Re: [CMake] CXX and CUDACXX
I don't have any other suggestions. In general I recommend the script approach or using enable_language(CUDA). The enable_language approach should work, so I am curious what other issues you are seeing.

Re: [CMake] CXX and CUDACXX
The default implementation is to defer to CUDA for selecting what ever host compiler it would like. To make sure that CMake uses the same CXX and CUDACXX compiler you will need to explicitly state that either through the CUDAHOSTCXX env variable ( https://cmake.org/cmake/help/v3.12/envvar/CUDAHOSTCXX.html ) or with CMAKE_CUDA_HOST_COMPILER on the initial configuration of a project. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

[CMake] CXX and CUDACXX
Hi All, I'd like to understand the expectations with CMake 3.12+ with the following setup. project(foo LANGUAGES CXX CUDA) By default, should the CUDACXX compiler be using the found compiler for CXX for host-side compilation? What I'm seeing is that host-side compilation for CUDA is not passing -ccbin to NVCC or setting up the environment in a way that nvcc will use the CXX configured compiler but rather just using the c++ it finds on PATH. Is there a best practice for telling the CUDA language to use the CXX settings for host-side compilation? Thanks! -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
