after spending some time and having numerous misadventures, i finally have davfs working on my c760 running cacko 1.22b.
i used kunitake's davfs and libxml2 packages, along with the libcrypt and libssl from his feed (but not the whole package so as not to break cacko) because davfs was compiled against openssl 0.9.6.
the davfs module needs coda support in the kernel, which isn't available in cacko, so i compiled it myself and copied it over.
i tried recompiling davfs so it would work against openssl 0.9.7, but my cross compiler setup is good enough for the kernel but completely broken for anything with library
dependancies, and i couldn't find a dev-img with xscale support for native compiling.
kunitake's archive was available yesterday when i started playing with all this:
http://www.linux-ipv6.org/~kunitake/zaurus/feedbut today it's a no-go. i used archive.org to grab the packages and put them up along with coda.o, libcrypt.so.0.9.6, and libssl.so.0.9.6. you may get some unexpected end of file errors from the ipk i've mirrored, but they should work :
http://spic.net/z/if anyone has info on a dev-img that works for building cacko, I'd appreciate it and will use it to rebuild the packages for the cacko feeds.
now aside from updating davfs, all we need is an applet to handle the mounting.
