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

the library file with extension

- If the library does not exist, do not complain.
- One of
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

not_found (component is
not present) or

- 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.

- Succeed if Goal succeeds and does not print any errors or
- run_collect_messages(Goal, Result, Messages) is det[private]
- 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.
The following predicates are exported, but not or incorrectly documented.
