# link-order2.test: make sure that depdepls are added right after
# the libs that pull them in: necessary at least for static linking
# and on systems where libraries do not link against other libraries.
#
# We test by overriding one symbol from a depdepl library.
# Test both a libtool library and a non-libtool library (simulated
# by removing the .la file, and setting $shlibpath_var so it is
# found at runtime). In order to ensure that the depdepl is
# actually loaded in each case, we also use an unrelated symbol
# from it directly in the main program. We test for failure by
# reversing the link order.
# We test both static and shared: it should work in both cases.
# But for the static case to work, the two symbols in the depdepl
# need to be in separate object files, otherwise duplicate symbol
# definitions can happen.
# The shared case fails on AIX without runtimelinking and on Darwin.
# On Darwin, using shared libs this only works without -no-undefined
# and only with MACOS_DEPLOYMENT_TARGET 10.2 and earlier
# (in that case $allow_undefined_flag contains -flat_namespace).
