NetSurf on ARMv7 platforms
by John-Mark Bell
Afternoon,
So, NetSurf runs mostly ok on ARMv7 platforms with their backwards
incompatible unaligned LDR behaviour turned on. Tinct, however, appears
to perform some LDRs from unaligned addresses, resulting in crashes.
Here's a backtrace:

Amiga Revival 2009
by Chris Young
All
I have a confirmed (small) table at Amiga Revival 2009 show in Enfield
this December (on the 12th I think - AFAIK there is no website for it
yet)
I intend to take along my SAM440EP to show off NetSurf running on
AmigaOS 4.1. The GTK version will also be on show. I do not have the
hardware nor (if the small tables are the ones I think they are) the
space to show any other version - although I know the organiser quite
well and a bribe might get me a bigger table ;). Unfortunately this
also includes the AmigaOS 3 SDL-Framebuffer compile, which I'm sure
would be of interest to the visitors, so I'll have a go at getting
that running on UAE for the event.
Any of the devs are of course welcome to join me if they fancy making
the trip. If there are any posters etc I can borrow/print out to make
the area "more NetSurfy", please let me know.

configuring Netsurf-framebuffer
by Moutusi De
Hi All,
I have compiled Netsurf {"netsurf-r9577.tar.gz"}
I have built it with Frame buffer option.
{Just to give a background: we are working on an embedded hand held
device, with internet connectivity}
I couldn't find any option to configure the proxy or port on this
version of Netsurf {From my company to access external website, I need
to configure proxy settings}.
Hence when I run/open Netsurf, I get the following error message.
-----------------------------------------------
"Sorry Netsurf was unable to display this page.
Failed Connect to www.netsurf-browser.org:80: Resource temporarily
unavailable"
-----------------------------------------------
Could anyone please let me know how to resolve this ?
Just to add. When I tried to connect to our company intranet, it was
working fine.
Thanks,
Moutusi.
