libpthreads vs libthr

Luca, Burton, or other core / really smart people; any ideas if or why
one thread library will work better for ntop than another? If so, if
you could generally describe the scheduling / threading environment that
ntop likes best, us *BSD guys can maybe make things work better in our
world. FreeBSD (others?) support "Linux Threads" with a little effort,
but if nTop behaves significantly better in that threading model, then
I'll make it so - or maybe just run it on a linux box! It appears I
will be "forced" to run this on Solaris 10 sooner than later, so
hopefully I won't have TOO much problems with the build and operation on
that platform!



TIA!



Gary

Re: libpthreads vs libthr [In reply to]

PS, yes I read the FAQ (again) and several/many articles and papers on
threading and scheduling behavior. The warning during ./configure?
About sched.h being present but can't be compiled still worries me.
I'll bump that post and see if I can get any attention.

my FreeBSD experience is limited. I can tell you that I had issues with threads too (but I have used FreeBSD 7). A friend of mine replaced some thread libraries and changes something on the system (I can't recall honestly) and the ntop worked. ntop relies on threads so I cannot remove them. From past emails I have understood that changing the thread library solved the problem. Is this correct? Apparently not.
