# Test flags for controlling static/dynamic linking,
|
||||
# when creating programs.
|
||||
|
||||
##### NOTES #####
|
||||
#
|
||||
# - How do we test whether a library was linked statically?
|
||||
# We could
|
||||
# - try $NM on the program to see whether it includes the symbol definitions.
|
||||
# disadvantage: for uninstalled programs, we may need to find out the name
|
||||
# of the _real_ linked-against-uninstalled executable
|
||||
# (.libs/prog vs .libs/lt-prog etc).
|
||||
# - simply remove the libraries before execution. If the program still works,
|
||||
# then the library was linked statically.
|
||||
# -Does this work on all systems?
|
||||
# -No, it will fail on AIX with non-rtl-created libraries: plain `-static'
|
||||
# will only cause the linker not to consider `*.so' libraries, but only
|
||||
# `*.a'. The latter, however, may still be shared images. :-/
|
||||
# `-all-static' still works, however.
|
||||
#
|
||||
# It will not work with dlpreloading until we fix its related bug.
|
||||
#
|
||||
# Let's try the latter until we know better.
|
||||
|
||||
# - Test -Bstatic/-Bdynamic. It should work with all of:
|
||||
# - (un)installed libtool libraries
|
||||
# - non-libtool libraries
|
||||
# - direct or pulled-in libraries
|
||||
# - libraries of which there are only one kind available (TODO)
|
||||
# (in the static case, should having only the shared one provoke failure?)
|
||||
|
||||
# - Check no extraneous run paths have been added.
|
||||
|
||||
# - make sure -Bstatic/-Bdynamic cannot be mixed with -all-static (TODO)
|
||||
|
||||
# - should -Bstatic/-Bdynamic be mixable with -static or -static-libtool-libs?
|
||||
# Semantics could be as follows:
|
||||
# - `-static'/`-static-libtool-libs' set the default which is the initial
|
||||
# value, then `-Bstatic'/`-Bdynamic' override that
|
||||
# - `-Bdefault' resets to the default value given by the other switches.
|
||||
|
||||
# - TODO: test exposure for dlopened and dlpreopened modules,
|
||||
# without and with diverse static flag combinations.
|
||||
|
||||
# - TODO: test other tags: C++ etc.
|
||||
# (most likely the Sun compiler suite will be the only problem child).
