RPM is one of the two or three standard package formats in the Unix world (the others are compressed or gzipped tar archives and Debian packages) and most Linux distributions support it.</P><P>RPM has strong support for dependency checking. This means you can create a package that cannot be installed unless certain other packages have been installed first. You can even demand that those packages are of a certain version number.</P><P>Creating an RPM takes just one command:</P><PRECLASS="SCREEN">boudewijn@maldar:~/doc/pyqt/ch18/kalam > python setup.py bdist_rpm </PRE><P>To ensure a really nice RPM, a few options should be set. The best place to set these is in the <TTCLASS="FILENAME">setup.cfg</TT> file:</P><PRECLASS="PROGRAMLISTING">[bdist_rpm]release = 1packager = Boudewijn Rempt <boud@rempt.xs4all.nl>doc_files = README COPYINGprovides = kalamrequires = python pyqtdistribution_name = SuSE 7.2 </PRE><P>Most of the options merely provide some extra meta-data, but the <TTCLASS="VARNAME">provides</TT> and <TTCLASS="VARNAME">requires</TT> options are needed by RPM to do its dependency checking. In this case, <SPANCLASS="APPLICATION">Kalam</SPAN> requires both <SPANCLASS="APPLICATION">Python</SPAN> and PyQt to be present, which is hardly a surprise! You can make these requirements more specific by also asking for a version number:</P><PRECLASS="PROGRAMLISTING">requires = python-2.2 pyqt-2.5 </PRE><P>RPM is a complicated package format in itself, and you can customize the installation process considerably by using <TTCLASS="FILENAME">.spec</TT> file. The book Maximum RPM (freely available at http://www.rpmdp.org/rpmbook/) gives detailed information on writing these files. At the moment distutils writes the file for you, based on the options in <TTCLASS="FILENAME">setup.py</TT> and <TTCLASS="FILENAME">setup.cfg</TT>. A future release of distutils will support using your own <TTCLASS="FILENAME">.spec</TT> files.</P></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLESUMMARY="Footer navigation table"WIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><A accesskey="P" href="index.lxp@lxpwrap=x8418_252ehtm.htm">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><A accesskey="H" href="index.lxp@lxpwrap=book1_252ehtm">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><A accesskey="N" href="index.lxp@lxpwrap=x8613_252ehtm.htm">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">Starting with distutils.</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><A accesskey="U" href="index.lxp@lxpwrap=c8349_252ehtm.htm">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">Windows installers</TD></TR></TABLE></DIV></BODY></HTML> </td> </tr> </table> </td> </tr> </table> ⌨️ 快捷键说明
