OK, I'll rework my first very dirty hack (just to test it) which I made available (probably only for about two weeks from now) as http://arbeit.hilses.de/hw/vdr-dirtyhack.patch It's against 1.3.34. It's very badly done as it just allocates a buffer (of 1kB) for all strings that were unallocated before (and meant to be allocated by sscanf). If anyone around knows the most common (not glibc-based) approach to solve this problem, I'd like to know. Otherwise I'll try to find a way doing this without causing too much havoc in the codebase. A few additional uclibc-related notes: - I found that only newest 0.9.28 happened to have the threading stuff needed to compile vdr. I.e., not working with Gentoo embedded right now. It worked with uclibc's buildroot just fine. - Using uclibc and only busybox' stripped down sysv init implementation lead to boot time of 35 sec on my 200MHz Pentium-MMX with a mostly static kernel (only module is lirc). Basic VDR's CPU utilization is at 10%. I found this impressive... 13secs is due to BIOS and grub. - A lot of plugins are working quite well (mplayer, mp3 still untested, osdteletext, screenshot, tvonscreen, dvd are working). - Kernel+mplayer+above mentioned plugins+libs+vdr+lirc+busybox is around 16MB atm. I'll make a build description, an updated patch and some config files for busybox available ASAP. I.e., probably around tomorrow... -hwh
