Hi Kiyan,

Your problem is probably due to an incompatibility between the g++ you 
have installed on your system, and the one that the eplex CLPCBC library 
is compiled on.

The if_osiclpcbc tarball includes the CLP/CBC solvers, statically linked 
in, so you don't need to compile them yourself. However, because CLP/CBC 
requires the libstdc++ library that comes with g++, and different 
versions of g++ have mutually incompatible versions of this library, you 
must have a version of the library that matches the one that the CLP/CBC 
   is compiled with.

We used to distribute a matching version of the library with the 
tarball, but it got very complicated to locate the correct libstdc++ 
correctly, and there were also other possible potential 
incompatibilities with other third party components that uses libstdc++,
so we stopped doing this.

So you need to either find the libstdc++.so that matches the version 
that ECLiPSe and the CLP/CBC is compiled with. Unfortunately, I am not 
sure which version of gcc/g++ is used to compiled the x86_64_linux 
version of ECLiPSe -- recent versions of the x86_64_linux builds are 
done on machines I do not have access to.

The other alternative is to build ECLiPSe, as well as CLP/CBC, from 
source yourself. In this case, you can be certain that the same version 
of gcc/g++ is used. However, you need to use the main branch of CBC, 
rather than the stable branch, as we use some features that are still 
not found on the stable branch, as of a few months ago, when I last 
checked.  You may want to read the ECLiPSe Build-and-Test-Setup Guide 
(distributed with ECLiPSe, but this is in MS Word format, a pdf version 
is available at:

http://www.eclipse-clp.org/reports/SetupGuide.pdf

If anyone knows of a better way of dealing with incompatibilities 
between libstdc++ libraries for gcc, so that we can distribute binaries 
that will run across a larger range of installed gcc/g++ versions, do 
please let me know!

Cheers,

Kish
