Hi All,
I have some problem configuring Asterisk. I am using 2.6.23.1-42.fc8 kernel version.

while installing asterisk getting this error :

build_tools/make_version_h > include/asterisk/version.h.tmp
if cmp -s include/asterisk/version.h.tmp include/asterisk/version.h ; then echo; else \
mv include/asterisk/version.h.tmp include/asterisk/version.h ; \
fi

rm -f include/asterisk/version.h.tmp
if cmp -s .cleancount .lastclean ; then echo ; else \
make clean; cp -f .cleancount .lastclean;\
fi

build_tools/make_defaults_h > defaults.h.tmp
if cmp -s defaults.h.tmp defaults.h ; then echo ; else \
mv defaults.h.tmp defaults.h ; \
fi

rm -f defaults.h.tmp

So I'm assuming this is on Fedora Core 8? What step during the install are you getting this error? Are you really installing asterisk 1.2.13? You do realize they're now on 1.4.17? Anything else you need to mention during the install, like any special flags or options used? Details man or we're just as clueless as you are.
