Philip covered the rest in the other thread, but this remains:
Why does not the OS load the dependency (libpthread and C)
automatically, how do I make it do that, and on this topic, to your
perception is there anything I not understood?
libc had weak functions which needed to be overridden from libpthread;
if pthread was dlopen()ed without being dynamically linked to a binary,
it was too late to do this.
There have been various iterations; the -znodlopen linking was still
relatively recent, before that there wasn't anything preventing you
from dlopen(somelib_needing_pthread) but because it didn't override
the libc functions, you would run into nasty bugs and broken behaviour.
Thank you very much for your clarifications.
Haha OMG - so my "why won't my library dependencies chain autoload"
question was actually libpthread specifics in sheep's clothing, haha.
(I had a wrapper atop dlopen() which made it even more un-obvious.)
Who could have guessed. Thanks again.
