Installation Structure

This page details the installation tree of the SDK: where the installation is located, how multiple versions are managed, what is contained in each subdirectory, and so on.

Versioning

The SDK’s structure allows you to have multiple versions installed simultaneously.

When you install a new version, it will be located in mrs-sdk-qt/<version>/, where <version> is the exact version of the release.

You can use the mrs-sdk-manager tool to select which version to activate.

Top-level tools

The mrs-sdk-qt/bin directory contains tools that are managed/installed independently of the actual SDK installations.

Right now, this list just includes mrs-sdk-manager, which is meant to be installed on its own and then used for downloading new SDK versions.

The current installation

The mrs-sdk-qt/current symlink defines the “active” version of the SDK. It is useful for abstracting out SDK version numbers when writing CMake/QMake configurations for projects: instead of specifying the version number in the path, you can simply say MRS_SDK_QT_ROOT/current/....

This symlink is controlled by the mrs-sdk-manager tool.

SDK components

Each independent SDK version contains its own versions of each component of the SDK; in other words, each installed version is self-contained.

Note that paths in this section are described relative to MRS_SDK_QT_ROOT/<version>, the top level of an installed SDK version.

Qt libraries

The mrs-sdk-qt Qt/C++ library is the centerpiece of the SDK.
