Hello Joao, The file jclips.dll only works on Windows. For UNIX/Linux, there are many different distributions/versions that I cannot provide a single DLL that will work on all versions. So, if you want to use JClips on UNIX, you have to compile your own DLL from the sources. You can download the shared library source from the web site (http://www.few.vu.nl/~mrmenken/jclips/download/jclips-library-src.zip) and compile it yourself, using a C compiler. Kind regards, Maarten
