# If make fails with an error like this:
# lex.l:429: `yytext_ptr' undeclared (first use in this function)
# and you have flex 2.5.31 installed, downgrade to 2.5.27, come back here,
# run 'make distclean' then run configure and make again, then upgrade flex
# back to 2.5.31 when you're done here.  I got this error with modutils
# 2.4.26 and 2.4.27 (with flex 2.5.31).  It seems to build OK with flex
# 2.5.33.

## If you use gcc 4.x and make fails with an error like this:
# obj_kallsyms.c: In function 'obj32_kallsyms':
# obj_kallsyms.c:204: error: invalid lvalue in assignment
# obj_kallsyms.c:279: error: invalid lvalue in assignment
## apply this patch:
wget -nc http://englanders.cc/pub/linux/patches/notmine/\
modutils-gcc40.patch &&
patch -p1 < modutils-gcc40.patch

make

# Become root to install it

# If you use kmod and use the /etc/cron.(daily|hourly|monthly|weekly) dirs,
# create a /etc/cron.hourly/kmod script to run every hour unloading unused
# modules.  You can of course just add a cron job directly to root's crontab
# to do this too.
echo '#!/bin/sh' > /etc/cron.hourly/kmod
