Hi, LD_LIBRARY_PATH is only used at the runtime for the programs to search the dynamic libraries. Check out the compilation at the beggining (compilation for the arf directory), I'm pretty sure some of the classes just did not compile, and so did not create some object files (.o), and that's why the link crashed. Since GATE is organized in thematic source directories, when a compilation problem occurs, it just stops the compilation in this directory, and others continue, that leads to link problem.

I would try adding the path to your .o-files to LD_LIBRARY_PATH, like I wrote in the post to Congwu. The default path where they end up is "gate_your_version/tmp/Linux-g++/Gate", you can check that directory to see if you find the files there (the ones which produce the undefined references, such as GateARFDataToRoot etc.). If that doesn't work, I don't know! =) /Ida <div class="gmail_quote">2009/10/9 Chris Reynolds <<a href="mailto:C.Reynolds@westminster.ac.uk" target="_blank">C.Reynolds@westminster.ac.uk</a>><div><div></div><div class="h5"> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, I'm also have linker issues on Ubuntu.
