Re: [B2-devel] change to main_unix.cpp

[Geoffrey B. <geo...@in...>]

Ok, that's curious.  The sources I was building on Linux previously
had this diff

diff -r1.88 main_unix.cpp
846c846
< #if REAL_ADDRESSING && HAVE_LINKER_SCRIPT
---
> #if REAL_ADDRESSING && HAVE_LINKER_SCRIPT && PAGEZERO_HACK

But as you point out there doesn't seem to have been any activity on
this recently
so I'm not sure how I ended up with that diff -- I went to the web based cvs to
see if I could find the change and can't.

In any case, without the "PAGEZERO_HACK' flag to make that #if false, things
bomb immediately on linux.  Adding that "back" I can make forward progress.
I have no idea where that came from (a bug fix suggested on a forum?)

So, maybe I need to configure for linux differently -- I've been doing

./configure --enable-sdl-audio --enable-sdl-video

I'll try to figure out what is going on.
