Does anyone have a macro that will correctly determine when -rdynamic and/or -Wl,--export-dynamic can be used? I'm not using libtool but I'd like my application to be built such that functions in it can be invoked by dynamically loaded objects. I saw http://www.mail-archive.com/autoconf@xxxxxxx/msg15247.html but there was no definitive response... has anyone come up with something since then? I'd prefer to not invoke a test executable, to preserve cross-compiling. Thanks!
Paul,I think you're not getting a response because you're asking a lot. Without testing by running an executable, this can't be determined behaviorally, so your best bet is some sort of lookup. I would suggest you write your own macro, where you set the flag based on known system information, and barring that try some link-time flags and use one that doesn't generate any errors.
