## Dependencies needed to build/run
|
||
|
|
[EGL](../../README.md#egl)
|
||
|
|
|
||
|
|
## Prerequisites
|
||
|
|
|
||
|
|
Download and install the [CUDA Toolkit 11.5](https://developer.nvidia.com/cuda-downloads) for your corresponding platform.
|
||
|
|
Make sure the dependencies mentioned in [Dependencies]() section above are installed.
|
||
|
|
|
||
|
|
## Build and Run
|
||
|
|
|
||
|
|
### Linux
|
||
|
|
The Linux samples are built using makefiles. To use the makefiles, change the current directory to the sample directory you wish to build, and run make:
|
||
|
|
```
|
||
|
|
$ cd <sample_dir>
|
||
|
|
$ make
|
||
|
|
```
|
||
|
|
The samples makefiles can take advantage of certain options:
|
||
|
|
* **TARGET_ARCH=<arch>** - cross-compile targeting a specific architecture. Allowed architectures are x86_64, aarch64.
|
||
|
|
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.<br/>
|
||
|
|
`$ make TARGET_ARCH=x86_64` <br/> `$ make TARGET_ARCH=aarch64` <br/>
|
||
|
|
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=<host_compiler>** - override the default g++ host compiler. See the [Linux Installation Guide](http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#system-requirements) for a list of supported host compilers.
|
||
|
|
```
|
||
|
|
$ make HOST_COMPILER=g++
|
||
|
|
```
