Dear Dealii_group,
I am currently learning Dealii and have successfully compiled dealii-9.6.0
using Visual Studio 2019 with the default settings, without encountering any
issues.
However, after creating a blank C++ project in Visual Studio 2019 and
copying the code from the step-1 tutorial into the project, I encountered the
following errors during debugging:
Error C2995: “T desul::Impl::atomic_oper_fetch(const Oper &,T *const
,dont_deduce_this_parameter<const T>::type,MemoryOrder,MemoryScope)”: function
template already defined step1
C:\dealii-9.6.0\deal.II\bundled\kokkos-3.7.00\tpls\desul\include\desul\atomics\Generic.hpp 326
Error C2995: “T desul::Impl::atomic_fetch_oper(const Oper &,T *const

template already defined step1

Error C2572: “desul::Impl::atomic_oper_fetch”: redefinition of default

C:\dealii-9.6.0\deal.II\bundled\kokkos-3.7.00\tpls\desul\include\desul\atomics\Generic.hpp 319
Error C2572: “desul::Impl::atomic_fetch_oper”: redefinition of default

C:\dealii-9.6.0\deal.II\bundled\kokkos-3.7.00\tpls\desul\include\desul\atomics\Generic.hpp 240
Despite multiple attempts, I have not been able to resolve the issue. Could
you please advise me on how to fix this?
Wei:
I'm not particularly familiar with Visual Studio, but have a couple of
suggestions:
* As a general rule, setting up deal.II projects "a blank C++ project in
Visual Studio 2019 and copying the code from the step-1 tutorial into the
project" is likely not going to work. You need to also copy the CMakeLists.txt
into it, and let cmake do its magic to properly set up compiler flags and all
sorts of other things. Is that what you did? If you really started with a
blank project, can you compile step-1 in its original directory, using cmake
to set up the project?
* Do you happen to have access to a newer version of Visual Studio? 2019 is a
good while ago, newer compilers might have this fixed.
* You say that you "encountered the following errors during debugging". Do you
mean during "compiling"? Or which part of the build process is producing this
error? Perhaps during linking?
Best
