Cross-compiling is because of this: your target is not same as your host. Code compiled for the host would not excute on the different target. So cross-compile is required: A toolchain itselft excute on the host and generate code excute on the target. _______________________________________________ Clfs-support mailing list [email protected] http://lists.cross-lfs.org/listinfo.cgi/clfs-support-cross-lfs.org
