Its fixed now. There was an older version of the jpeg lib from Mac Ports which needed to be removed before running the Image Magick install script.

Hi,

I installed ImageMagick with this script here because it seemed the most up to date one and I had trouble with the Mac Ports installation: http://github.com/masterkain/ImageMagick-sl

I get the following error in some ImageMagick commands:

Magick::ImageMagickError: Wrong JPEG library version: library is 70, caller expects 62 `’ @ jpeg.c/EmitMessage/232

Can anybody advice? What do I need to do?

Ok, so I just found a solution. I just compiled it by itself first:

cd ruby-1.8.7-p72/ext/readline/
ruby extconf.rb
sudo make
sudo make install

and then I was able to install Ruby in /usr/local. Why? I’m not sure.

@Doug Hmmm, not sure what the problem could be offhand, but if you post the error message and any other special notes on your installation, I might be able to help you out

Hi Julie. Thanks for the great information here. Since Dan Benjamin doesn’t have his comments enabled on the post about installing Ruby in /usr/local, I thought I’d inquire with you. I’ve gone back to using the default Ruby for now but when I tried “make”, I got some errors compiling readline. Do you know what that’s about? Thanks again.

Thanks, Jerome! Glad we could help you out :)

And thanks for the tip on the ImageMagick URL – I’ve set up a new Pastie and updated the link in the post.

Great resource. However, the ftp link for ImageMagick is wrong. The ImageMagick file should read:

ImageMagick-6.5.6-1.tar.gz
instead of ImageMagick-6.5.5-6.tar.gz

Thanks again, works great.
