This library performs checks on the installed system to verify which
optional components are available and whether all libraries that load
shared objects/DLLs can be loaded.
- component(?Component, -Features) is nondet[private]
- This predicate describes the test components. Features is a dict
with the following components:
- (Additional) test that must succeed for the component to be

linux. If present, the component
is only checked for if we are running on a version of the
specified operating system.
- After successful evaluation that loading and basic operation
of the component succeeds, run this to check additional
- Check features of the installed system. Performs the following
- Test whether features that depend on optional libraries
are present (e.g., unbounded arithmetic support)
- Test that all standard libraries that depend on foreign
code are present.
- provides a test_installation predicate to run the tests
at runtime if the system was built with -DINSTALL_TESTS
If issues are found it prints a diagnostic message with a link
to a wiki page with additional information about the issue.
- check_installation(-Issues:list(pair)) is det
- As check_installation/0, but additionally returns a list of
Component-Problem pairs. Problem is one of

- test_component(+Properties) is semidet[private]
- Run additional tests to see whether the component really works.
- check_features(+Properties) is semidet[private]
- Check for additional features of the components.

- Run Goal, unify Result with

messages. Each message is a term:

- Report features supported by library(archive).
- Test whether jquery.js can be found
- Validate that Prolog is installed in $PATH
- test_installation is semidet
- test_installation(+Options) is semidet
- Run regression tests in the installed system. Requires the system to
be built using
false, do not test the packages
- Only test package package.
- Examines the locations of config files. The config files have moved
in version 8.1.15
- Move config files from their old location to the new if the file or
directory exists in the old location but not in the new.
