0) You may do better asking in a Yocto forum/list than here. Wherever you ask, tell the versions of Busybox, Yocto, and fglrx involved. 1) A ".run" file is a self extracting archive, of similar sort to what shar makes; however, it is unlikely that you could extract it with unshar. You might be able to edit it (use a copy, not the original.) 2) "Invalid magic" means that gzip is getting non-gzip data, or tar is getting a compressed archive, or some such thing. I've seen this happen when gzip gets passed a filename not ending with ".gz", and the output goes to tar; if a name ending in ".tgz" is used as a temporary file, busybox gzip may act like "cat" and send still- compressed data to stdout. I do not remember which version of Busybox this affected off the top of my head, but it was relatively recent (I think it has been solved though). The workaround I used was to redirect stdin to read from the file: - gzip -dc FILE + gzip -dc < FILE 3) While I don't remember what it is, I know that fglrx has an option that will create archives raher than installing the driver. This may be your best bet. > Thanks, > Simon Chen HTH, Isaac Dunham _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
