75 <p class="paragraph_style">Installation depends on some packages including:<br /><br />- liboasys –> tcl8.5, libxerces27<br />- dtn –> adduser<br /></p>
76 <p class="paragraph_style"><br /></p>
77 <p class="paragraph_style"><span class="style_4">IMPORTANT NOTES</span>:<br /><br />- the dependencies are normally resolved automatically if you activate one of the extras repository (we have tested with extras-devel repository active)<br />- packages should now be completely <span class="style_5">optified</span> then the installation of liboasys, dtn and python-dtn (with their dependencies) requires about 2% of rootfs partition<br />- we recommend to execute in x-terminal as root these commands after installation to clean local temp repository<br /> apt-get check<br /> apt.get autoclean<br /> apt-get clean<br /></p>
78 <p class="paragraph_style"><br /></p>
79 <p class="paragraph_style"><span class="style_4">OTHER NOTES</span>:<br /><br />- in this DTN packages compiled for Maemo 5 all features are enabled (also external convergence layer support and external decision plane support)<br />- in repository tree are available also i386 architecture packages and sources packages for Scratchbox Virtual Cross-Compilation Machine (used by Maemo 5 SDK)<br /></p>
