compiling the toolchain, but I guess that without your files it
would not work anyway, right? (;
You can and in this case you should make the toolchain first
without library. It is possible to compile programs with gdc
without the library as long as only c style functions are used.
A working linker script is needed to make the executable and a
proper startup file is needed to make the executable work in the
target platform. A suitable bootloader is needed to transfer the
executable to the target processor.
When all these are working, the runtime library is needed.
The toolchain in https://launchpad.net/gcc-arm-embedded seems to
be a good starting point for arm cortex processors. It has all
the tools and also suitable linker scripts and startup files. But
it is not aware of D.
As mentioned earlier in this thread, nobody has made this yet. So
there is not an easy way to go. As long as gdc is not part of the
gcc package, some extra work is always needed.
If the toolchain works, it is worth of try to replace gcc in
there with the newest gcc with d patches. Some modifications are
needed in the build script to enable d and disable libphobos.
