webkit-gtk-2.0 Configure error (cannot run C compiled programs) on PPC Tiger

[asiganael@…]

Trying to install midori on PPC Tiger, I hit a failure installing webkit-gtk-2.0 which is a requisite for midori:

checking for suffix of executables... 
checking whether we are cross compiling... configure: error: in `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_www_webkit-gtk-2.0/webkit-gtk-2.0/work/webkitgtk-2.0.4':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details

I'm attaching the complete main.log and configure.log

The relevant configure failure seems to be in the linking stage, because ld complains about the nature of some symbols:

It seems you're trying to use clang on a PPC system. Clang is known to perform badly for PPC targets.

Replying to cal@…:

Well, actually is not me who is trying to use clang, but webkit-gtk-2.0. Can webkit-gtk-2.0 be installed without clang? How?

Based on the compiler.blacklist lines in the webkit-gtk-2.0 Portfile, that software is apparently incompatible with most compilers.

You're using a very very very old linker. I suggest you install the ld64 port and try again.

Also, those older versions of llvm surely don't work well for ppc. 3.5 was the first that kinda worked for ppc. You should try using newer llvm, but that will require getting libc++, and that will require fixing issues with libunwind. See ​http://trac.macports.org/wiki/LibcxxOnOlderSystems#Leopardppc

Alternatively, you can try using macports-gcc-4.7 or newer for webkit-gtk, but you'll also need to use that same compiler for all of its recursive dependents.

You're very deep in unsupported territory.
