"Headers Present But Cannot Be Compiled" I have seen that configure message several times. The most recent was with building kdepim. That particular error was about bluetooth/bluetooth.h and is described exactly here: http://flameeyes.eu/autotools-mythbuster/autoconf/finding.html#autoconf.hea… The specific problem file is: kdepim/configure.in.in The other times I have seen that error was with respect to linux/cdrom.h. The problematic files are: kdebase/kioslave/media/configure.in.in kdemultimedia/configure.in.in kdemultimedia/kscd/libwm/configure.in.in I grepped the source tree and did not find any other files. Hopefully you can use that information to fix the problem! :) Darrell
