Problems building raspberry bsp

[Markus Krupinsky]

Hi guys,

I've tried compiling rtems like described here:
http://alanstechnotes.blogspot.de/2013/03/rtems-on-raspberry-pi.html
Sadly I'm not able to build rtems using this tutorial - it fails with a
missing pid_t symbol.

System:
Archlinux (newest update) and therefore gcc6

Source-Builder:
master, origin git://git.rtems.org/rtems-source-builder.git

build cmd (after virtualenv2 setup like described in doc):
../source-builder/sb-set-builder --log=build.log
--prefix=~/workspace/rtems/compiler/4.12 4.12/rtems-arm

I wanted to be at latest dev-branch of rtems as recommended from the
mailing list.
4.11, origin git://git.rtems.org/rtems.git
./bootstrap && mkdir ../build-rpi &&cd ../build-rpi
export PATH="$(pwd)/../../compiler/4.12/bin:$PATH"
../rtems-git/configure --target=arm-rtems4.12
--enable-rtemsbsp=raspberrypi --enable-tests=samples --enable-networking
--enable-posix --prefix=$(pwd)/../bsps/4.12


Until here I got everything setup. But trying make install results in
the following error (I pasted it for better formatting on
http://paste.debian.net/894232/ ):

I tried several things. The only thing which worked was the master
branch of rtems which is quite old.
Trying to get the rtems4.11-gcc didn't work either. It resulted in an
gcc6 error which is known to appear when trying to build gcc5 which is
described here: https://gcc.gnu.org/ml/gcc-patches/2016-02/msg01409.html

Any recommendations?
