Here’s how far we’ve come.

You can install the binary ruby from Installer.app, however, it doesn’t run anything useful, and segfaults, errors out, or otherwise refuses to operate.

# ruby setup.rb
setup.rb:1585: [BUG] terminated node (0x15c444)

So, the process is, install the ARM binutils (gcc and friends) with macports. This GCC is ghetto, and doesn’t support everything that regular Darwin GCC does.

sudo port install arm-apple-darwin-binutils

Download ruby, untar it, and apply this patch:

Edit mkconfig.rb and comment-out the line near the end that begins, Fileutils.touch

Edit ext/Setup and uncomment the first line. Also uncomment socket, digest, digest/md5, etc, fcntl, stringio, syck and zlib.

$ autoconf
$ CC=arm-apple-darwin-cc CPP=llvm-cpp ./configure –host=arm-apple-darwin  –disable-ipv6 –prefix=/tmp

Edit ext/getaddrinfo.c and comment out “gai_strerror” from about line 207. Edit ext/socket/addrinfo.h and comment out the code related to “extern char *gair_strerror”

$ make
$ make install

Hopefully it all compiles for you and you can scp ruby from /tmp/lib and /tmp/bin into your iphone. I just can’t get it to work. Basically, the symbols from those ext/ libraries aren’t available during the final part of “make”.
