To build/examine a single sample, the individual sample solution files should be used. -> **Note:** Some samples require that the Microsoft DirectX SDK (June 2010 or newer) be installed and that the VC++ directory paths are properly set up (**Tools > Options...**).

To use the makefiles, change the current directory to the sample directory you wish to build, and run make: -``` -$ cd -$ make -``` -The samples makefiles can take advantage of certain options: -* **TARGET_ARCH=** - cross-compile targeting a specific architecture. Allowed architectures are x86_64, ppc64le, armv7l. - By default, TARGET_ARCH is set to HOST_ARCH. On a x86_64 machine, not setting TARGET_ARCH is the equivalent of setting TARGET_ARCH=x86_64.
-`$ make TARGET_ARCH=x86_64`
`$ make TARGET_ARCH=ppc64le`
`$ make TARGET_ARCH=armv7l`
- See [here](http://docs.nvidia.com/cuda/cuda-samples/index.html#cross-samples) for more details. -* **dbg=1** - build with debug symbols - ``` - $ make dbg=1 - ``` -* **SMS="A B ..."** - override the SM architectures for which the sample will be built, where `"A B ..."` is a space-delimited list of SM architectures. For example, to generate SASS for SM 50 and SM 60, use `SMS="50 60"`. - ``` - $ make SMS="50 60" - ``` - -* **HOST_COMPILER=** - override the default g++ host compiler.
