Create an empty project

$ xmake create -P test -l cuda
$ cd test
$ xmake

::: tip NOTE Starting with v2.2.7, the default build will enable device-link. (see Separate Compilation and Linking of CUDA C++ Device Code) If you want to disable device-link, you can set it with set_policy("build.cuda.devlink", false). :::

::: tip NOTE Device functions in cuda source files should be device-linked once and only once. On targets with kind binary or shared xmake will automatically perform the device-link which takes the static libraries they depend into account, while for static targets by default will not be device-linked. However, if the final binary or shared target do not contain any cuda files, the device-link stage could be missing, resulting in an undefined reference error. In this case the static target should be set add_values("cuda.build.devlink", true) manually. :::

Xmake will detect Cuda SDK automatically and we can also set the SDK directory (or SDK version for default installations) manually.

$ xmake f --cuda=/usr/local/cuda-9.1/
$ xmake f --cuda=9.1
$ xmake

Specify CUDA SDK Version

Starting from v3.0.5, you can specify the CUDA SDK version via the --cuda_sdkver command-line option, giving you precise control over CUDA compilation:

$ xmake f --cuda_sdkver=11.8
$ xmake

Supported version values include:

• 11.8 - Specify CUDA 11.8 version
• 11.x - Specify CUDA 11.x series version
• auto - Auto detect (default)
