Hello, I've been working on porting GNU libc (glibc) to OpenSolaris (see [0] for source code and other downloads). I've also ported NPTL (the glibc thread library), using the corresponding OpenSolaris syscalls. I haven't benchmarked much, but I suspect speed should be comparable to "native" OpenSolaris. At this point I have a working chroot with a number of packages installed and working, and I hope to have a zone booting soon. Xorg, GNOME, and gdb all work. I also have a number of Solaris binaries working, including truss, dladm, zfs, and zpool. (I haven't tried, but it should be fairly straightforward to get dtrace working.) In order to get these working, I implemented additional OpenSolaris extensions (mostly trivial syscall wrappers). Examples are the functions defined in ucred.h, priv.h, and sys/pset.h.
Since nexenta is trying to be "OpenSolaris with the GNU userland", it makes sense to use glibc. This would also solve the legal problem that Debian had with linking Sun's libc with dpkg [1]. glibc is licensed under LGPL with a linking exception, so linking CDDL code against the glibc is also legal. In keeping with past glibc ports (e.g. kFreeBSD, kNetBSD), I've used the target string i486-kopensolaris-gnu (the 64-bit target would be x86_64-kopensolaris-gnu). If you want to test this out in a chroot, there's a bunch of pre-built i386 binaries available [2] that can be just untarred into a directory. You'll also need to mount /proc, /dev, and /devices in the chroot via "lofs" (this won't be needed if done in a zone). Many applications will require OpenSolaris headers to build, which can just be copied from an OpenSolaris/Nexenta box (just don't overwrite any headers installed by glibc). -- David [0] http://csclub.uwaterloo.ca/~dtbartle/opensolaris/ [1] http://lists.debian.org/debian-devel/2006/04/msg00069.html [2] http://csclub.uwaterloo.ca/~mspang/opensolaris/builds/ _______________________________________________ gnusol-devel mailing list gnusol-devel@lists.sonic.net http://lists.sonic.net/mailman/listinfo/gnusol-devel
