Question about compiling with CUDA

[Justin O'Connor]

Howdy!

I'm working on making a Dockerfile that will let me use deal.ii with CUDA. However, when I run make install, I get the following error:

Error: Internal Compiler Error (codegen): "casting aggregate to non-void type is not supported!"

make[2]: *** [source/fe/CMakeFiles/object_fe_debug.dir/build.make:713: source/fe/CMakeFiles/object_fe_debug.dir/fe_values.cc.o] Error 2
make[2]: *** Waiting for unfinished jobs....

I'm hoping this is a known issue and I'm just doing something silly. Any pointers would be greatly appreciated.

My Dockerfile is attached if that is of any use to anyone.

Thank you,

Justin

Justin,

a docker file that we are using in a different project can be found at https://github.com/arborx/ArborX/blob/master/docker/Dockerfile in case that helps.

In general, I would advise against using nvhpc/nvc++ which proves to be pretty buggy as compared to nvcc/nvcc_wrapper or even (clang++ which is another option for a compiler supporting CUDA).

Anyway, it seems the current configuration is using nvcc_wrapper. What does the failing compile-line look like? What is the host compiler (I guess g++ but which version)?

Best,

Daniel

I'm now just using your dockerfile (thanks for the tips on it), and I am trying to install deal.ii at the end.

Adding this to the end of it:

RUN apt update && apt install -y libblas-dev liblapack-dev

WORKDIR /opt

ENV DEALII_VERSION 9.5.1

RUN wget --no-verbose https://www.dealii.org/downloads/dealii-$DEALII_VERSION.tar.gz

RUN gunzip -c dealii-$DEALII_VERSION.tar.gz | tar -xof -

ENV DEALII_DIR /opt/dealii-$DEALII_VERSION

WORKDIR $DEALII_DIR

RUN pwd

RUN mkdir build

RUN mkdir dealii_installed

WORKDIR $DEALII_DIR/build

RUN cmake $DEALII_DIR -DCMAKE_INSTALL_PREFIX=opt/dealii_installed \

   -DCMAKE_CXX_COMPILER=clang++ \

   -DDEAL_II_WITH_TBB=ON \

   -DDEAL_II_WITH_MPI=ON \

   -DDEAL_II_MPI_WITH_DEVICE_SUPPORT=ON \

   -DDEAL_II_WITH_LAPACK=ON \

   -DDEAL_II_WITH_BLAS=ON \

   -DDEAL_II_WITH_64BIT_INDICES=ON \

   -DKOKKOS_DIR=$KOKKOS_DIR \

   -DDEAL_II_WITH_CUDA=ON

gives the attached error, still saying the compiler and linker flags are the issue?

short version:

CMake Error at cmake/setup_finalize.cmake:126 (message):
 

    Configuration error: Cannot compile a test program with the final set of
    compiler and linker flags:
      CXX flags (DEBUG): -openmp-simd -pthread -ffp-exception-behavior=strict -Og -ggdb -Wa,--compress-debug-sections
      LD flags  (DEBUG): -rdynamic  -pthread -fopenmp=libomp -ggdb -Wl,--compress-debug-sections=zlib
      LIBRARIES (DEBUG): dl;
   

 

Call Stack (most recent call first):
  cmake/macros/macro_verbose_include.cmake:19 (include)
  CMakeLists.txt:123 (verbose_include)

Thank you so much for all your help already,

Justin

For posterity, ere's a dockerfile I got working that installs deal.ii with cuda capability. :)

Thanks,

Justin

I'm glad you found something that is working for you!
