Follow-up Comment #4, sr#110537 (group autoconf): Autoconf doesn't have generic support for --with-sysroot. Like all --with and --enable options, if you pass it to a configure script that doesn't define what it does using AC_ARG_WITH, it's just ignored.
In order to add a generic --with-sysroot option, we would first need to work out a detailed spec for what it should do, and a plan for how to add it without stepping on the toes of configure scripts that *do* already have an AC_ARG_WITH([sysroot], ...). Someone other than me needs to lead that design discussion; I don't have the time nor do I have any relevant experience. This is definitely not going to happen for 2.72. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/support/?110537> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
