[OpenIndiana-discuss] Compiling tun driver for OpenVPN

[Russ Price]

Hi,

I'm trying to compile the tun driver so that I can move OpenVPN from a Linux 
system to my OI box. However, I'm not having much luck.

In order to get it to compile and link without errors, once I ran the configure 
script I had to change solaris/Makefile, as follows:

* added -m64 to the CFLAGS variable
* added -melf_x86_64 to the ld options

I also changed DRV_DIR to /usr/kernel/drv/amd64 for good measure. Well, after 
compiling it, I tried to install it, and got:

This is on oi_148b (Illumos kernel), but I also had the same problems with the 
old oi_148. Obviously, I'm doing something wrong here, but I'm stumped.
