Hi, I'm building bare metal toolchains with newlib & atm I'm configuring using --with-headers=<path to>/newlib/libc/include - make install-gcc, build & install newlib then go back & make all && make install in gcc build folder. That leaves <prefix>/arm-eabi/sys-include in place which the toolchain then uses unless I delete it Should I delete it before building newlib? after building the toolchain? or should I go back and reconfigure gcc from the beginning without the --with-headers option? I used to build using --with-newlib and --without headers but ended up switching to this after some problems with the headers, unfortunately I've lost the notes I made at the time and can't remember exactly what the problem was.
