Hi!
I am tried to use step-by-step instructions from wiki
(http://wiki.dlang.org/Bare_Metal_ARM_Cortex-M_GDC_Cross_Compiler)
to build toolchain on Debian GNU/Linux 8 and got this error
after execute "make -j4 all-target-libgcc":

I just wanted to let you know that in case you couldn't get a
build on your host PC, there may be another way to get a GDC
ARM Cortex-M cross-compiler.
It has come to my attention that the prebuilt binaries at
http://gdcproject.org/downloads are capable of creating ARM
Cortex-M binaries. I just tested it myself.
I used the arm-linux-gnueabihf build, and the command I used
for my STM32F4 (ARM Cortex-M4F) was:
arm-gdcproject-linux-gnueabi-gdc -fno-emit-moduleinfo -frelease
-mthumb -mcpu=cortex-m4 -fdata-sections -ffunction-sections -c
start.d
The key is to simply add the platform flags: -mthumb
-mcpu=cortex-m4
I hope that helps.

That's correct. All ARM GCC compilers can generate code for all
ARM variants (the hf compiler can generate softfloat code and the
softfloat compiler can generate hf code as well). The difference
between the compilers are the shipped libraries. You probably
can't use the shipped libgcc etc from these compilers for thumb
targets.
