[petsc-users] Unable to Install Kokkos and Find Cuda Compiler

[Junchao Zhang]

Hi Ted,
  I saw in configure.log,
      --with-cudac=/usr/local/cuda-11.4/bin/nvcc
--with-cuda-dir=/usr/local/cuda
  I suppose /usr/local/cuda is just a symbol link to /usr/local/cuda-11.4/
  I don't know why this error
      /usr/include/c++/11/cmath:45:15: fatal error: math.h: No such file or
directory
  To know whether it was because petsc did not configure Kokkos correctly,
or there was something wrong with your environment,  you can download
Kokkos and install yourself to see if you can succeed.  Make sure
/usr/local/cuda-11.4/bin/nvcc on your $PATH.

  For example, I download kokkos under my $HOME and install to
$HOME/tmp/kokkos

$ cd $HOME
$ git clone https://github.com/kokkos/kokkos.git
$ cd kokkos
$ mkdir build
$ cd build
$ cmake ../ -DCMAKE_INSTALL_PREFIX=$HOME/tmp/kokkos
-DCMAKE_CXX_COMPILER=g++ -DKokkos_ENABLE_SERIAL=ON -DKokkos_ENABLE_CUDA=ON
-DKokkos_ARCH_VOLTA75=ON -DKokkos_ENABLE_CUDA_LAMBDA=ON
-DCMAKE_CXX_STANDARD=17
$ make -j install
