[New-bugs-announce] [issue3876] multiprocessing does not compile on *BSD and potentialy other systems

[Henry Precheur]

New submission from Henry Precheur <henry at precheur.org>:

Compiling `multiprocessing` on OpenBSD fails. `iovec` is not declared.

Adding the following line to multiprocessing.c solves the problem:
#include <sys/uio.h>

But right after I got:
./python:build/lib.openbsd-4.4-amd64-2.6/_multiprocessing.so: undefined
symbol 'sem_timedwait'

It looks like multiprocessing is using a function that is not defined in
OpenBSD and very likely on other BSD's (FreeBSD & NetBSD don't have a
man page for this function)

According to this page, some other systems don't have this function:
