Install RMagick on openSUSE 11.3 - gem failed to build its extension - ruby

Question

I have RVM installed on openSUSE 11.3. My preferred Ruby version is MRI 1.9.2p136.
I tried to install RMagick gem and got the following output:
Building native extensions. This could take a while...
ERROR: Error installing rmagick:

Actually, the error doesn't tell me anything. I have already installed all basic development packages and ImageMagick headers. Am I still missing some development binaries?

Answer 1

Ok, thanks for your post. I had the same problem, but the answer was quite easy.
I've installed the bzip2 development headers.
zypper in libbz2-devel
After this tasks the installation of rmagick worked. (Maybe you have to install the complete bzip2 package?)

Answer 2

So, finally:
to install rmagick gem on openSUSE 11.3, prerequisites are:
ImageMagick-devel, libMagick++-devel, libbz2-devel
su -c 'zypper in ImageMagick-devel libMagick++-devel libbz2-devel' -

Answer 3

I had the same problem. I installed all the packages mentioned in the rest of the thread, to no avail. In the end it took a couple which weren't mentioned, but which had popped up in error messages - the packages I had to install were tdl and libtool.
