After hacking away a bit more at the problem, I think I found a
solution. I'm posting it in case anyone else runs into the same problems
and this solution works for them.
The trick was noticing that despite the --host and --with-arch flags,
the configure script still wasn't convinced it was doing a cross-compile:
> checking whether we are cross compiling... no
Digging into the configure script revealed that it was looking for a
binary called <host_triplet>-gcc in the PATH that already had the
correct -arch settings built-in.
So I created the following trampoline script
'x86_64-apple-darwin9.8.0-gcc' and stuck it in my path:
#!/bin/sh
gcc -arch x86_64 $@
Now configure correctly detects that it's in cross-compile mode.
I also found that I could avoid creating the trampoline altogether by
setting the CC variable explicitly like so:
$ ./configure --host=x86_64-apple-darwin9.8.0 --with-arch=x86_64 CC="gcc
-arch x86_64"
Much more elegant. The only thing left is to point configure at
cross-compiled versions of its dependent libraries (libfreetype and
libxml2). (You could also use pango instead of libxml2.)
$ ./configure --host=x86_64-apple-darwin9.8.0 --with-arch=x86_64 CC="gcc
-arch x86_64" --enable-libxml2 LIBXML2_LIBS="-L/cross-prefix/lib -lxml2"
LIBXML2_CFLAGS="-I/cross-prefix/include/libxml2"
--with-freetype-config=/cross-prefix/bin/freetype-config
Sweet success.
