Rmagick not handling GIF files properly

Rails
#1

Tracked down the source of my problem…

It seems that Rmagick isn’t properly cropping/resizing GIF or PNG images
when uploaded via file_column. I can upload JPG files just fine.

Originally I had installed ImageMagick via Debian’s apt-get and built
the
rmagick gem using “gem install rmagick”. This wasn’t working so I
uninstalled ImageMagick and tried to compile GraphicsMagick by hand,
then
reinstall the rmagick gem.

This also isn’t working, and it’s driving me nuts. The same code works
perfectly on my OS X dev machine.

Does anyone have pointers to get this working properly? Please help!
Thanks…

#2

have you got the libgif / libpng headers installed?

#3

I think I do - but how do I make sure?

#4

One other thing that might be helpful:

I’m trying to build RMagick from source now, and after running:

./configure --with-graphics-magick
make

I’m getting this…error over and over again (with different rb scripts)

For anyone who cares, got RMagick installed after installing ghostscript

but when I try to upload an image now I get an Application Error page
with
nothing in the apache or rails error log.

I’m going nuts here! Has anyone built RMagick on a debian box FROM
SCRATCH /
SOURCE and have it fully working? Please help!!!
