Hi Jonathan
well, your approach to the problem solving is a few better:
rm -rf bld/gcc
mkdir bld/gcc 2>/dev/null ; cd bld/gcc
export STAGE1_CFLAGS="--sysroot=/"
export STAGE1_CXXFLAGS="--sysroot=/"
../../gcc-4.8.2/configure \
--prefix=$PFX \
--with-gmp=$PFX \
--with-mpfr=$PFX \
--with-mpc=$PFX \
&& make STAGE1_CFLAGS=$STAGE1_CFLAGS STAGE1_CXXFLAGS=$STAGE1_CXXFLAGS
^C
find -name config.status -print0 | xargs -0 egrep '"C(XX)?FLAGS"'
./config.status:S["CXXFLAGS"]="-g -O2"
./config.status:S["CFLAGS"]="-g -O2"
./libiberty/config.status:S["CFLAGS"]="--sysroot=/"
./lto-plugin/config.status:S["CFLAGS"]="--sysroot=/"
./gcc/config.status:S["CXXFLAGS"]="--sysroot=/ "
./gcc/config.status:S["CFLAGS"]="--sysroot=/ "
./intl/config.status:S["CFLAGS"]="--sysroot=/"
The only thing. pls note on upper two string of search results. Still default
"-g O2". ie, instead of just specifying CFLAGS/CXXFLAGS to be used at all
process stages, including the congigure pass (by either of means: prefixed to
configure, passed to make directly or via -e swithch) I will need to have
C(XX)?FLAGS set (for configure purposes, otherwise it wont work) and for stage1
STAGE1_C(XX)?FLAGS, that is doubling [my] configuration efforts.
Seems to be a few illogical, but it is ok. I have already found my way of
handling that, namely: sed -ri 's/^(stage1_cflags="-g)"$/\1 $CFLAGS"/'
configure
Was it funny? Certainly. So why am I trying to prevent others from doing same??
Best Regards
