<p class="MsoNormal">Hi all<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Are there any instructions on how to build Dropbear with Musl (an alternative libc)? There's a
<span style="color:#1F497D">brief</span> mention of it on the Dropbear homepage, but nothing in INSTALL.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I'm building on a Raspberry Pi 3, running Raspbian 8 (Jesse). I'm attempting to build a dbclient that will run on a slightly odd Qualcomm Snapdragon based embedded Linux device. Both the Pi and the Snapdragon use the ARMv7 instruction set,
so this should be easy.<o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal">Here's what I've tried...<o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal">Got <a href="https://www.musl-libc.org/releases/musl-1.1.15.tar.gz">
https://www.musl-libc.org/releases/musl-1.1.15.tar.gz</a>.<o:p></o:p></p>
<p class="MsoNormal">./configure and then make install. All good.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Got <a href="http://zlib.net/zlib-1.2.8.tar.xz">http://zlib.net/zlib-1.2.8.tar.xz</a>.<o:p></o:p></p>
<p class="MsoNormal">export PATH="$PATH:/usr/local/musl/bin"<o:p></o:p></p>
<p class="MsoNormal">export CC=musl-gcc<o:p></o:p></p>
<p class="MsoNormal">./configure --static. make. All good.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Got <a href="https://matt.ucc.asn.au/dropbear/releases/dropbear-2016.73.tar.bz2">

<p class="MsoNormal">./configure<o:p></o:p></p>
<p class="MsoNormal">make PROGRAMS="dbclient" STATIC=1<o:p></o:p></p>
<p class="MsoNormal">Not all good :-(<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Lots of stuff built. I've got libtommath.a and libtomcrypt.a. But make dies saying:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">musl-gcc -I ../zlib-1.2.8 -I./libtomcrypt/src/headers/ -I. -I. -I../zlib-1.2.8 -DDROPBEAR_CLIENT -c -o dbutil.o dbutil.c<o:p></o:p></p>

<p class="MsoNormal">make: *** [dbutil.o] Error 1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I�m pretty sure a Musl build should even try to #include linux/types.h. Any ideas?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
