help detecting misleading argumetns ofr Convert

Hi, I'm using Ruby's Paperclip gem and I have a very weird error coming from the "convert" command. It seems that paperclip goes nuts somewhere and it may be swallowing some argument when building up the full command line to execute.
So this is what paperclip "says" it is executing, which it
works fine if I copy paste it in my console:
Code: Select all
convert /tmp/stream20120222-16799-h6517r.txt[0]' -resize "90x90^" -unsharp 0x.7 -gravity center -extent 90x90 '/tmp/stream20120222-16799-h6517r20120222-16799-1yalfzi.gif'
But somehow Paperclip is messing up something, and I'm thinking that one thing is what it "says" it is executing and another thing it's what it actually "runs". So when running
inside Paperclip I'm getting this error from "convert":
Code: Select all
convert: invalid argument for option `90x90^': -resize.
What's puzzling me is that "convert" thinks that "90x90^" is the option and "-resize" is the argument of the option. So something is pretty wrong in how Paperclip is building the command. But I can't figure it what!
So what I'm asking here is if somebody could help me out to understand how Paperclip is messing around the arguments for such an error to show up. For example it would be great to know what argument needs to be missing so the error shown pops up
Thanks!

Sorry I know nothing about paperclip.
Just some sanity checks ---
What version of IM are you using? The ^ option was not added until IM IM 6.3.8-2. However it is strange that it works in your terminal but not in your paperclip. Perhaps ^ means something special in paperclip?
try escaping ^ and no quotes and see if that helps
-resize 90x90\^

Thank you very much for your reply
Yeah I tried escaping and removing quotes and seems to works always...

I doubt this is the problem, but perhaps paperclip does not like IM running with OpenMP. You can recompile using --disable-openmp and see if that helps.
Also try without the ^ in the resize and see if that even works.

I was also thinking... I'm in a shared hosting, there is any way that somehow a misleading library is being picked up? I'm asking this because for what I've read the error in question seems to be from an earlier version of ImageMagick right?
So there is any recommended way of compiling it so I can be sure that it is always using the correct version of the libraries?

If there are multiple version of IM in the same location that could be a problem. But it does not explain why you can run it fine from the terminal and not with your other program.
However, the other program could be linked to another and possibly older version of IM.
You can try this in your terminal
type -a convert
or
which convert
The former may be better at telling your multiple versions of IM.
See if you really have multiple versions and where they reside. Then you can preface convert with the full path to the one you want to use presumably the more current one.

So No. I wasn't able to make this work correctly... Neither after setting the correct path of the ImageMagic binaries. I've tried almost everything.
So I ended up "manually" selecting the resize geometry based on the file's current width and height. I took @fmw42's "squareup" script and adapted it to my needs.
Thanks anyway!

You are missing single quotes at the start of the first filename!
EG: convert
'/tmp/stream20120222-16799-h6517r.txt[0]' -resize "90x90^" ....
