RMagick, CentOS 5 64-bit, shared object cannot be dlopen()ed

Rails
1

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/

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…

You should be able to fix it by building ImageMagick with the
–disable-openmp configure script command line option. If that doesn’t
work, try asking the ImageMagick developers.

I’ve given this a go with ./configure --disable-openmp but still get
the same error. For some reason it still seems to be requesting
libgomp.so.1.

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!
