will really work, though. But you can always give it a try.

Hi Mark,

I'm using the system wide perl, and yes, I use a 'use lib' statement like you indicated. However, the probelm isn't that perl can't find the Image::Magick module or that Image::Magick can't find Magick.so; the probelm is that Magick.so can't find libMagick.so.10. And I can't link libMagick.so.10 into a directory that Magick.so knows about because I don't know what directories Magick.so dynamically loads librarys from. I suspect that even if I did know it wouldn't help because I probably can't write to those directories.

Shouldn't it be possbile to create a Magick.so file that knows where libMagick.so.10 is located?
