Library Dependency¶

Some example applications are dependent on specific versions of the AMD Vitis™ libraries, specifically:

VVAS package name vvas-accel-libs in PetaLinux (renamed from ivas-accel-libs in 2021.1 and older tools) or vvas-essentials in Ubuntu® (GitHub page)
Vitis-AI or VAI, package name vitis-ai-library (GitHub page)
XRT and ZOCL (GitHub page)

The libraries are not always backward compatible; to use the example applications, you need to install a specific versions of those libraries. When example applications are installed apps through a package feed or docker (per the deployment documentation), the appropriate library versions are installed by default. When the applications are installed manually (such as the flow in Yocto port Example), you need to take care to install specific versions.

These are the specific library versions verified with the released example applications:

BSP/App Version	XRT/ZOCL Version	Vitis-AI Version	VVAS Version
2022.1	202210.2.13.479	2.5.0	2.0
2021.1	202110.2.11.0	1.4.0	1.0(IVAS)
2020.2	202020.2.8.1	1.3.0	1.0(IVAS)

NOTE: ZOCL is a XRT dependency; you must always install ZOCL first, otherwise the XRT installation will install the latest ZOCL as a dependency. Similarly, Vitis-AI is a VVAS dependency, always install Vitis-AI first; otherwise the VVAS installation might install the latest version of Vitis-AI as a dependency.
