Trying to compile the tap driver source code
Hi anyone know how to compile the source code of the tap driver? I am trying to edit some code in there to make the tap driver update the users internet connection icon to display a connected status.

Re: Trying to compile the tap driver source code
I was compiling the TUN/TAP driver and bumped into problems getting it to work in Solaris 10 on SPARC64.
After much searching, I found the solution at http://openvpn.net/archive/openvpn-user ... 00254.html.
The important parts are (edited a bit):
# Sun Studio targetting 64 bit SPARC
% cc -D_KERNEL -xarch=v9 -c tun.c
# Sun Studio targetting 64 bit x86
%cc -D_KERNEL -xarch=amd64 -xmodel=kernel -c tun.c
# Sun Studio targetting 32 bit
% cc -D_KERNEL -c tun.c
# GNU C Compiler targetting 64 bit SPARC ( optional: mtune=ultrasparc -O2 )
% gcc -D_KERNEL -m64 -mcpu=v9 -mcmodel=medlow -fno-pic -mno-fpu -ffreestanding -nodefaultlibs -c tun.c
# GNU C Compiler targetting 64 bit x86 ( optional: mtune=opteron -O2 )
% gcc -D_KERNEL -m64 -mcmodel=kernel -mno-red-zone -ffreestanding -nodefaultlibs -c tun.c
# GNU C Compiler targetting 32 bit
% gcc -D_KERNEL -ffreestanding -nodefaultlibs -c tun.c
The linking is the same for all
% usr/ccs/bin/ld -r -o tun tun.o
The destination is different depending on the architecture:
# 64 bit sparc
cp tun /usr/kernel/drv/sparcv9/tun
# 64 bit x86
cp tun /usr/kernel/drv/amd64/tun
# 32 bit
cp tun /usr/kernel/drv/tun
