Holoscan SDK — Build from Source

Purpose

Build the Holoscan SDK from the nvidia-holoscan/holoscan-sdk source tree using its ./run script (which builds inside a Docker container), producing a local install tree consumable as a CMake dependency.

Prerequisites

• Linux host with NVIDIA GPU + driver (nvidia-smi).
• git, Docker with NVIDIA Container Toolkit (docker run --gpus all works), and docker-buildx-plugin.
• ~20 GB free disk for the build container + build/install trees.
• 10–30 min for a clean first build.

Limitations

• Only recommended when published packages (Conda / container / apt / wheel) don't fit — debug symbols, custom CMake options, or unsupported configs.
• Still requires Docker — the ./run script builds inside a container; this is not a true bare-metal build.
• Cross-compiling to aarch64 needs qemu-user-static on the host.
