Iain Buclaw <ibuclaw at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ibuclaw at gcc dot gnu.org --- Comment #6 from Iain Buclaw <ibuclaw at gcc dot gnu.org> --- On a cursory glance, these are all targets that don't build libdruntime by default? So naturally these won't have any runtime modules installed with them. There's usually good reason these targets don't build druntime - missing C bindings in libdruntime so can't build the library. - missing an implementation of config/${cpu_type}/${cpu_type}-d.cc so the target isn't even classified at compile-time with version(). See libphobos/configure.tgt. sparc64-*-linux* was added recently after some testing by Sam. Others such as ia64 and m68k I expect to have zero support. You can try configuring with: --enable-libphobos --with-libphobos-druntime-only With the expectation that some won't pass.
