------- Comment #4 from pinskia at gcc dot gnu dot org 2006-05-24 09:26 ------- try with --disable-multilib. I bet you don't have the 64bit userland installed.
Please read: http://gcc.gnu.org/install/specific.html#x-x-solaris2 When configuring on a Solaris 7 or later system that is running a kernel that supports only 32-bit binaries, one must configure with --disable-multilib, since we will not be able to build the 64-bit target libraries. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27752
