Build Variables </h1> </div> <h4> <a id="id3649975" name="id3649975"></a>Setting Host and Target </h4> <p> During the building of the cross-compile tools you will need to set a few variables that will be dependent on your particular needs. The first variable will be the triplet of the <tt class="envar">HOST</tt> machine. You will need to set the <tt class="envar">CHOST</tt> triplet to match your particular needs. To set this information you can issue the following command: </p> <pre class="userinput"><kbd class="command">export LFS_HOST="`echo ${MACHTYPE} | sed -e 's/unknown/cross/g' -e 's/-pc-/-cross-/g'`"</kbd></pre> <p> Now we will set our Target Triplet: </p> <p> For a MIPS Little Endian Machine: </p> <pre class="userinput"><kbd class="command">export LFS_TARGET="mipsel-unknown-linux-gnu"</kbd></pre> <p> For a MIPS Big Endian Machine: </p> <pre class="userinput"><kbd class="command">export LFS_TARGET="mips-unknown-linux-gnu"</kbd></pre> <p> Now we will add these to <tt class="filename">~/.bashrc</tt>, just in case you have to exit and restart building later: </p> <pre class="userinput"><kbd class="command">echo export LFS_HOST=\""${LFS_HOST}\"" >> ~/.bashrcecho export LFS_TARGET=\""${LFS_TARGET}\"" >> ~/.bashrc</kbd></pre> </div> <div class="navfooter"> <ul> <li class="prev"> <a accesskey="p" href="cflags.html" title="Build CFLAGS">Prev</a> <p> Build CFLAGS </p> </li> <li class="next"> <a accesskey="n" href="linux-libc-headers.html" title= "Linux-Libc-Headers-2.6.12.0">Next</a> <p> Linux-Libc-Headers-2.6.12.0 </p> </li> <li class="up"> <a accesskey="u" href="chapter.html" title= "Chapter 5.
