The error basically says the Linux run-time loader cannot find the library you linked with. Normally on Linux CMake automatically deals with all such issues in the build tree so I don't understand why you are getting an error in that case. It may be the version of CMake you are using with CentOS has a bug. Anyhow, one experiment you should try on CentOS is to build your favorite version of CMake there. By the way, a workaround is to set the LD_LIBRARY_PATH environment variable to the directory where the shared library is located so that should allow you to test further on CentOS. I will take a look at this once you share your work with a patch. Alan __________________________ Alan W.
