project('dep versions', 'c', 'cpp')
Add various tests for versioned dependency checking Both pkg-config and subproject-based dependencies Linux-like because we need zlib for the tests to work
9 years ago
# Find external dependency without version
zlib = dependency('zlib')
# Find external dependency with version
zlibver = dependency('zlib', version : '>1.0')
assert(zlib.version() == zlibver.version(), 'zlib versions did not match!')
# Find external dependency with conflicting version
interpreter: Add a type_name method to DependencyHolder And remove the InternalDependencyHolder class. In some cases we need to know the type of dependency we are dealing with. For example in GStreamer if the dependency is not an internal one, then we need to get some env var from pkg-config to know where to find some plugins necessary to run some tests.

zlibver = dependency('zlib', version : '<1.0', required : false)
assert(zlibver.found() == false, 'zlib <1.0 should not be found!')
Allow many version conditions for pkg-config deps Sometimes we want to restrict the acceptable versions to a list of versions, or a smallest-version + largest-version, or both. For instance, GStreamer's opencv plugin is only compatible with 3.1.0 >= opencv >= 2.3.0

dependency('zlib', version : '<=9999')

# Find external dependencies with multiple version restrictions
dependency('zlib', version : ['>=1.0', '<=9999'])
if dependency('zlib', version : ['<=1.0', '>=9999', '=' + zlib.version()], required : false).found()
error('zlib <=1.0 >=9999 should not have been found')

# Find an internal dependency again with the same name and a specific version

Try using already setup fallback subprojects before using native dependency In the case the main project set a subproject for a dependency another subprojects uses, that other subproject should rather use the first subproject rather that using native dependency. For example in gst-all we set all GStreamer modules as subprojects and, gst-plugins-base is set after gstreamer core, and we want gst-plugins-base to always use GStreamer core from the subproject and not the possibly avalaible native one.

fakezlib_dep = dependency('zlib',
fallback : ['somelib', 'fakezlib_dep'])
assert(fakezlib_dep.type_name() == 'internal', 'fakezlib_dep should be of type "internal", not ' + fakezlib_dep.type_name())
Add get_version() method to all dependencies We unconditionally check the version of all dependencies, so without this regen will fail if you use that dependency.
