dnl as-scrub-include.m4 0.0.1
dnl autostars m4 macro for scrubbing CFLAGS of system include dirs
dnl because gcc 3.x complains about including system including dirs
dnl
dnl thomas@apestaart.org
dnl
dnl This macro uses output of cpp -v and expects it to contain text that
dnl looks a little bit like this:
dnl #include <...> search starts here:
dnl /usr/local/include
dnl /usr/lib/gcc-lib/i386-redhat-linux/3.2/include
dnl /usr/include
dnl End of search list.
dnl AS_SCRUB_INCLUDE(VAR)
dnl example
dnl AS_SCRUB_INCLUDE(CFLAGS)
dnl will remove all system include dirs from the given CFLAGS
AC_DEFUN([AS_SCRUB_INCLUDE],
[
GIVEN_CFLAGS=$[$1]
INCLUDE_DIRS=`echo | cpp -v 2>&1`
dnl remove everything from this output between the "starts here" and "End of"
dnl line
INCLUDE_DIRS=`echo $INCLUDE_DIRS | sed -e 's/.*<...> search starts here://' | sed -e 's/End of search list.*//'`
for dir in $INCLUDE_DIRS; do
GIVEN_CFLAGS=`echo $GIVEN_CFLAGS | sed -e "s;-I$dir ;;" | sed -e "s;-I$dir$;;"`
done
[$1]=$GIVEN_CFLAGS
