Hi Thomas,
thank you very much for your help. That's exactly what I wanted.
I tried again and was successful.
Kind regards
Siegmar

Right, such things are not supported for a "--target=nvptx" compiler.
But, if your desire is to just enable additional languages, without
offloading support for them (which doesn't exist, as discussed in my
other email), then the solution is to just specify them in
"--enable-languages" for your "gcc-8.0.0_host_build" (host compiler) but
not for your "gcc-8.0.0_build" (nvptx offloading compiler), keeping the
latter at "--enable-languages=c,c++,fortran,lto".
Specifically:
I used the following commands to 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 )
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++,objc,obj-c++,fortran,go,lto \
Continue to use "--enable-languages=c,c++,fortran,lto" here.

That should work fine.
