</p><p><br>
</p><p>This is the first mail After i subscribed the mailing list.</p>
<p><br>
</p><p>I want to know the method cross-compile dropbear on uclinux with arm-elf-gcc</p>
<p><br>
</p><p>sorry for poor englisth...</p>
<p><br>
</p><p><br>
</p><p><Enviroment></p>
<p>1. OS : Fedora 11</p>
<p>2. Zlib : zlib-1.2.3</p>
<p>3. dropbear : dropbear -0.52</p>
<p>4. Target : kernel 2.4.x uclinux</p>
<p>5. uClibc : uClibc-0.9.27</p>
<p><br>
</p><p><Install process></p>
<p><br>
</p><p>1. I cross-compiled uClibc with arm-elf-gcc, As a result, i got "arm-uclibc-gcc"</p>
<p>2. I cross-compiled zlib-1.2.3 </p>
