However, some user prefer to use command line tools. These command line tools can also be used for batch operations on all platforms, for example as part of a nightly rebuild and testing procedure. </P><P>In the current release of the system the command line tools do not provide exactly the same functionality as the graphical tool. Most importantly, there is no facility to resolve configuration conflicts interactively.</P><P>The <SPANCLASS="PRODUCTNAME">eCos</SPAN> configuration system, both graphical and command line tools, are under constant development and enhancement. Developers should note that the procedures described may change considerably in future releases. </P><DIVCLASS="SECT1"><H1CLASS="SECT1"><ANAME="DIRECTORY-TREE-STRUCTURE">Directory Tree Structure</H1><P>When building <SPANCLASS="PRODUCTNAME">eCos</SPAN> there are three main directory trees to consider: the source tree, the build tree, and the install tree.</P><P>The source tree, also known as the component repository, is read-only. It is possible to use a single component repository for any number of different configurations, and it is also possible to share a component repository between multiple users by putting it on a network drive.</P><P>The build tree contains everything that is specific to a particular configuration, including header and other files that contain configuration data, and the object files that result from compiling the system sources for this configuration. </P><P>The install tree is usually located in the <TTCLASS="FILENAME">install</TT> subdirectoryof the build tree. Once an <SPANCLASS="PRODUCTNAME">eCos</SPAN> system has been built, the installtree contains all the files needed for application development includingthe header files and the target library. By making copies of theinstall tree after a build it is possible to separate applicationdevelopment and system configuration, which may be desirable forsome organizations. </P></DIV></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"><AHREF="configuration-and-the-package-repository.html"ACCESSKEY="P">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="ecos-user-guide.html"ACCESSKEY="H">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="creating-build-tree.html"ACCESSKEY="N">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">Configuration and the Package Repository</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="configuration-and-the-package-repository.html"ACCESSKEY="U">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">Creating the Build Tree</TD></TR></TABLE></DIV></BODY></HTML>⌨️ 快捷键说明
