Hi Ronan,

Look through this search results. I think you'll find the answer here:

ok Steven, thank for your help.

i tried a lot to solve the problem, and i found that the OpenMP
resource that rMagick uses to access imagemagick is not set in the
last linux ubuntu version, Hardy Heron. the solution maybe was to
recompile the GCC compiler (!) to make it run correctly.

i'm newbie in linux and rails, so it was what i found, i'm not shure
it's correct.

last week (thanks God!!) I got a mac mini and now it's perfect
running! :.D

I was in the same boat and DID choose to recompile gcc. Your
suspicion was correct. It all then worked. Though it wasn't fun :)

For anyone else running into the same error (and obtained gcc via
build-essential) you can fix it by doing the following:

1. Uninstall build-essential with 'sudo apt-get remove build-
essential'
2. Reinstall with gcc v 4.1: 'sudo apt-get install build-essential
libglut3-dev gcc-4.1 g++-4.1 -y'
3. Tell system to use this version of gcc: 'sudo update-alternatives --
install /usr/bin/gcc gcc /usr/bin/gcc-4.1 60 --slave /usr/bin/g++ g++ /
usr/bin/g++-4.1
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.2
40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.2'
4. Re-configure, make, and install ImageMagick
5. Uninstall rmagick gem
6. Reinstall rmagick gem

on ubuntu, you can also use the apt package libmagick9-dev rather than
compile imagemagick/gcc, etc.
(sudo aptitude install libmagick9-dev)
