installing rmagick with mingw and ruby 1.9

Think I finally got it to work.

1) install ImageMagick from source using mingw, like (in msys bash) ./configure –prefix=/c/imagemagick –disable-perl && make && make install

lists a much easier way to do it (assuming you have the devkit installed):

install ImageMagick somewhere (with headers option checked, and yes add it to your path) (ImageMagick-6.6.2-Q16 known to work).

C:\> set CPATH=D:\installs\ImageMagick-6.6.2-Q16\include
C:\> set LIBRARY_PATH=D:\installs\ImageMagick-6.6.2-Q16\lib
C:\> gem install rmagick

Though he does list a few more steps that might be useful…

Note that it needs to be in a path with no spaces, or see the comments on how to use the short pathnames.

    meant “you installed ImageMAgick without the development headers checkbox checked!”

  7. Also note that when you install imagemagick you should install it to a directory without any space in its name. Thus the default c:\program files(x86) won’t be good. Or if you install it there create an alias (symlink) with “MKLINK /d c:\progx86 c:\program files(x86)” and then set CPATH and LIBRARY_PATH to use this new aliased directory. Then it will compile just fine and dandy 🙂

    MKLINK only works in vista and windows 7(!)

    All in all it’s not that difficult at all. Few simple steps and that’s it. It compiled and installed under 3 minutes on my not too new core2 duo laptop w/ 4 gigs of ram on win 7 ultimate

  8. You can use the short file names for paths with spaces.

  9. I fought with installing Rmagick for DAYS on Windows 7 with no luck! rdp-rmagick works wonderfully!

    How did you know about that gem? Where would I find that out? I googled everything possible for a solution to installing rmagick gem.
