------- Comment #3 from simon at pushface dot org 2009-12-29 18:06 ------- Sorry if I've caused confusion by misunderstanding the reporting system.
I can build GCC4.4.2[i386-apple-darwin10.2.0] using GNAT-GPL-2009[i386-apple-darwin10.2.0]. I then try to build GCC4.4.2[x86_64-apple-darwin10.2.0] using GCC4.4.2[i386-apple-darwin10.2.0], with the reported results. So the problem arises in the middle of the compiler build process; the original host compiler was i386-apple-darwin10.2.0 but by the time the error occurs we're using the stage3 x86_64-apple-darwin10.2.0 compiler (of course it can never be installed because it can't build its RTS). I've been using --build=x86_64-apple-darwin10.2.0 to indicate that I want to build a 64-bit compiler, is that not the right method? (I picked this up from AdaCore's GNAT-GPL-2009, which is x86_64 built on Leopard; it's not a technique mentioned in documentation at gcc.gnu.org). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42518
