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:

test:Goal

(Additional) test that must succeed for the component to be functional.

url:URL

URL with additional information, relative to http://www.swi-prolog.org/build/issues/. If not provided, the library file with extension .html is used.

optional:true

If the library does not exist, do not complain.

os:OS

One of windows, unix or linux. If present, the component is only checked for if we are running on a version of the specified operating system.

features:Goal

After successful evaluation that loading and basic operation of the component succeeds, run this to check additional features.

 check_installation is det

Check features of the installed system. Performs the following tests:

1. Test whether features that depend on optional libraries are present (e.g., unbounded arithmetic support)
2. Test that all standard libraries that depend on foreign code are present.
3. 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 optional_not_found (optional component is not present), not_found (component is not present) or failed (component is present but cannot be loaded).

 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.

See also

- check_component/1 should be used for checking that the component works.

 run_silent(:Goal, +Properties) is semidet[private]

Succeed if Goal succeeds and does not print any errors or warnings.

 run_collect_messages(Goal, Result, Messages) is det[private]

Run Goal, unify Result with true, false or exception(Error) and messages with a list of generated error and warning messages. Each message is a term:

message(Term,Kind,Lines)

See also

- message_hook/3.

 test_tcmalloc[private]

 archive_features[private]

Report features supported by library(archive).

 pcre_features[private]

 jquery_file[private]

Test whether jquery.js can be found

 check_on_path[private]

Validate that Prolog is installed in $PATH. Only performed if the running executable is a normal executable file, assuming some special installation such as the WASM version otherwise.

 test_installation is semidet

 test_installation(+Options) is semidet

Run regression tests in the installed system. Requires the system to be built using

cmake -DINSTALL_TESTS=ON

Options processed:

packages(+Boolean)

When false, do not test the packages

package(+Package)

Only test package package.

 check_config_files

Examines the locations of config files. The config files have moved in version 8.1.15

 update_config_files

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.

 check_autoload[private]

Find possible ambiguous predicates in the autoload index.

Re-exported predicates

The following predicates are exported from this file while their implementation is defined in imported modules or non-module files loaded by this module.

 test_installation is semidet

 test_installation(+Options) is semidet

Run regression tests in the installed system. Requires the system to be built using

cmake -DINSTALL_TESTS=ON

Options processed:

packages(+Boolean)

When false, do not test the packages

package(+Package)

Only test package package.
