More configure fun...

[Gary Oblock <gary@amperecomputing.com>]

I'm trying to configure a GCC 12 cross build like this:

../sources/configure --prefix=$BASE/install --disable-bootstrap --enable-language=c --disable-multilib --target=arm-zephyr-eabi --with-sysroot=/home/garyzepher/zephyr/lib/libc --disable-shared --enable-__cxa_atexit --disable-tm-clone-registry --disable-libgomp --disable-libmudflap --disable-libmpx --disable-libssp --disable-libquadmath --disable-libquadmath-support --enable-lto --with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm' --enable-target-optspace --disable-nls --enable-multiarch --with-multilib-list=rmprofile --enable-languages=c,c++ --with-gnu-ld --with-gnu-as --enable-initfini-array

The original cross compiler (GCC 10 based was configured like this:

../sources/configure --build=x86_64-build_pc-linux-gnu --host=x86_64-build_pc-linux-gnu --target=arm-zephyr-eabi --prefix=/workdir/build/output/arm-zephyr-eabi --exec_prefix=/workdir/build/output/arm-zephyr-eabi --with-local-prefix=/workdir/build/output/arm-zephyr-eabi/arm-zephyr-eabi --with-headers=/workdir/build/output/arm-zephyr-eabi/arm-zephyr-eabi/include --with-newlib --enable-threads=no --disable-shared --with-pkgversion='crosstool-NG 1.24.0.378_e011758' --enable-__cxa_atexit --disable-tm-clone-registry --disable-libgomp --disable-libmudflap --disable-libmpx --disable-libssp --disable-libquadmath --disable-libquadmath-support --with-gmp=/workdir/build/build_arm/.build/arm-zephyr-eabi/buildtools --with-mpfr=/workdir/build/build_arm/.build/arm-zephyr-eabi/buildtools --with-mpc=/workdir/build/build_arm/.build/arm-zephyr-eabi/buildtools --with-isl=/workdir/build/build_arm/.build/arm-zephyr-eabi/buildtools --enable-lto --with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm' --enable-target-optspace --disable-nls --enable-multiarch --with-multilib-list=rmprofile --enable-languages=c,c++ --with-gnu-ld --with-gnu-as --enable-initfini-array

All those --with-* parameters don't seem to correlate with anything in the SDK and I
haven't got a clue as of yet how to build a cross binutils for a Zephyer OS for the Arm Thumb-2
ISA.

The build error I'm seeing at the ends of the log is:
.

.
The directory that should contain system headers does not exist:
  /home/gary/zephyr/zephyr/lib/libc/usr/include
make[2]: *** [Makefile:3255: stmp-fixinc] Error 1
make[2]: Leaving directory '/home/gary/gcc_build_cross/objdir/gcc'
make[1]: *** [Makefile:4527: install-gcc] Error 2
make[1]: Leaving directory '/home/gary/gcc_build_cross/objdir'
make: *** [Makefile:2439: install] Error 2

These are the closest looking include directories that I have. If any of them will
do what parameter lets me use it?

./zephyr/lib/libc/arcmwdt/include
fcntl.h  sys

./zephyr/lib/libc/newlib/include
errno.h  fcntl.h  sys

./zephyr/lib/libc/minimal/include
assert.h  bits  ctype.h  errno.h  fcntl.h  inttypes.h  limits.h  math.h  stdbool.h  stdint.h  stdio.h  stdlib.h  string.h  strings.h  sys  time.h

./zephyr/lib/libc/armstdc/include
stdint.h
