netfilter buglog - Dec 2006 - [Bug 527] New: the check make target has a greedy debug grep

https://bugzilla.netfilter.org/bugzilla/show_bug.cgi?id=527

           Summary: the check make target has a greedy debug grep
           Product: iptables
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
        AssignedTo: laforge@netfilter.org
        ReportedBy: vapier@gentoo.org


if you have a kernel with say a '-g' in it, then KERNEL_DIR will include
the
'-g' in it, CFLAGS will include the '-g' in it, and then the
grep will think you
have -g in your CFLAGS

for example, if you use the grsec or gentoo patchset:
$ uname -r
2.6.19.1-grsec
$ uname -r
2.6.19-gentoo-r2

then your CFLAGS will look like:
-O2 -Wall -Wunused -I"/lib/modules/2.6.19.1-grsec/build"/include
-Iinclude/
-DIPTABLES_VERSION=\"1.3.7\"

and the greedy check grep will incorrectly flag this:
egrep -e '-g|-pg|IPTC_DEBUG'
