|colspan = "3"|To ensure that an Open C application will work, it is worthwhile to create dependencies to any Open C plug-in components that are required to run the application. This way, the user will be warned during installation if Open C libraries are not present in the device.<br>To create dependencies to other components by declaring the required components in the PKG file:<br>&nbsp;&nbsp;(componentUID), version-range, <nowiki>{</nowiki>"Component name for lang 1","Component name for lang n",...<nowiki>}</nowiki><br>For Open C plug-in components, the dependencies can be declared as follows:<br>&nbsp;&nbsp;(0x20009a80), 1, 0, 0, <nowiki>{</nowiki>"Symbian OS PIPS"<nowiki>}</nowiki><br>&nbsp;&nbsp;(0x20009aa2), 1, 0, 0, <nowiki>{</nowiki>"Symbian OS STDIOSERVER"<nowiki>}</nowiki><br>&nbsp;&nbsp;(0x10281f34), 1, 0, 0, <nowiki>{</nowiki>"Open C LIBSSL"<nowiki>}</nowiki><br>&nbsp;&nbsp;(0x10281f2c), 1, 0, 0, <nowiki>{</nowiki>"Open C GLIBRARY"<nowiki>}</nowiki><br>In the above example, the dependencies are created to the four OpenC components:<br>&nbsp;&nbsp;<nowiki>’</nowiki>Symbian OS STDIOSERVER<nowiki>’</nowiki> (installed from stdioserver.sis),<br>&nbsp;&nbsp;<nowiki>’</nowiki>Symbian OS PIPS<nowiki>’</nowiki> (pips_s60_wp.sis),<br>&nbsp;&nbsp;<nowiki>’</nowiki>Open C LIBSSL<nowiki>’</nowiki> (openc_ssl.sis),<br>&nbsp;&nbsp;<nowiki>’</nowiki>Open C GLIBRARY<nowiki>’</nowiki> (openc_glib.sis),<br>Dependencies may also be targeted to specific component versions:<br>&nbsp;&nbsp;(0x0123BABE), 1, 2, 0 <nowiki>~</nowiki> *, *, *, <nowiki>{</nowiki>"ComponentName"<nowiki>}</nowiki> ; Version greater than or equal to 1.2.0 is required<br>&nbsp;&nbsp;(0x0123BABE), 1, 2, 0 <nowiki>~</nowiki> 2, 0, 0, <nowiki>{</nowiki>"ComponentName"<nowiki>}</nowiki> ; Version from 1.2.0 to 2.00 required<br>&nbsp;&nbsp;(0x0123BABE), *, *, * <nowiki>~</nowiki> 2, 0, 0, <nowiki>{</nowiki>"ComponentName"<nowiki>}</nowiki> ; Any older version up to (and including) 2.0.0 is required
