By default debian ppc is 32bit. The kernel is 64bit and some libraries have 64bit versions built, but for the most part the system is 32bit. Unlike x86_64, ppc (and sparc and a number of others) are usualyl less efficient in 64bit mode due to pointer sizes and cache overhead, and don't gain anything from going 64bit unless the application really has a need for lots of memory space. Hence no ppc64 port in debian. I even tried doing 'linux32 dpkg-buildpackage' which makes the uname -m claim to be 32bit, and even then with 32bit userspace and a kernel claiming to be 32bit, it still failed the same way. -- Len Sorensen _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
