Cortex-M is the 'bare metal' branch of ARM where you usually

linux so druntime won't work anyway. There are some compiler

my branch that could be interesting though:

I'm aware of the druntime will not work, which is why I'm trying
to find a way to write and compile code _without_ the druntime or
phobos. See my re-post.
Also, when I tried to follow the crosstools instructions here
(http://wiki.dlang.org/GDC/Cross_Compiler) I found that the
latest crosstools was missing some of the options that are
needed.
You mean options for bare metal builds or options described in
the
wiki? I'm not sure if crosstool-NG works well with bare metal
builds.
GCC build scripts can be annoying, especially when
cross-compiling.
Your best bet is still crosstool-NG though, what exactly are the
missing options?
A couple of the options don't seem to exist in crosstools.
Specifically "Go to C compiler, select Other languages and enter
d". Pretty hard to tell the compiler to support D without this
option.
The GNU Tools for ARM scripts are specifically written for
cross-compiling, and even Canadian cross compiling. When I run
the build scripts, I get:
cat ~/mylongdir/src/gcc/gcc/BASE-VER: No such file or directory.
I looked through the shell script, but code like this
GCC_VER=`cat $SRCDIR/$GCC/gcc/BASE-VER`
GCC_VER_NAME=`echo $GCC_VER | cut -d'.' -f1,2 | sed -e 's/\./_/g'`
is a little hard for me to figure out.
Again, the problem here is not with GDC; it's that I don't know
enough about the Linux tools to know what its trying to do here
and what I can do about it.
LLVM, clang, and LDC built on the first try after 3 weekends
struggling with GCC.
