Summary: OSX/pd 0.39: fix for loading externals using static libs
Initial Comment:
Hi all,
unlike with pd 0.38, externals that share equal symbol names (like
when they have been compiled using the same static lib) won't get
loaded, but rather bail out with a "linker error".
This can be easily fixed by including the
NSLINKMODULE_OPTION_PRIVATE option in s_loader.c
ret = NSLinkModule( image, filename,
NSLINKMODULE_OPTION_BINDNOW |
NSLINKMODULE_OPTION_RETURN_ON_ERROR |
NSLINKMODULE_OPTION_PRIVATE);
Is there a reason this has been taken out in pd 0.39?
best greetings,
Thomas

...this was kinda covered in the bugtracker last year:
"[ 1082938 ] sys_load_lib() on OSX too limited?"
https://sourceforge.net/tracker/index.php?func=detail&aid=1082938&group_id=55736&atid=478070
...I'd like to suggest we ditch the NSLinkModule() stuff on
OSX, as it's been deprecated since 10.3.x: the replacement
is (drumroll please), dlopen()! As a matter of fact, hans
and I have been using a patch to do just this in the most
recent development releases: it's currently available in
/packages/patches/darwin/darwin_dlopen.patch, which I would
attach, but it's not letting me atm...
...also, I strongly suggest that we make another change in
the building of externals, from bundles to dynamic libs:
-dynamiclib -mmacosx-version-min=10.3 -undefined
dynamic_lookup (or suppress)
...this works for everything I've tried, but admittedly I
haven't done it with all externals or flext...
