What happens when you include this statement in yourr main function is that your main.cc compilation unit now contains a symbol to the deal.II library. The linker will then keep libdeal_ii.so as a shared object dependency. If you do not actually use any symbol from the deal.II library itself then the linker might drop the shared object altogether and the final result is as if you never linked to deal.II in the first place. You can verify this by running "ldd" on the executable: $ ldd executable libdeal_II.so.9999 => /usr/lib64/libdeal_II.so Best, Matthias -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
