Choosing Architecture (Triplets)

Dependency management in Brisk is based on Vcpkg, and Vcpkg triplets are used to select the target architecture and environment.

If you're unsure which triplet to choose, these are default used by Brisk:

  • For prebuilt dependencies: uni-osx (arm64/x86_64 universal binaries)
  • For custom build: arm64-osx for ARM-based Macs (or x64-osx for Intel-based Macs)

uni-osx

The uni-osx triplet is supported only with prebuilt binaries and dependencies because Vcpkg does not support building universal binaries for macOS. This triplet is a synthetic one used by Brisk to represent macOS universal binaries that combine x64-osx and arm64-osx binaries. To build dependencies, use one of the Vcpkg-supported triplets: x64-osx or arm64-osx.
Alternatively, use prebuilt dependencies if you need to work with universal binaries.

x64-linux (x86_64)

x64-windows-static-md (x86_64)

Note that the x64-windows and x86-windows triplets are not supported by Brisk, and the build will fail if any of these triplets is used.

All these triplets use static linking for dependencies and dynamic linking for the C runtime (CRT).

Note that Vcpkg uses different default settings for Windows (x64-windows) and macOS (x64-osx).

Dependencies linking

Currently, Brisk supports only static linking of dependencies; dynamic linking for Brisk libraries will be available in a future release.

Setting Triplet

  1. You can set VCPKG_DEFAULT_TRIPLET environment variable globally to override default triplet for your system, or
  2. export VCPKG_TARGET_TRIPLET environment variable for Brisk build, or
  3. set -DVCPKG_TARGET_TRIPLET=<TRIPLET> CMake variable when configuring build.

This applies to building Brisk from source and building applications that use the Brisk libraries.

Make sure that the triplet used when building the Brisk libraries (and dependencies) matches the triplet used for the application. For prebuilt binaries or dependencies, the triplet is always added to the archive filename (Brisk-Prebuilt-v0.9.7-arm64-osx.tar.xz).

For more information, consult the official Vcpkg documentation.
