I have two servers. Both are 64-bit boxes. Development server is running Ubuntu 7.04 and the production server is running CentOS 5. My provider does not offer Ubuntu yet. I’m stuck with CentOS 5 64-bit I have RMagick installed and working on my development box. I cannot get RMagick working on my production box. /usr/local/bin/ruby -I /home/myusername/install/RMagick-1.15.9/./lib - I /home/myusername/install/RMagick-1.15.9/./ext/RMagick PreserveAspectRatio.rb /home/myusername/install/RMagick-1.15.9/./ext/RMagick/RMagick.so: libgomp.so.1: shared object cannot be dlopen()ed - /home/myusername/ install/RMagick-1.15.9/./ext/RMagick/RMagick.so (LoadError) from /home/myusername/install/RMagick-1.15.9/./lib/RMagick.rb: 11 from /home/myusername/install/RMagick-1.15.9/./lib/rvg/rvg.rb: 31:in `require' from /home/myusername/install/RMagick-1.15.9/./lib/rvg/rvg.rb: 31 from PreserveAspectRatio.rb:1:in `require’ from PreserveAspectRatio.rb:1 post-setup.rb: PreserveAspectRatio.rb example returned error code 256 setup.rb: Too many examples failed. Search for “Help!” at [http://rmagick.rubyforge.org/install-faq.html](http://rmagick.rubyforge.org/install-faq.html). Here is the area of focus: libgomp.so.1: shared object cannot be dlopen()ed I am pretty sure that libgomp.so.1 is being resolved and actually found, however, I think this message means that the shared object cannot be dynamically opened. I have no idea how to move forward. I didn’t think setting LD\_LIBRARY\_PATH would make a difference, however, I tried setting it anyway. I was right about that one. No difference. Any pointers?? ---

Did you get anywhere with this? I’m stuck with the same problem… ---

For some reason it still seems to be requesting libgomp.so.1. /usr/local/bin/ruby -I /usr/local/src/RMagick-1.15.10/./lib -I /usr/ local/src/RMagick-1.15.10/./ext/RMagick InitialCoords.rb /usr/local/src/RMagick-1.15.10/./ext/RMagick/RMagick.so: libgomp.so.1: shared object cannot be dlopen()ed - /usr/local/src/RMagick-1.15.10/./ ext/RMagick/RMagick.so (LoadError) from /usr/local/src/RMagick-1.15.10/./lib/RMagick.rb:11 from /usr/local/src/RMagick-1.15.10/./lib/rvg/rvg.rb:31:in `require' from /usr/local/src/RMagick-1.15.10/./lib/rvg/rvg.rb:31 from InitialCoords.rb:1:in `require’ from InitialCoords.rb:1 post-setup.rb: InitialCoords.rb example returned error code 256 I feel it must be something specific to CentOS 5 as I can hardly find a reference to this issue on google. I’ve mailed the ImageMagick guys to see if they can throw any light on it. ---

Just to update in case anyone searches getting RMagic going on CentOS5… I simply substituted in GraphicsMagick for ImageMagick and everything installs fine. I probably should have thought of this earlier! On Sep 17, 8:00 pm, Andrew E. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)
