Openresty and Imagemagick error: loop or previous error loading module 'magick'

[Porfus]

I use Openresty 1.4.3.3 and want to use Imagemagick library using magick from Lefao. Settings are made from the description http://leafo.net/posts/creating_an_image_server.html.

In this configuration:

location @image_server_test

        {

                default_type text/html;

                content_by_lua '

                        ngx.say("test") 

                        local magick = require "magick"

                ';

}

location ~ ^/imaget/(?<sig>[^/]+)/(?<filename>.*)/(?<pagenumber>.*)/(?<width>[^/]+)$

        {

              root /var/data/image_cache;

              try_files /test.png @image_server_test;

        }

In  nginx logs get the error:

2013/12/10 04:10:09 [error] 5455#0: *83 lua entry thread aborted: runtime error: [string "content_by_lua"]:3: loop or previous error loading module 'magick'

stack traceback:

coroutine 0:

        [C]: in function 'require'

        [string "content_by_lua"]:3: in function <[string "content_by_lua"]:1>, client: 192.168.100.1, server: , request: "GET /imaget/725379571b2fd8fa3ab993b155839c1f/411a66c81a0edbe3ea5bb383ff4caf64/1/800 HTTP/1.1", host: "192.168.100.132"

What could be wrong?

I don't know why you can't see the error message within OpenResty but here's how you can debug it:

magick requires luajit so make sure you've built OpenResty with the flag --with-luajit

If the issue still persists then you can try loading the module outside of OpenResty, if you installed it in the default place you can run:

$ /usr/local/openresty/luajit/bin/luajit

> require "magick"

I tried and got the error:

>  require "magick"

sh: 1: MagickWand-config: not found

It means it can't find the shared library magickwand, which is part of imagemagick. First make sure you have imagemagick installed (and the dev version if your distro does that). I've seen some distributions put magickwand in a separate package so look for a magickwand (or magcikwand-dev) package to install if it still doesn't work

If you get it working tell me what you needed to do and I'll update the readme.

Thanks (and sorry for hijacking the OpenResty mailing list)

I installed the package libmagickwand-dev, now getting another error:

I found what was the problem! 

I used require "magick" and you had the require ("magick").

I badly know lua so I can't tell the difference between these records, but it works.
