If you disable the plugins, does it work on ia64? where's the bug here? the plugin clearly documents its minimal requirement (the FINISH_DECL event callback was unfortunately never backported to gcc 4.5, despite my explicit request in their bugzilla: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41757) so either you use a new enough gcc or disable RANDSTRUCT :). also given how simple the patch is, perhaps the gentoo toolchain guys can be convinced to backport it to 4.5? (In reply to PaX Team from comment #4) > either you use a new enough gcc or disable RANDSTRUCT Given that >=sys-devel/gcc-4.6 is unable to build bootable kernels (s.a.), I guess the only option is to make the plugin depend on !ia64. (Or backport support for finish-decl.) |
