gcc-8-20180225: recipe for target 'configure-target-libbacktrace' failed

[Siegmar Gross <siegmar dot gross at informatik dot hs-fulda dot de>]

Hi,

today I tried to install gcc-8-20180225 with accelerator support
on my "SUSE Linux Enterprise Server 12.3 (x86_64)" with gcc-6.4.0.
I used the following commands to download and build everything.

setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/usr/local/cuda/lib64
setenv CUDA_INC_PATH /usr/local/cuda/include
setenv CUDA_LIB_PATH /usr/local/cuda/lib64
set path = ( ${path} /usr/local/cuda/bin )

git clone https://github.com/MentorEmbedded/nvptx-tools
git clone https://github.com/MentorEmbedded/nvptx-newlib

wget ftp://gcc.gnu.org/pub/gcc/snapshots/LATEST-8/gcc-8-20180225.tar.xz
tar xf gcc-8-20180225.tar.xz
ln -s gcc-8-20180225 gcc-8.0.0
cd gcc-8.0.0
ln -s ../nvptx-newlib/newlib newlib
cd ..

mkdir make_nvptx-tools
cd make_nvptx-tools
../nvptx-tools/configure --prefix=/usr/local/gcc-8.0.0 \
  |& tee log.configure
make |& tee log.make
make install |& tee log.make-install
cd ..

mkdir gcc-8.0.0_build
cd gcc-8.0.0_build
../gcc-8.0.0/configure --prefix=/usr/local/gcc-8.0.0 \
  --target=nvptx-none \
  --enable-as-accelerator-for=x86_64-pc-linux-gnu \
  --with-build-time-tools=/usr/local/gcc-8.0.0/nvptx-none/bin \
  --disable-sjlj-exceptions \
  --with-newlib \
  --enable-newlib-io-long-long \
  --enable-languages=c,c++,fortran,lto \
  |& tee log.configure

Unfortunately, "make" breaks with the following error.

I was able to build that part for gcc-7.3.0 with a patched nvptx.c
file with the same commands. I would be grateful, if somebody knows
a solution or can fix the problem. Do you need anything else? Thank
you very much for any help in advance.


Kind regards
