Yes you do: QEMU. http://impactlinux.com/fwl/downloads/binaries Grab the appropriate system-image-$ARCH.tar.bz2, extract it, run the dev-environment.sh script to boot qemu with the included squashfs root and a 2 gig ext2 partition mounted on /home for scratch space. It includes native development tools so you can build uClibc in there, if you like. (The release tarballs have qemu 0.9.30.2, source control has 0.9.31 but it's not in a release yet. Gotta fix the 64 bit targets first.) The root filesystem is read only, so you'll have to create a chroot under /home to test a new ldso. If you'd like a writeable /dev/hda, you'll need to read this FAQ: http://impactlinux.com/fwl/FAQ.html#add_package (Note that if you have a writable hda, making sure you fsck it as a appropriate and don't launch two qemu instances sharing the same root partition is your problem. The squashfs avoids that...) Rob -- Latency is more important than throughput. It's that simple. - Linus Torvalds _______________________________________________ uClibc mailing list [email protected] http://lists.busybox.net/mailman/listinfo/uclibc
