# Test that declare_dependency(objects: ...) fixes issues with duplicated
# objects in the final link line, thanks to deduplication of dependencies.
# The commented declare_dependency() invocation using link_whole instead
# fails thusly:
#
# ar csrDT libbar.a libfoo.a.p/foo.c.o libbar.a.p/bar.c.o
# ar csrDT libfoo.a libfoo.a.p/foo.c.o
# cc -o prog prog.p/prog.c.o -Wl,--as-needed -Wl,--no-undefined -Wl,--whole-archive -Wl,--start-group libfoo.a libbar.a -Wl,--end-group -Wl,--no-whole-archive
# /usr/bin/ld: libfoo.a.p/foo.c.o: in function `foo':
# ../foo.c:3: multiple definition of `foo'; libfoo.a.p/foo.c.o:../foo.c:3: first defined here
project('Transitive declare_dependency(objects)', 'c')
libfoo = static_library('foo', 'foo.c')
#foo = declare_dependency(link_whole: libfoo)
foo = declare_dependency(objects: libfoo.extract_all_objects(recursive: true))
libbar = static_library('bar', 'bar.c', dependencies: foo)
