Using the sample configuration, such as armeb-unknown-eabi, does not build g++. When you go into menuconfig, you are not given the option to build any language other than C when you select bare- metal. I do not see how this could just work....I don't use menuconfig. We use RPMs or RTEMS test scripts.
That is "ct-ng menuconfig"
RPMs? Like the Red Hat package manager? I am confused.
The RTEMS Project (http://www.rtems.org) provides prebuilt toolsets for various GNU/Linux distributions along with binaries for MS-Windows. We use binutils, gcc, newlib, and gdb. The targets are *-rtems* instead of say *-elf but the underlying source code is the same and the *-rtems* target is usually a close cousin of the *-elf* on the same architecture.
With the RTEMS target, you are just going to get more functionality -- tasking, filesystem, TCP/IP etc.
So when distributing tools they are in RPM. When testing to report to the GCC list, they are automated build scripts. That's what I was referring to.

You want to do bare metal. Get behind the script. :-D
Well that depends on the intent of the project.
If you are just building a *-elf toolset from source using newlib, it isn't that difficult by hand. Just the proper incantation of a few configure lines. :)
Untar binutils, gcc, newlib, and gdb mv or symlib newlib's libgloss and newlib under gcc.
mkdir b-binutils cd b-binutils ../binutils/configure --target=TTT --prefix=PPP make all install cd ..
mkdir b-gcc cd b-gcc ../gcc/configure --target=TTT --prefix=PPP \ --with-newlib --enable-languages=c,c++ make all install cd ..
mkdir b-gdb cd b-gdb # add --enable-sim if you want simulator support ../gdb/configure --target=TTT --prefix=PPP make all install
At that point you should have a toolset if the C++ is buildable. The PATH step is important because you must have a cross assembler in your PATH.
