Hi Dan,
Thanks for your answer, it's helpful :). I'm currently trying this,
but I encounter a little problem : udev's Makefile usually has a boolean
'USE_KLIC' to decide whether we should link against klibc or glibc at
building time, but it seems this has changed recently... I have
installed klibc but at compil time it links to glibc, of course :). Do
you have any idea to force the usage of klibc ?
Thanks
