So for example, if your target file system is mounted on <CODE>/mnt/target</CODE>and your tarballs are in <CODE>/root</CODE>, you would do<P><PRE> cd /mnt/target/usr/src tar -xzvf /root/MAKEDEV-2.5.tar.gz</PRE><P><P>Don't be completely lame and copy the tarball to the place where you are goingto extract it ;-><P><P>Normally when you install software, you are installing it onto the systemthat is running. We don't want to do that though, we want to install itas though <CODE>/mnt/target</CODE> is the root filesystem. Different packageshave different ways of letting you do this. For MAKEDEV you do<P><PRE> ROOT=/mnt/target make install</PRE><P><P>You need to look out for these options in the README and INSTALL filesor by doing a <CODE>./configure --help</CODE>.<P><P>Have a look in MAKEDEV's <CODE>Makefile</CODE> to see what it does with the<CODE>ROOT</CODE> varible that we set in that command. Then have a lookin the man page by doing <CODE>man ./MAKEDEV.man</CODE> to see how it works. You'll find that the way to make our device files is to<CODE>cd /mnt/target/dev</CODE> and do <CODE>./MAKEDEV generic</CODE>.Do an <CODE>ls</CODE> to see all the wonderful device files it has madefor you.<P><HR><A HREF="buildMin-4.html">Next</A><A HREF="buildMin-2.html">Previous</A><A HREF="buildMin.html#toc3">Contents</A></BODY></HTML>⌨️ 快捷键说明
