OpenVPN and QNX4: is there a port?

QNX DEVELOPERS Porting
1

Did anyone attempt a port of OpenVPN to QNX4?

configure says
need function vsprintf() from C99 standart, but your have qnx4 understanding only C89 standart.
NO LUCK!!!

It usually possible to provide souce code for function such as vsprintf, but other issue will most definitely creep up.

Yes, Mario, the main perils are still ahead…

With just a very trivial hacking of ./configure and adding #include <sys/select.h> into some two or three files I was able to have make check succeed with both of it’s tests.

Now I need some way to emulate what LINUX calls tun and|or tup device. What comes first to my mind is hacking with Net.fd but I’m not sure.

Please comment.
