Binaries from server¶

Hunter has internal mechanism of saving binaries of installed packages along with meta information about toolchain, build options and dependencies. This allow to not trigger same build on creation of new root directory. For example when user change version of OpenSSL from 1.0.1 to 1.0.2 it does affect Config-ID so new root will be created. But it will not affect how GTest builds (if it’s not a dependency) so GTest archive can be unpacked from cache. Such cache can be used locally or uploaded to server.

Details¶

Default server with binaries is ingenue/hunter-cache. Archives saved as assets to cache tag. Uploaded packages can be found by upload.* query on page with branches:

ingenue/hunter@upload.

Note that some toolchains may not work for the specific packages. Check status in job details. E.g. Qt is broken for iOS armv7s architecture, so we have to use ios-*-wo-armv7s toolchains:

Binaries/headers stored in archives. Archives are the result of packing CMAKE_INSTALL_PREFIX directory produced by cmake --build _builds --target install command. Idea is similar to CPack functionality but extended for non-CMake packages too.
